Installation and Operation Manual ISDN – VoIP Gateway 1 Introduction TD 92326GB DRAFT The VoIP gateway IP 6000 is the gateway for ISDN primary rate interfaces in the Ascom VoWLAN system. It serves as a link between traditional telephony and IP telephony. The VoIP gateway has four PRI interfaces and can be used with several different configurations. Two PRI interfaces may be switched to ISDN, thus providing 60 lines simultaneously.
Installation and Operation Manual ISDN – VoIP Gateway 1.3.1 TD 92326GB DRAFT Important, Notes and Tips IMPORTANT: Pay attention to these notes, to prevent damage to the gateways or other equipment, and to ensure your own safety. Note: Notes provide you with information, that you may first need to become familiar with, in order to configure the gateway properly. Tip: 2 Tips provide you with information on how to use the gateway in a particularly easy or convenient way. Description 2.

The serial number label is placed on the underside of the housing. Figure 2.
Installation and Operation Manual ISDN – VoIP Gateway 3.2 TD 92326GB DRAFT Access to the Local Area Network (LAN) The gateway is delivered with a default configuration. In this configuration the gateway will try to configure the IP parameters via DHCP. The installed DHCP client is thus active and the DHCP server, which is also incorporated, is deactivated. • Ask your network administrator whether your network has a DHCP server.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT address of your gateway, see chapter 2.5 The MAC address/Serial number on page 5. • If the power supply is interrupted while the gateway is in automatic mode, DHCP client mode will be activated. You will now be assigned an IP address by the DHCP server in the network. • You can display the allocated IP address as follows.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT Under Linux, you can use the “nmblookup” command for this purpose, provided the “SAMBA” package has been installed: [dvl@cobalt ~ 2] $. nmblookup ip4002-XX-XX-XX Got a positive name query response from 195.226.104.220 (195.226.104.220 ) 195.226.104.220 ip400-XX-XX-XX<00> [dvl@cobalt ~ 3] $. Tip: The installation can be concluded using your Web Browser or, using command lines with the help of Telnet.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT IMPORTANT: If the computer is connected to the network by a coaxial-cable (thin Ethernet) Remove the BNC-T-piece from the Ethernet adapter. Make sure that the network cable is not split in the process, as otherwise your network will no longer work. 3 Set the Ethernet Switch on the back to “connect to PC”. This makes the gateway operate like an Ethernet Hub for your computer.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT 11 Set the Ethernet Switch on the back to “connect to Hub”. The gateway now operates like a standard Ethernet terminal and can be connected to a hub or switch. 12 Connect the gateway's Ethernet socket to your Hub or Switch or to the corresponding wall socket. Do not forget to re-connect your computer to your own network and to restore its original IP-configuration.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT 3 If necessary, configure the WAN interfaces, i.e. specify the parameters for your Internet or intranet access, if you also intend to use the gateway as an ISDN or a VPN router. Tip: The VoIP gateway IP 6000 can also be used as a ISDN router. To do that, the IP 6000 also need the optional HDLC hardware module. The IP 6000 can also be used as VPN routers (PPPoE) 4.3 4 Configure the call routing.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT on the left is used to navigate through the configuration. Entries can only be made in the right-hand window. Figure 3. Applet Gateway Explorer The buttons (Save, Activate, Reset, Reset when idle and Cansel) in the button bar at the top of the applet window relate to the entire configuration. Refer to section 4.4 Changing and Saving the Configuration on page 12 for the description of these functions. Other buttons (Add, Remove, etc.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT 1 Make your configuration changes. 2 Click the Activate button. The new configuration is now saved in the working memory and can be tested. However, the configuration has not yet been saved to the non-volatile memory and will be lost if the gateway is cold started. Note: A cold start here means a restart following an interruption to the power supply.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT The gateway's DHCP function has a total of four operating modes: Mode Function Use Off No DHCP function When you want to configure fixed IP parameters. Server DHCP servera active Connected devices are assigned an IP address by the gateway. Client DHCP client active The gateway gets its IP configurationfrom a DHCP server in the network, section 5.1.1 DHCP configuration options on page 15 lists the DHCP options used.
Installation and Operation Manual ISDN – VoIP Gateway 5.1.1 TD 92326GB DRAFT DHCP configuration options Besides the IP address actually assigned, your gateway's DHCP client processes the DHCP options specified in the table below, provided that they were supplied when the DHCP lease was granted. Options supplied via DHCP always overwrite any parameters defined in the gateway configuration.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT IMPORTANT: Note the configuration of the switch, before setting the VLAN ID. The gateway can access the VLAN ID and the VLAN priority using DHCP. Appendix C for more information on the DHCP client, the VLAN ID and the VLAN priority. 5.2 WAN Interfaces Your gateway can also be used as an ISDN or PPPoE (PPP over Ethernet) router.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT The IP 6000 has 32 available PPP interfaces.

Figure Figure 6.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT One specific application of the ISDN WAN interface is to dial-in to the gateway for maintenance purposes. This enables remote maintenance of the gateway, without necessarily having access to the local IP network, as illustrated by figure 8.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT The connect link is used to establish the selected connection. The clear link, by contrast, is used to clear the connection. Channel bundling (multi link) The gateway support channel bundling on two ISDN B channels (128 kbit/s). WAN interface addresses The WAN interfaces of a router are usually assigned their own IP addresses (usually from a special transfer network).
Installation and Operation Manual ISDN – VoIP Gateway 5 TD 92326GB DRAFT Clear the following check boxes: • Multilink • Permanent connection The "Channel" field is significant for permanent connections only and thus can't be changed here. • Allow incoming calls • Assign remote IP address Tip: As a result, the called party will not be assigned an IP address whilst the PPP connection is being established. This is unusual for outgoing calls. 6 Leave the "Check remote number" field empty.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT 7 Enter the number to accept incoming calls in the "Subscriber number" field. This field should not be left empty. Tip: If this field remains empty, all data calls will be accepted at the selected ISDN interfaces. In this case however, it is not possible to assign these calls to the various PPP interfaces. Such configurations should thus be avoided. 8 Select the "Allow incoming calls" check box.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT PPPoE connections are basically dial-up connections, just like ISDN connections. However, a number of providers offer Flat Rates with charges which are independent of the call duration. In such cases, it is possible, and also makes sense, to keep the PPPoE connection open permanently. Network address translation (NAT) is not required if the connection is operated with unofficial, but known, IP addresses.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT Dial-up of the VoIP gateway (client) to a PPTP server 1 In the configuration applet, select the IP Interfaces > PPPn Interface path of the PPP interface to be configured. 2 Select the "PPTP" protocol from the "Port" menu. 3 Enter the IP address of the remote PPTP server, with which you wish to set up the VPN, under "PPTP-IP address". 4 Switch off the option "Allow incoming calls".
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT • The called gateway itself is assigned the IP address 192.168.0.254. Tip: Under normal circumstances this IP address should not overlap with the address of a device on the LAN. If however, there is a device on the network with the IP address 192.168.0.254, the gateway itself will not be able to communicate with this device. This address is programmed permanently into the gateway.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT An example should illustrate the principle: After entering a telephone number, for which ENUM information is available, the call is first switched to a conventional network connection. If no-one answers, the call is forwarded to the registered mobile telephone number. If no connection can be made, the message can be recorded and sent to an Email address as an audio file.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT In the next step we will configure an interface for incoming calls, if this hasn't already been done. The interface must permit the acceptance of calls from any IP address, without previous registration: 1 In the configuration applet, select the path Config > VoIP Interfaces > GWn, where n corresponds to the VoIP interface to be configured, for example, GW3.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT 1 Click on the Add map button. 2 In the "Called number in" field, enter the digits 000. With this entry, 000 is recognised as the international prefix and is removed. 3 Click on the Add map button. 4 In the "Called number in" field, enter the digits 00. 5 In the "Called number out" field, enter the country prefix. For Germany, for example, enter 49.
Installation and Operation Manual ISDN – VoIP Gateway 6 ISDN Interfaces TD 92326GB DRAFT The gateway also has two “virtual” interfaces, whose configuration is described in section 5.6 “Considerations on the configuration of the virtual interfaces” from page 96. The gateway has four PRI interfaces that may be switched to ISDN, thus providing 60 lines simultaneouslyI. To configure the ISDN interfaces you first need to decide about the following points: • Which devices you want to connect to the gateway.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT • "Suppress sending of FTY" suppresses the transmission of "facility information elements" on the interface. • "Provide inband progress tones" (in TE mode only) enforces the generation of tones (dial tone, ring tone, busy tone) also in TE mode (always generated in NT mode). • "Generate connected time" adds the local gateway time to every outgoing CONNECT message.
Installation and Operation Manual ISDN – VoIP Gateway Volume adjustment TD 92326GB DRAFT In some cases, it is desirable to adjust the basic volume level of an interface. The volume of the ISDN interfaces can be set, in the configuration applet, under Config > ISDN, tone and HTTP Interfaces > TEL or PRI under "Interface configuration" in the "Volume" field, in the range from -31 to +32. The units of the volumes setting are Decibels. No entry, or the value 0 corresponds to the factory setting.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT Single digit dialling on terminals on point-to-multipoint connections Normally, single digit dialling (overlapped sending) is not used to call terminals (i.e. devices in TE mode) on point-to-multipoint connections. Under certain circumstances however, it is possible for gateways to be connected to a PBX system in precisely this mode and then also support incoming single digit dialling (overlapped receive).
Installation and Operation Manual ISDN – VoIP Gateway 6.2.1 TD 92326GB DRAFT Usage at a public exchange line (dial-up or permanent connection) In this case, the gateway is connected to one of the ISDN-exchange lines from your network provider. This type of usage is only possible for tel1, tel2, PPP, PRI1 and S/T. PRI2 can only be operated in NT mode and is therefore not suitable for this type of connection.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT This setting is irrelevant for permanent connections. If the connection is operated in mixed mode (one B channel permanently used for a fixed connection, one B channel in dial up mode), the setting depends on the operating mode of the dial-up line (tel1,tel2, PPP and S/T only). 1 Remove "Connect PRI1 and PRI2 with relay" (only PRI1). 2 If CRC4 checksums are generated on the connection, clear the "No crc4"check box.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT This type of usage is only available for the tel1 and tel2 interfaces.

Installation and Operation Manual ISDN – VoIP Gateway 6.2.3 TD 92326GB DRAFT Use as a public exchange line for an ISDN-PBX In this case, the gateway interface is connected to an ISDN-PBX as the sole exchange line or as an additional line within an exchange line bundle. In this way, it operates like a “point-to-point” connection from your network provider. The interface must be operated in NT mode here. Consequently, the only interfaces suitable for this type of use are tel1, tel2 and PRI2.
Installation and Operation Manual ISDN – VoIP Gateway 13 TD 92326GB DRAFT "Called party" and "calling party number" do not usually have to be modified in any special way in this configuration. Refer here to section 6.2.7 Dealing with the various ISDN address types on page 39. The PPP and S/T interfaces are intended solely for connecting a public exchange line to the gateway. It is therefore not possible to connect an ISDN PBX system in this manner (refer however to section 6.2.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT In this case, the PBX is connected to the gateway in the same way as an exchange line, as described in section 6.2.1 Usage at a public exchange line (dial-up or permanent connection) on page 32. The connection provided by the PBX however is usually a "pointto-multipoint" connection. The "Point to Point" check box should be cleared accordingly.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT PBX has its own clock, the gateway can be operated in TE mode without any difficulty. This is possible at both ends of the connection.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT line. Refer here to section 6.2.7 Dealing with the various ISDN address types on page 39. 6.2.6 Looping the gateway into an existing public exchange line In some cases no other ISDN interface can be used to connect the gateway to the PBX. In such cases it makes sense to loop the gateway into the existing public exchange line.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT The call number type "unknown" therefore has to be standardized in order to evaluate call numbers within the gateway. This can be done with the help of entries in the so-called CGPN (calling party number) map and CDPN (called party number) map , which can be defined both on the ISDN interfaces, and in the individual gateway definitions.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT Figure 17. Default CGPN/CDPN maps Figure 18. Manipulation of the root number by means of CDPN maps 1 In the left half of the configuration applet, select the interface for which you want to set up call number modifications. 2 If necessary, extend the tree view by clicking the + sign next to the interface name. 3 Select one of the following lines on the left-hand side. • "Calling party num.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT replaced if the call number type is "subscriber" (abbreviation s) and the number begins with the code 47110815. Note that call numbers within the gateway are always processed in "unknown" format.That is why the result of a number replacement, for incoming calls, is always of the type "unknown" and the call number type of outgoing calls to be replaced is likewise always "unknown".
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT since, optionally, end points and gateways can also communicate directly with one another. Your gateway always includes a gatekeeper that you can use as desired. Gatekeepers and VoIP end points or VoIP gateways usually communicate via the so called RAS protocol. Your gateway can be used with or without RAS protocol. As far as the telephony features are concerned, no disadvantages result from operating without RAS.

Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT The device management is configured in the configuration applet in the "VoIP Interfaces" area. The devices are managed dynamically by means of "Registration" in the RAS (Registration, Admission and Status) protocol. First of all the registering device finds out which gatekeeper is responsible.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT Your gateway itself can also log on to another gatekeeper with RAS protocol as illustrated in Figure 20. Call sequence with two gatekeepers and RAS on page 45. This operating mode is configured in "Registration at Gatekeeper as endpoint" or "Registration at Gatekeeper as Gateway" mode. 7.1.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT Tip: Some ring tones might not be audible, if connections are established to end points with H.323 version 2. In this case, update the protocol of the remote entity. Disable H245tunneling In the basic settings, the voice data connection is negotiatedin the TCP signalling connectiona already available. A TCP connection of its own is established for this negotiation if "Disable H245tunneling" is activated.
Installation and Operation Manual ISDN – VoIP Gateway 7.1.5 TD 92326GB DRAFT Setting up a gatekeeper on another gateway If the gatekeeper is not to operate on its own gateway, a Remote gatekeeper address can be configured in the "VoIP Interfaces" area of the configuration applet. The gateway tries to log onto a remote gatekeeper, if its IP address is entered in the "IP address" field.

Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT An other way of saving bandwidth is by not transmitting any data during pauses in speech. Considerable bandwidth can be saved in this way, since only one party usually speaks at a time during a conversation. This function is referred to as "Silence compression" and can usually be activated without any loss of quality.
Installation and Operation Manual ISDN – VoIP Gateway 5 TD 92326GB DRAFT Create an alias entry for every VoIP device. This is done by clicking on the Add alias button. For VoIP end points, you should define the assigned extension number or MSN here as "E.164 Address" and the name as "H.323 Name". For VoIP gateways it is sufficient to define the name. Figure 21. Entering a VoIP device Please note that it is enough for the VoIP device to register with its name.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT • Create an appropriate Alias entry in the gatekeeper. The serial number is entered in the H.323 Name field and the telephone's extension number is defined in the E.164 Address field. • If the IP telephone is also to be assigned a “descriptive” name, then set up a further alias, with the same extension number as text, in front of the serial number alias. Enter the desired name as H.323 Name.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT Tip: It is practical to use the serial number followed by the interface description, for example IP21-04-00-00:TEL2. Note that automatic registration as described in section 6.2.1 “Special features, when configuring innovaphone devices” from page 114 does not work, as all gateway definitions need to operate with different aliases. 3 Set up routes between the gatekeeper and the interfaces (see Fig. 35 on page 115). Figure 23. Fig.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT • For a group of VoIP devices, enter the address of the IP network, where the authorised devices are located, under "IP address". Set the network mask for the network under "IP mask". In this way, you can define the group of authorised VoIP devices as you wish. It is not necessary, for the configured network to actually be an existing network. You allow access to all VoIP devices by setting the IP address to 0.0.0.
Installation and Operation Manual ISDN – VoIP Gateway 7.5 TD 92326GB DRAFT Routing via the ENUM protocol Another option for routing calls is to use the ENUM protocol. ENUM stands for a protocol, which has to do with mapping so-called E.164 numbers to Uniform Resource Identifiers (URI). With the help of the ENUM protocol, it is possible to check whether a number can be called via a cost effective Internet connection, or rather via an ISDN connection.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT figure 25 on page 57 shows a scenario in which calls are switched via VoIP between a telephone connected to gateway A and the ISDN network connected to gateway B. tel1 GW1 Call switching 1 2 A BC VoIP 3 D EF 4 GHI 5 J KL 6 MNO 7 PQRS 8 TUV 9 W XY Z 0 IP handset Route 1: tel1 >> GW1 Route 2: GW1 >> tel1 Gateway A GW1 VoIP PPP Call switching ISDN 016 Route 1: GW1 >> PPP Route 2: PPP >> GW1 Gateway B Figure 25.

The MSNs (529969 and 529096) assigned to a point-to-multipoint connection are mapped onto the internal extension numbers 20 and 30. Figure 27. Routes with call number replacement After all, it is occasionally necessary to define routes that depend on the calling number. To do this, so called "CGPN Maps" are attached to the Maps, very much in the same way as the Maps are attached to the routes.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT • whose route has specified the source interface of the current call as a permitted interface in the "Enable calls from interfaces" list and • whose dial prefix specified in the "Called number in" field matches the called number of the current call, and whose "Verify CGPN" box is not selected or • whose "Verify CGPN" check box is selected and the calling number of the current call matches the "Calling number in" entry, "CGPN maps" att
Installation and Operation Manual ISDN – VoIP Gateway 11 TD 92326GB DRAFT A # can be transmitted to mark the end of the call number by setting the "Add # to number "option. This is required for devices, such as from Cisco, which are unable to identify the end of a number properly. You can actuate the Add map button a number of times if you want to specify a number of routes for a set of sources.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT figure 30 on page 61 shows the configuration of a 0 as the access digit for an exchange line. Figure 30. Configuration of an exchange access code To ensure here that an exchange access digit of 0 is placed in front of the calling number for all incoming calls via the exchange line, a "CGPN (calling party number) map" must be created for the respective interface. The basic procedure for this is described in section 6.2.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT The modifications to the calling numbers are produced by analysing the routing table. Here a route is searched for, that would enable callback to the current call. The number replacements for this route would then be used in reverse order. This automatic correction of the calling numbers is made according to the CGPN maps specified for ISDN interfaces or gateways, if available.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT If you delete the "CGPN Mappings", make absolutely certain that you clear the "Verify CGPN" check box, since otherwise no calling number at all would be allowed, making the Map ineffective. 8.2.4 Changing the calling party number for specific routes In some case it can be useful to modify the calling party numbers for calls routed with the aid of specific Maps.
Installation and Operation Manual ISDN – VoIP Gateway 8.2.7 Call forwarding TD 92326GB DRAFT It can make sense to define several routes for calls from the same call source with the same dial prefix. The gateway's routing process always uses the first suitable route. If a connection cannot be established using this route however, a further attempt can be made using another route. Various types of call forwarding can be implemented in this way.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT 47 Resources unavailable, unspecified 49 Quality of service unavailable 8.2.8 Call sequences Routes with the call destination "TRY" are a special case. If this type of route is used to switch calls, the call number is first replaced and the result is then used to search for normal routes. If the call can't be successfully switched in this way a further "TRY" route is subsequently searched for.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT A list of the defined reasons for rejecting calls can be found in Appendix B. The value specified in the “Error code (decimal)” column must be used. Figure 36. Rejecting calls 8.2.10 Enforcing en-bloc dialling Since your gateway supports continuous digit-by-digit suffix dialling, no specific dial digit is required to complete the dialled number. This behaviour resembles that of customary PBXs.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT performed even though a connection is treated as a voice connection. This can be the case, for example, with modem connections. You can suppress echo compensation by checking the "Disable echo canceler" check box in the relevant "Map" entry. 8.2.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT The table above shows the number of digits required. Complete bytes of the address have to be dialled in groups of three, even if less than 8 bits are required, according to the subnet mask configured. Leading zeroes must also be dialled. Assuming there is a group of VoIP devices defined by the network address 195.226.104.128 and the subnet mask is 255.255.255.128. The addresses 195.226.104.129 to 195.226.104.254 are thus accessible.
Installation and Operation Manual ISDN – VoIP Gateway TD 92326GB DRAFT Due to this procedure, the called number of a call being switched will be checked twice. The first time when searching for a route appropriate for the call, and the second time when searching for an appropriate alias within the "VoIP Interfaces" definition. It is therefore possible, and normal, to configure routes of this kind very simply using empty "Map" entries.
