Logging into the web interface Logging into the web interface The Cisco TelePresence ISDN Gateway (ISDN Gateway) web interface is used for administering the Cisco TelePresence ISDN GW 3241 and 3200 Series units and the ISDN GW MSE 8321 and ISDN GW MSE 8310 blades, monitoring the progress of active and completed calls, managing dial plans and users, and for obtaining event logging information for reference or for troubleshooting complex issues.
Failing to log into the web interface Failing to log into the web interface When connecting to the Cisco TelePresence ISDN Gateway web interface, you must log in so that the ISDN Gateway can associate the session with your configured user and a set of access privileges. The ISDN Gateway has a set of configured users, and each user has an ID and password that are used for logging in.
Failing to log into the web interface Getting started with the Cisco TelePresence ISDN Gateway Ensure you have correctly completed the physical setup of the Cisco TelePresence ISDN Gateway (ISDN Gateway) following the instructions in the Getting Started Guide that accompanied it. You must also ensure that your endpoints and MCU are correctly configured to operate with the ISDN Gateway. Before you can make calls using the ISDN Gateway, you need to complete its setup using the web interface as follows: 1.
Failing to log into the web interface f. Now go to Dial plan > ISDN to IP, and click Add rule. g. For Rule name, type in a name for the new rule. h. For Condition, select Match any called number. i. For Action, select Call this number and enter the IP address of your MCU. j. Leave the other values unchanged. Click Add rule to add the rule to the dial plan. For more information about dial plans, refer to Understanding the dial plan. Cisco TelePresence ISDN Gateway 2.
Making calls with the Cisco TelePresence ISDN Gateway Making calls with the Cisco TelePresence ISDN Gateway The Cisco TelePresence ISDN Gateway allows: users with ISDN endpoints to place calls to users with IP endpoints users with IP endpoints to place calls to users with ISDN endpoints When configured correctly, the ISDN Gateway is transparent to users; they will require minimal assistance and training to place calls through the ISDN Gateway successfully.
Using the auto attendant Using the auto attendant You can use the auto attendant on the Cisco TelePresence ISDN Gateway to enter the number you want to call directly from your endpoint. If you are calling from an IP endpoint, you should enter a phone number. If you are calling from an ISDN endpoint you should enter an IP address (optionally followed by an extension number or phone number).
Using the Cisco TelePresence ISDN Gateway for voice-only calls Using the Cisco TelePresence ISDN Gateway for voice-only calls The Cisco TelePresence ISDN Gateway can be used to forward voice-only IP calls to the ISDN network (the PSTN); likewise, it can be used to forward voice-only ISDN calls from the PSTN to IP telephones on the IP network.
Using the Cisco TelePresence ISDN Gateway for voice-only calls Dial plan configuration You can configure the dial plan to restrict particular called numbers to voice-only calls. In this way, you can configure the ISDN Gateway to allow particular outgoing/incoming ISDN calls to be videoconferencing calls. Using the dial plan therefore allows you greater flexibility (if you need it) than using the global settings on the ISDN settings page.
Using the Cisco TelePresence ISDN Gateway for voice-only calls Displaying ISDN port utilization For each ISDN port, you can view details of any port activity for each ISDN channel. To display ISDN port utilization details, go to ISDN > ISDN ports. A message shows the status of ISDN layers 1 (physical) and 2 (D-channel). The same information is shown in the ISDN Status page. Note that if the ISDN Gateway is in leased line mode, there will be no status for layer 2.
Displaying the ISDN calls list Displaying the ISDN calls list The ISDN Calls List displays both active calls and completed calls on the Cisco TelePresence ISDN Gateway together with their basic settings. The list enables you to disconnect active calls and to delete completed calls from the list. For active calls, you can display further details (see Displaying detailed call information). Active calls are those calls that are taking place now.
Displaying the ISDN calls list Displaying detailed call information Active calls are listed along with some basic details in the ISDN Calls List (see Displaying the ISDN Calls List). To view additional details about an active call, go to ISDN > ISDN Calls and click more for the call about which you want more information. On the Call details page, the call for which more details are provided is displayed with a number (example: "Call 15 details").
Displaying the ISDN calls list Finished: the call is disconnected (you might not see this state). Encryption This field tells you whether encryption is active and if so, whether all or only some of the media channels are encrypted. Channel bonding map Only for ISDN participants: The numbers of the ISDN channels that are in use for this call. Channel rate Only for ISDN participants: Whether or not restricted 56k mode is in use for the received (rx) and/or transmitted (tx) part of an ISDN call.
Understanding the dial plan Understanding the dial plan The Cisco TelePresence ISDN Gateway uses the dial plan to determine how to route calls between IP and ISDN networks. When the ISDN Gateway receives a request to initiate a new IP to ISDN or ISDN to IP call, it examines the called number (if available), and uses the dial plan to determine whether to reject the call, find out which number should be called to initiate the outgoing part of the call, and to check the allowed call bandwidth.
Understanding the dial plan o Restrict (56k): whether a call will use 56kbps.
Displaying and testing the dial plan Displaying and testing the dial plan The dial plan is actually made up of two, separate dial plans: one for IP to ISDN calls and one for ISDN to IP calls. Refer to the sections below for more information. To display or modify the IP to ISDN dial plan, go to Dial plan > IP to ISDN. To display or modify the ISDN to IP dial plan, go to Dial plan > ISDN to IP.
Displaying and testing the dial plan Action What will happen if this rule is invoked.
Displaying and testing the dial plan • N x 56kbps: the call is a video call using N x 56kbps (for legacy ISDN endpoints only) Ports The ISDN port(s) on which the call may be placed. Codecs Shows the choice made when adding the dial plan rule. One of Default, Custom or Safe. (See Adding and updating dial plan rules for more details.) UID The unique identifier for the dial plan rule. Each rule in the dial plan is assigned a unique ID number generated by the ISDN Gateway.
Adding dial plan rules Adding dial plan rules The options that are available to you when you are configuring dial plan rules depend on whether or not the Cisco TelePresence ISDN Gateway is in leased line mode. (Leased line mode is configured on the Settings > ISDN page.) Select the help topic that you need: Adding and updating dial plan rules (non-leased line mode) Adding dial plan rules in leased line mode Cisco TelePresence ISDN Gateway 2.
Adding and updating dial plan rules Adding and updating dial plan rules This page describes how to add rules to the dial plan. It also tells you how to update rules. Note that you may also find it helpful to refer to Example dial plan rules. Adding dial plan rules To add a dial plan rule: 1. Go to Dial Plan. If you want to add an o IP to ISDN rule, use the IP to ISDN page. o ISDN to IP rule, use the ISDN to IP page. 2. Click Add rule. 3. Type a name for the rule. 4.
Adding and updating dial plan rules To include any of the incoming called digits in the outgoing called number, enclose each substitution group in a set of parentheses. Note that if you want to include the complete number, you do not need to enclose the whole expression in parentheses. Example: to match any number starting with "678", then followed by three or four digits, and you want the final digits to form part of the called number, type the expression: 678 (DDDD?).
Adding and updating dial plan rules Example: for all calls matching the condition of "55 (DDDD)", set an action to call the MCU with name "my_mcu" and join the call to the conference with identifier that matches "(DDDD)". For this example, type the action of my_mcu ! 00 $1. In this case, an incoming call to "551234" will attempt to join conference with numeric identifier "001234" on the MCU with the name "my_mcu".
Adding and updating dial plan rules outgoing call to that of the incoming call. This means that if the encryption state changes on either the incoming or outgoing call, the ISDN Gateway will attempt to change the encryption state on the other side of the call.
Adding and updating dial plan rules Updating dial plan rules To update an existing dial plan rule: 1. Go to Dial plan and find the rule you want to modify. 2. Click on the number or name of the rule to view its details. 3. Modify the rule details using the information listed above in Adding dial plan rules to help you. 4. Click Update rule. You may wish to create a new rule very similar to an existing rule. To do this, find the existing rule and click on its name or number to view its details.
Adding and updating dial plan rules in leased line mode Adding and updating dial plan rules in leased line mode This page describes how to add rules to the dial plan when the Cisco TelePresence ISDN Gateway is in leased line mode. It also tells you how to update rules. When you use the ISDN Gateway in leased line mode, the options on the dial plan are different to those in ‘non leased line mode’.
Adding and updating dial plan rules in leased line mode * match zero or more times. For example, "5+" means " match at least one 5, but possibly more". "D*" means "match any digit, any number of times". D matches any digit as well as * and # Example: to match any number that starts with "01", has any amount of digits in the middle, and ends with "5", type 01 D* 5.
Adding and updating dial plan rules in leased line mode To call a specific extension, separate the number/address from the extension by typing an exclamation mark (!). Example: to call the Cisco TelePresence MCU with IP address "10.2.1.33", and try to join a conference with numeric identifier "00000", type 10.2.1.33 ! 00000 6.
Adding and updating dial plan rules in leased line mode 7. For Codecs allowed select an option from the drop-down list:
Example dial plan rules Example dial plan rules Use the examples on this page to help you configure your own dial plan rules: • Allocating bandwidth using rules for IP to ISDN calls • Allocating bandwidth using rules for ISDN to IP calls • Forwarding ISDN calls to an operator or a conference • Specifying voice-only IP to ISDN telephone calls • Setting up dial plans rules when using TCS-4 Note these examples do not apply if the Cisco TelePresence ISDN Gateway is in leased line mode.
Example dial plan rules 1 Called number matches "553 (DDDD)" Call this number "$1" Video with BONDING 192Kbps This rule allocates 192kbps (that is, three channels) to any call with prefix 553. The specified action means that the dial plan removes the prefix and dials the group of four characters (containing 0 through 9 and # and *) that match the four characters represented by "(DDDD)" in the condition.
Example dial plan rules # Condition Action Call type Bandwidth Description 0 Called number matches "D+ 0000" Call this number "10.2.1.10" Video with BONDING 384Kbps This rule catches any number ending in 0000 and forwards it to, for example an operator, at 10.2.1.10 1 Called number matches "D+(DDDD)" Call this number "10.2.1.20 ! $1" Video with BONDING 384Kbps This rule catches any set of four characters or more and tries to join a conference on the MCU at 10.2.1.
Example dial plan rules 1 Called number matches "99555" Call this number "01753 548333!555P,,888P " Telephone None This rule allows a caller to connect to a PIN protected audio conference on an audio bridge. In this example, the audio bridge will answer the call. After a two second pause the ISDN Gateway sends the DTMF tones for the conference ID (555); these are the digits after the exclamation mark (!) which indicates where the number to dial ends and the DTMF tones begin.
Example dial plan rules from a Polycom endpoint, replace the * with ## from LifeSize and Sony endpoints, replace the * with #. For other endpoints, please refer to the user manual. It is possible to send an alphanumeric H.323 ID as a TCS-4 extension from most endpoints. For example, you can dial 1234*MCU, where MCU is the registered H.323 ID with the gatekeeper (usually case sensitive). It is also possible to send an IP address as a TCS-4 extension from ISDN-capable Cisco TelePresence endpoints.
Example dial plan rules The first (D*) group matches the numbers before the Pound (hash) sign and the second (D*) group matches the number after the Pound sign. Therefore in the Call out number field, $1 will replace the first (D*) group, $2 will replace the second (D*) group after the # sign (the TCS-4 extension) and the ! sign will indicate to the second ISDN Gateway that the first part is an ISDN number and the second portion is the TCS-4 extension.
Example dial plan rules # Condition Action Maximum call bandwidth 0 Match calls incoming on port "1" leased line group "2" Call this number "10.2.1.12 ! 555"
Dial plan syntax Dial plan syntax This page describes the syntax that you can use when adding dial plans. Note: All IPv6 address fields in the ISDN Gateway require the IPv6 address to be enclosed in square brackets [ ]. Syntax for conditions (Called number matches) When you configure the Condition for a dial plan rule, you may want to specify a pattern for the called number rather than specifying any of: match any called number, no called number or the exact called number.
Dial plan syntax outgoing called number, enclose them in parentheses. Note that if you wish to include the complete number, you do not need to enclose the whole expression in parentheses. other digits, and you want the final digits to form part of the called number, type the expression: 678 (D*). This will match "6780000", "678123", "6789999" etc. but not "775000".
Dial plan syntax empty number, the call will be rejected; in the above example, an incoming call to 55 would result in an empty substitution. ! ! This delimiter is only for use in an "ISDN bridge between IP islands" when you want to use TCS-4 extensions. In this case use the ! before TCS-4 extension in the dial plan for the first ISDN Gateway so that it is passed to the second ISDN Gateway in a format recognized as a TCS-4 extension..
Displaying the built-in gatekeeper registration list Displaying the built-in gatekeeper registration list The Cisco TelePresence ISDN Gateway contains a built-in gatekeeper with which devices can register multiple IDs. IDs can be numbers, H.323 IDs (e.g. Fredsendpoint) or prefixes. Up to 25 devices can be registered without a feature key. Feature keys can be purchased to increase this number. Note: The ISDN Gateway can register with its own built-in gatekeeper.
Displaying the built-in gatekeeper registration list currently have registered. The builtin gatekeeper will then use the information received from the neighbor(s) to reply to the original request. Accept LRQs Configures the built-in gatekeeper to reply to LRQs from other gatekeepers. These requests can come from any gatekeeper which has the ISDN Gateway's built-in gatekeeper configured as one of its neighbors.
Displaying the built-in gatekeeper registration list Gatekeeper status The number of registered devices is shown in the format X / Y where Y is the number of registered devices that your built-in gatekeeper is licensed for.

Configuring IP routes settings Configuring IP routes settings You need to set up one or more routing settings to control how IP traffic flows in and out of the Cisco TelePresence ISDN Gateway. It is important that these settings are configured correctly, or you may be unable to make calls or access the web interface. To configure the route settings, go to Network > Routes.
Configuring IP routes settings IP routes configuration In this section you can control how IP packets should be directed out of the ISDN Gateway. You should only change this configuration if you have a good understanding of the topology of the network(s) to which the ISDN Gateway is connected. Configuration of routes is divided into two sections: addition of new routes, and the display and removal of existing routes.
Configuring IP routes settings Viewing and deleting existing IP routes Configured routes are listed below the Add IP route controls.
Configuring IP services Configuring IP services To configure IP services, go to Network > Services. Use this page to control the type of services that may be accessed via Ethernet Ports A and B. You might want to configure the services that are available on each port if you want to use one port for management and the other for calls, for example, by only allowing web access on Port B. The Cisco TelePresence ISDN Gateway does not allow IP to IP calls (calls between Ethernet ports).
Configuring IP services certificate and private key. However, you can upload a new private key and certificates if required. For more information about SSL certificates, refer to Configuring SSL certificates. If a port is disabled, this option will be unavailable. Incoming H.323 Enable/disable the ability to receive incoming calls to the ISDN Gateway using H.323 or change the port that is used for this service. Disabling this option will not prevent outgoing calls to H.
Configuring SNMP settings Configuring SNMP settings To configure monitoring using SNMP, go to Network > SNMP. The Cisco TelePresence ISDN Gateway sends out an SNMP trap when the device is shut down or started up. The SMNP page allows you to set various parameters; when you are satisfied with the settings, click Update SNMP settings.
Configuring SNMP settings Configured trap receivers Field Field description Usage tips Enable traps Select this check box to enable the ISDN Gateway to send traps. If you do not check this box, no traps will be sent. Enable authentication failure trap Select this check box to enable authentication failure traps. You cannot select this check box unless you have selected to Enable traps above.
Configuring QoS settings Configuring QoS settings To configure Quality of Service (QoS) on the ISDN Gateway for audio and video, go to Network > QoS. QoS is a term that refers to a network's ability to customize the treatment of specific classes of data. For example, QoS can be used to prioritize audio transmissions and video transmissions over HTTP traffic. These settings affect all audio and video packets to H.323 endpoints. All other packets are sent with a QoS of 0.
Configuring QoS settings Audio Six bit binary field for prioritizing audio data packets on the network. Video Six bit binary field for prioritizing video data packets on the network. Do not alter these settings unless you need to. ToS configuration ToS configuration represents a tradeoff between the abstract parameters of precedence, delay, throughput, and reliability. ToS uses six out of a possible eight bits. The ISDN Gateway allows you to set bits 0 to 5, and will place zeros for bits 6 and 7.
Network connectivity testing Network connectivity testing The Network connectivity page can be used for troubleshooting issues that arise because of problems in the network between the Cisco TelePresence ISDN Gateway and a remote video conferencing device being called (or a device from which a user is attempting to call the ISDN Gateway).
Configuring general ISDN settings Configuring general ISDN settings These settings are global settings, which affect the configuration of the Cisco TelePresence ISDN Gateway with regard to ISDN network type and options, and allowed call features. To access these settings, go to Settings > ISDN. Note that some ISDN configuration must be done on a port-by-port basis; see Configuring ISDN ports settings. Refer to the sections below for assistance configuring the general ISDN settings.
Configuring general ISDN settings find that outbound calls fail (and inbound calls succeed), then try disabling this setting Send calling number to ISDN network Select the appropriate setting. Some networks do not allow you to set this and the call will fail if you; in others, the call will only work if the caller's number is forwarded and the DN is set exactly right; and in most networks, the setting is completely ignored. Experiment and see which setting works best.
Configuring general ISDN settings Allow parallel dialing Parallel dialing allows all ISDN calls to be bonded to be dialed simultaneously. Enable parallel dialing if your ISDN endpoints support it. Since parallel dialing is not supported by all equipment, disabling parallel dialing may improve interoperability with legacy endpoints; however, call setup times for outgoing ISDN calls may increase slightly. This option does not affect incoming ISDN calls.
Configuring general ISDN settings or International. In such cases select this option to set the TON for outgoing ISDN calls to National or International as required. For International you must also specify the International prefix setting. specified in the International prefix field. If there is a match the call is International; otherwise the call is National. For example, assume that Specify national/international type of number is selected and International prefix is set to 011.
Configuring general ISDN settings Line length Line impedance Line coding Transmit pulse shape National bits (Sa4..Sa8) customer support, or if you are an experienced ISDN administrator. relevant only for E1 networks. Video NSF Telephone NSF These fields allow you to choose a value between 1 and 31, or to leave the Network Specific Facility disabled (which is the default behavior and the implied setting in previous releases of the ISDN Gateway).
Configuring general ISDN settings codecs allowed codecs that endpoints calling through the ISDN Gateway may select. Content allows a separate presentation stream alongside the video stream. themselves negotiate which content codecs to use during a call. Use these options if you wish to restrict the choices available. Note: The ISDN Gateway does not advertise content at bandwidths of 128kbps or lower. Cisco recommends a total call bandwidth of at least 384kbps for a video call with content.
Configuring ISDN ports settings Configuring ISDN ports settings The options that are available to you when you are configuring ISDN ports depend on whether or not the Cisco TelePresence ISDN Gateway is in leased line mode. (Leased line mode is configured on the Settings > ISDN page.
Configuring ISDN ports settings calls may arrive at any one of the ports with a shared directory number. Note that when receiving an incoming ISDN call, the gateway advertises the directory numbers of the ports selected in the dial plan. If no directory number is specified, it assumes the directory number of the nearest lower-numbered port.
Configuring ISDN ports settings Use Max if you are unsure of which value to use here or refer to your ISDN network provider. Also use Max if you may switch between E1 and T1/J1 modes. Channel search order Select whether free B-channels should be selected starting with the lownumbered channel and working towards the high-numbered channel, or the other way around.
Configuring ISDN ports settings match the settings on the switch. Configuring ISDN ports settings in leased line mode These settings affect the per-port ISDN configuration of the Cisco TelePresence ISDN Gateway when it is leased line mode. Use these settings to enable the ports and to configure leased line groups. To access these settings, go to Settings > ISDN ports.
Configuring H.323 gatekeeper settings Configuring H.323 gatekeeper settings You can configure the Cisco TelePresence ISDN Gateway to use a gatekeeper, which can make it easier for end-users to make calls using directory numbers rather than requiring them to know the IP address or host name of the ISDN Gateway. You can register the ISDN Gateway with an external gatekeeper or you can enable its own built-in gatekeeper. To configure gatekeeper settings, go to Settings > H.323.
Configuring H.323 gatekeeper settings H.323 gatekeeper address The network address of the gatekeeper to which ISDN Gateway registrations should be made. This can be specified either as a host name or as an IP address. This field will have no effect if H.323 Gatekeeper usage (see above) is set to Disabled. The gatekeeper can be either the built-in gatekeeper enabled on the Gatekeeper page (see Displaying the built-in gatekeeper registration list) or an external gatekeeper.
Configuring H.323 gatekeeper settings Send resource availability indications Select this option if you want the ISDN Gateway to inform the gatekeeper about its availability or non-availability. This information will be used by the gatekeeper when it is selecting where to place calls. There are two scenarios where you can use this feature: where multiple ISDN Gateways are registered with the same dial plan prefix on the same gatekeeper.
Configuring H.323 gatekeeper settings Gatekeeper status The ISDN Gateway also displays brief status information about any registered gatekeepers. Field Field description Usage tips H.323 gatekeeper status The status of the gatekeeper currently being used by the ISDN Gateway. One of: name resolved to : the ISDN Gateway has successfully validated the IP address of the gatekeeper.
Configuring H.323 gatekeeper settings list of 'alternates' Note that if the ISDN Gateway registers with an 'alternate' that does not itself supply a list of 'alternates', the ISDN Gateway will retain the original list and if it loses contact with the current gatekeeper, each one will be attempted from the top again as before. Number of active registrations This number refers to the H.323 ID and the dial plan prefix.
Configuring encryption settings Configuring encryption settings You can configure the Cisco TelePresence ISDN Gateway to encrypt the IP "leg", the ISDN leg or both legs of a call. The encryption technology that the ISDN Gateway uses is Advanced Encryption Standard (AES). To use encryption, you must have the Encryption feature key present on the ISDN Gateway. For information about installing feature keys, refer to Upgrading the firmware.
