Installation and Operation Manual VoIP Gateway 19 TD 92326GB Considerations on the Configuration of the Gatekeeper Interfaces The telephony infrastructure in the VoIP environment always consists of three different modules: VoIP end points, VoIP Gateways and Gatekeeper. • VoIP end points These are devices that implement the end points of telephone calls, for example the i75 VoWiFi handsets. • VoIP Gateways These are gateways to other telephony networks or technologies.
Installation and Operation Manual VoIP Gateway TD 92326GB 19.1 Understanding the VoIP Gateway's Gatekeeper What is a Gatekeeper in general? – A Gatekeeper/Registrar takes registrations from Endpoints (Gateways, Phones) – Thus the Gatekeeper is possible to route Calls to Endpoints without configuring their IP address. – Can determine what Endpoints are not available / not registered and so re-route without trying first to give the call to the not available / not registered Endpoint.
Installation and Operation Manual VoIP Gateway TD 92326GB The source and destination of the call do not necessarily have to use the same gatekeeper, figure 123 on page 135 shows the sequence of a call which is forwarded via two gatekeepers. The sequence of the call is the same for the destination and source as illustrated by figure 122 on page 133. The more complex infrastructure is fully concealed by the gatekeepers. Only two gatekeepers now have to be known to one another.
Installation and Operation Manual VoIP Gateway TD 92326GB and accessible if the ID is OK. Devices that log on to the gatekeeper using the RAS protocol are configured in “Gatekeeper client group mode”.

Installation and Operation Manual VoIP Gateway TD 92326GB PPP protocol (in the WAN) remains the same per packet, whilst the voice data quantity, and with it the data actually used, is reduced. The bandwidth actually required is therefore considerably higher (depending on the packet size) than the pure voice data bandwidth as specified in the table Voice encoding schemes on page 138.
Installation and Operation Manual VoIP Gateway TD 92326GB The values specified here are approximate values, as determining the bandwidth exactly depends upon a number of factors. Tip: The effective bandwidth required can vary according to conditions in the given environment. On the one hand, routers used in the transmission link can apply special compression techniques (RTP header compression) and thus reduce the required bandwidth.
Installation and Operation Manual VoIP Gateway TD 92326GB • If it is necessary to modify call number processing, then add CGPN Maps and make the entries, see 21 Considerations on the Configuration of Call Routing on page 144. • If calls from external gatekeepers are also to have access to the VoIP Gateway's ISDN interfaces, define the voice transmission parameters (see section 19.1.5 Voice Transmission on page 137). 19.
Installation and Operation Manual VoIP Gateway 20 TD 92326GB Different Usage of the VoIP Gateway 20.1 Dealing with the various ISDN address types Call numbers are always treated internally by the VoIP Gateway as unknown type of number. In ISDN however, there are various types of call numbers (see the table below) with the effect that call numbers are only ever interpreted in combination with their number types.
Installation and Operation Manual VoIP Gateway Incoming calling number International TD 92326GB Blank 00 Places the discriminating code 00 in front of international calling numbers This ensures that the calling number is displayed correctly for incoming calls of all number types. A typical application of CDPN mappings is the manipulation of the root number on pointto-point connections, for incoming calls.
Installation and Operation Manual VoIP Gateway 21 TD 92326GB Considerations on the Configuration of Call Routing Your VoIP Gateway's gatekeeper is responsible for call routing. It is controlled by “routes”. Note: These are voice routes, not to be mistaken with the data or IP routes. 21.1 Routes Each route defines a permitted path for a call, from the interface where the call arrives, to the interface from which the call departs.
Installation and Operation Manual VoIP Gateway TD 92326GB 21.2 Maps Of course, call switching often also depends on the call numbers dialled. That is why it is necessary to define the validity of routes for calls with certain destination numbers. This is done by attaching a so called Map entry to the route of each valid dial prefix.
Installation and Operation Manual VoIP Gateway TD 92326GB then, the current call will be switched to the interface specified in the destination field in the route of the Map or in the destination field of the Map. Figure 128. Map In the process, the called number is modified in such a way that the dial prefix in the “Number in” field is replaced by the sequence of digits in the “Number out” field.
Installation and Operation Manual VoIP Gateway TD 92326GB of the calling numbers is made according to the CGPN maps specified for ISDN interfaces or gateways, if available. Enable “Exclude from Auto-CGPN” check box if you want certain routes to be excluded from this process. 21.5 Selective Routes Depending on the Calling Number In certain cases it can be useful to restrict individual routes to particular calling numbers.
Installation and Operation Manual VoIP Gateway TD 92326GB In this case, make certain that the “Verify CGPN” check box is selected. Note also that during the execution of a route, the interpretation of calling numbers is always independent of the type of address (see section 20.1 Dealing with the various ISDN address types on page 142) with the effect that no address types can be specified here. 21.

Installation and Operation Manual VoIP Gateway TD 92326GB 21.12Enforce en-bloc dialling The VoIP Gateway supports continuous digit-by-digit suffix dialling and no specific dial digit is required to complete the dialled number. This behaviour resembles that of customary PBXs. The so called Overlapped sending is however not supported by all H.323-compatible devices. When a call is set up to such a gateway it will not be able to process the suffix dial code and the call will fail.
Installation and Operation Manual VoIP Gateway 22 TD 92326GB Definition of Operating Parameters 22.1 Setting the IP-interface parameters via DHCP Default, the VoIP Gateway tries to configure via DHCP each time it is switched on. The configuration mode without DHCP is activated however each time the reset button is pressed (refer here to section 22.2 Setting the IP-interface parameters without DHCP on page 152.

Installation and Operation Manual VoIP Gateway TD 92326GB 22.8 Dial tones The VoIP Gateway is able to generate call progress tones at the ISDN interfaces (dial tone, ring tone, busy tone). This is done for outgoing calls from the VoIP Gateway in the direction of the calling party, whenever the called party does not generate any dial tones of its own. Tip: Dial tones can be identified by the “inband information”, which is signalled by the called party.

Since the values are somewhat complicated, the configuration provides help editing to make correct entries for Central Europe and Great Britain: • If you select the value “Central Europe” in the “Load TZ-String for” field, then the TZ string will be entered in the “String” field for the Central European time zone.
Installation and Operation Manual VoIP Gateway TD 92326GB 22.10Call Pickup Calls for a subscriber can be picked up by other subscribers, provided they have not already been answered. To do this, you have to know the call number of the called subscriber or of a call group of which the subscriber is a member. A special function prefix must be set up in the PBX Application for this purpose. • Enter the desired prefix with which you would like to initiate the function in the Pickup prefix dialstring field.
Installation and Operation Manual VoIP Gateway 23 TD 92326GB The Virtual Interfaces TONE, TEST and HTTP The VoIP Gateway has three virtual interfaces implemented; TONE, TEST and HTTP. 23.1 The Public Dial Tone Interface “TONE” The TONE interface can be used as a destination for a call. If a call arrives at the TONE interface, it is not forwarded but the dial tone configured for the interface is played (the incoming call is acknowledged with SETUP_ACK and a media channel is set up).
