CS Interface Configuration 241
Example: Configure Direct Call Signaling on ISoIP interface
The following example shows how to configure 'direct call signaling' in an ISoIP interface by
specifying the remote IP address
SN> enable
SN# configure
SN(cfg)# context cs
SN(ctx-cs)[switch]# interface isoip AccessGateway
SN(if-isoip)[AccessG~]# remoteip 192.195.123.64
SN(if-isoip)[AccessG~]#
25.7 Specify the Port Address on VoIP interfaces
ISoIP and the Q.931 tunneling in H.323 can support ISDN services which use D-channel broadcast
messages, such as call back and call waiting services. These features are related to physical ports on
the remote gateway and not to a specific called party number.
In conventional voice circuits a D-channel message always reaches its destination, because the
destination is always connected directly with a wire to the switch (e.g. PSTN). In VoIP networks a
directly hard wired connection does not exist. Therefore a virtual tunnel is specified over the IP
network in which the physical ports are to be virtually connected. The virtual tunnel is realized by
assigning an identical port address to two VoIP interfaces. Likewise you have to configure 'direct call
routing' as described above between the VoIP interfaces and the physical port. For more explanation
refer to Figure 25-3.
Note: If you use this feature on a H.323 interface you have also to enable Q.931 tunneling as
described in more detail in Chapter 22 , “ DHCP Configuration ”.
Note: If no port address is specified for an interface, all calls with no port address are routed to that
interface. If a call has a port address which is not specified on a interface, the call will be rejected.
