Figure 43 shows a call set up from the A-party on the left to the B-party on the right. The call is routed from
the phone on the left-hand side over the ISDN interface directly to an H.323 interface. Once it has passed the
IP context and the IP network, the other SmartNode—from the H.323 interface to the ISDN interface and
then over the BRI port to the B-party phone—routes the call.
Note
Because call routing occurs only in the CS context, in future figures the con-
text IP is omitted. For configuring call routing you have to create the CS
interfaces and the call router tables as described in the chapters below. For
simple call routing directly from one interface to another you can even omit
router tables.
Creating and configuring CS interfaces
Multiple instances of CS contexts are supported. The name of the default instance is switch. The name and
number of CS interfaces depends on your own configuration. The interfaces on the CS context represent logi-
cal connections to other equipment or networks. CS interfaces are used as source and destination in the call
router. VoIP CS interfaces are bound to a gateway. Telephony ports are bound to respective interfaces.
Interface names can be any arbitrary string with a maximum of 25 characters. For ease of identification, the
interface type can be a part of the name. For examples and information on how to create CS interfaces, refer to
chapter 27, "CS interface configuration"

Specify call routing

As mentioned previously, for basic call routing you can omit creating call router tables. SmartWare offers two
levels of call routing:
• Basic interface routing
• Advanced call routing
