CS Context Overview 223
Configure General CS settings
The following example configures the general CS parameters
SN>enable
SN#configure
SN(cfg)#system
SN(sys)#no bypass-mode
SN(sys)#clock-source 1 0
SN(sys)#synchronize-to-isdn-time
SN(sys)#ic voice 1
SN(ic-voice)[1]#pcm code E1
SN(ic-voice)[1]#pcm law-select aLaw
SN(ic-voice)[1]#exit
24.5 Configure Call Routing
Calls through a SmartNode can be routed according to a set of routing criteria. The entity that
manages call routing is called
Session Router . Calls are routed from one CS interface to another . The
Session Router determines the destination interface for every incoming call. It supports complex call
routing and number manipulation functions. See Chapter
26 , “ Session Router Configuration ”.
Call routing occurs in the context CS element between several CS interfaces. Accordingly a CS
context and two or more CS interfaces must be created. There are three types of CS interfaces: PSTN,
H.323 and ISoIP interface. The differences between the several interfaces are explained later.
As an example, Figure 24-3 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 left-hand phone over the PSTN interface directly to an ISoIP
interface. Once it has passed the IP context and the IP Network, the other SmartNode—from the
ISoIP interface to the PSTN interface and then over the ISDN port to the B-party phone—routs the
call.
Figure 24-3: Direct Call Routing from one SmartNode to another
Because call routing occurs only in the CS context, in future Figures the IP context is omitted. For
configuring call routing you have to create the CS interfaces and the Session Router tables as
described in the chapters below. For simple call routing directly from one interface to another you
can even omit creating Session Router tables.
