Activating CS context configuration 353
SmartWare Software Configuration Guide 31 • CS context overview
• We enable DTMF relay and specify codec G.723. (Refer to section “Configuring voice over IP parameters”
on page 347).
• We define H.323 direct call signaling. (Refer to section “Configuring an H.323 VoIP connection” on
page 348).
Configuring general CS settings
First we set clock-source to ISDN port 2/3.
node>enable
node#configure
node(cfg)#system
node(sys)#clock-source 2 3
node(sys)#exit
node(cfg)#
Configuring call routing
Next we create the ISDN interfaces and configure call routing. Each interface is configured to route all incom-
ing calls to the routing table TAB-CALLED-NUMBER. This table is part of the call router and configured
below:
node(cfg)#context cs
node(ctx-cs)[switch]#interface isdn IF-PBX1
node(if-pstn)[IF-PBX1]#route call dest-table TAB-CALLED-NUMBER
node(if-pstn)[IF-PBX1]#exit
node(ctx-cs)[switch]#interface isdn IF-PBX2
node(if-pstn)[IF-PBX2]#route call dest-table TAB-CALLED-NUMBER
node(if-pstn)[IF-PBX2]#exit
node(ctx-cs)[switch]#interface isdn IF-PUBLIC-PSTN1
node(if-pstn)[IF-PUBL~]#route call dest-table TAB-CALLED-NUMBER
node(if-pstn)[IF-PUBL~]#exit
node(ctx-cs)[switch]#interface isdn IF-PUBLIC-PSTN2
node(if-pstn)[IF-PUBL~]#route call dest-table TAB-CALLED-NUMBER
node(if-pstn)[IF-PUBL~]#exit
node(ctx-cs)[switch]#
In addition, we create the two H.323 interfaces and configure call routing, as well as the IP address of the
remote H.323 terminal, which is the IP address of the device in office A or office B, respectively.
node(ctx-cs)[switch]#interface h323 IF-COMPOFF-A
node(if-h323)[IF-COMP~]#route call dest-table TAB-CALLED-NUMBER
node(if-h323)[IF-COMP~]#remoteip 146.86.130.11
node(if-h323)[IF-COMP~]#bind gateway h323
node(if-h323)[IF-COMP~]#exit
node(ctx-cs)[switch]#interface h323 IF-COMPOFF-B
node(if-h323)[IF-COMP~]#route dest-table calledNumberRouting
node(if-h323)[IF-COMP~]#remoteip 146.86.130.24
node(if-h323)[IF-COMP~]#bind gateway h323
node(if-h323)[IF-COMP~]#exit
node(ctx-cs)[switch]#
