26 • CS context overview
•
We enable DTMF relay and specify codec G.723. (Refer to section
on page 300).
•
We define H.323 'direct call signaling'. (Refer to section
page 301).
Configuring general CS settings
First we set clock-source to ISDN port 2/3.
SN>enable
SN#configure
SN(cfg)#system
SN(sys)#clock-source 2 3
SN(sys)#exit
SN(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:
SN(cfg)#context cs
SN(ctx-cs)[switch]#interface isdn IF-PBX1
SN(if-pstn)[IF-PBX1]#route call dest-table TAB-CALLED-NUMBER
SN(if-pstn)[IF-PBX1]#exit
SN(ctx-cs)[switch]#interface isdn IF-PBX2
SN(if-pstn)[IF-PBX2]#route call dest-table TAB-CALLED-NUMBER
SN(if-pstn)[IF-PBX2]#exit
SN(ctx-cs)[switch]#interface isdn IF-PUBLIC-PSTN1
SN(if-pstn)[IF-PUBL~]#route call dest-table TAB-CALLED-NUMBER
SN(if-pstn)[IF-PUBL~]#exit
SN(ctx-cs)[switch]#interface isdn IF-PUBLIC-PSTN2
SN(if-pstn)[IF-PUBL~]#route call dest-table TAB-CALLED-NUMBER
SN(if-pstn)[IF-PUBL~]#exit
SN(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.
SN(ctx-cs)[switch]#interface h323 IF-COMPOFF-A
SN(if-h323)[IF-COMP~]#route call dest-table TAB-CALLED-NUMBER
SN(if-h323)[IF-COMP~]#remoteip 146.86.130.11
SN(if-h323)[IF-COMP~]#bind gateway h323
SN(if-h323)[IF-COMP~]#exit
SN(ctx-cs)[switch]#interface h323 IF-COMPOFF-B
SN(if-h323)[IF-COMP~]#route dest-table calledNumberRouting
SN(if-h323)[IF-COMP~]#remoteip 146.86.130.24
SN(if-h323)[IF-COMP~]#bind gateway h323
SN(if-h323)[IF-COMP~]#exit
SN(ctx-cs)[switch]#
