T1 CAS inbound dialing using H323

Does anyone have an example of a config of an IOS gateway for use with Call Manager 3.1.2 for inbound dialing through t1 cas. The number that outside callers will dial is a 1800 number. Once the call comes in it will need to be routed via operator extension within call manager. Any help would be much appreciated.

Re: T1 CAS inbound dialing using H323

you need to do a number expansion. it is configured in the general config leval. so for example if the telco is delievering 4 digits like 0034 then it would be.

num-exp 0034 0

dial-peer voice 4 voip

dest-pat 0

session target ipv4:x.x.x.x

so the first part of the number expansion what ever the telco is delivering the second part is the number of the operator it could be her 4 digits if you do not have a translations pattern in cm.

hope this helps.

I've done this with PLAR before. Ex:

dial-peer voice 100 voip

destination-pattern 0

session target ipv4:x.x.x.x

voice-port 1/0:0

connection plar 0
