SIP to multiple CAS trunk groups on same T1 interface

Jump to solution

Looking for a sample config for TA9xxe. Looking for a SIP to multiple CAS trunk groups. I found a sample config for SIP to Single CAS and a config for SIP to dual CAS (one on each interface) but not one where the CAS trunk groups are on the same interface and separated by DS-0's.

Hello Raul,

Thank you for posting to our forum.  I have a partial config that should be useful.  I used a TA 924e and t1 0/4 for the RBS trunk.  Please let me know if this is what you are looking for:

With this type of config each tdm group can have a unique caller id and DID on the voice side.  Let us know if you have any questions.

Re: SIP to multiple CAS trunk groups on same T1 interface

Thanks Geoff. I was close and your answer got me to where I needed to go. My config called for two CAS TG's, one with 10 DS-0's and the other with 14 DS-0's, both on T1 0/3. Not to confuse the issue but I also had an ISDN PRI on T1 0/4. Here's the shortened version of the 924-E config with registration and authentication working:
