SIP to multiple CAS trunk groups on same T1 interface

[Anonymous]

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:

interface t1 0/4

  tdm-group 1 timeslots 1 speed 64

  tdm-group 2 timeslots 2 speed 64

  tdm-group 3 timeslots 3 speed 64

  tdm-group 4 timeslots 4 speed 64

  tdm-group 5 timeslots 5 speed 64

  tdm-group 6 timeslots 6 speed 64

  tdm-group 7 timeslots 7 speed 64

  tdm-group 8 timeslots 8 speed 64

  tdm-group 9 timeslots 9 speed 64

  tdm-group 10 timeslots 10 speed 64

  tdm-group 11 timeslots 11 speed 64

  tdm-group 12 timeslots 12 speed 64

  tdm-group 13 timeslots 13 speed 64

  tdm-group 14 timeslots 14 speed 64

  tdm-group 15 timeslots 15 speed 64

  tdm-group 16 timeslots 16 speed 64

  tdm-group 17 timeslots 17 speed 64

  tdm-group 18 timeslots 18 speed 64

  tdm-group 19 timeslots 19 speed 64

  tdm-group 20 timeslots 20 speed 64

  tdm-group 21 timeslots 21 speed 64

  tdm-group 22 timeslots 22 speed 64

  tdm-group 23 timeslots 23 speed 64

  tdm-group 24 timeslots 24 speed 64

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.

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:
