We have a sip trunk coming into our company, from our GW we have a h323 trunk to the CM from our GW. CM we signal I believe using Jtpi to IPCC, once it hits IPCC we have a script which allows someone to DTMF in someone's ext, then be trasnferred to that person, the problem is this call leg (from IPCC to IP phone) does not have ringing or hold music, it is just silence. I have tested this internally and I receive ringing on this call leg. The only thing I can think of that is different is the MRG is different from the GW from my phone. Can someone comment on this, maybe point me in the right direction?
