Hi,


I am trying to configure an IPIPGW where one side is a CCM and the other side is an SBC (Session Border Controller).

I tried 2 scenarios:
1.a) CCM - H323 - IPIPGW - H323 - SBC - SIP PROXY - SIP END POINT
1.b) CCM - H323 - IPIPGW - H323 - SBC - PSTN GATEWAY
2.a) CCM - H323 - IPIPGW - SIP- SBC - SIP PROXY - SIP END POINT
2.b) CCM - H323 - IPIPGW - SIP- SBC - PSTN GATEWAY


Here is my results for each scenarios:
1.a) Ringback tone OK, audio both ways OK, Moh (Hold and Resume) OK
1.b) Ringback tone OK, audio both ways NOT OK (When PSTN phone picks up, remote IP phone still ringing).
2.a) Ringback tone OK, audio both ways OK, Moh NOT OK (No music when CCM puts on hold and unable to resume the call)
2.b) Ringback tone OK, audio both ways OK, Moh NOT OK (No music when CCM puts on hold and unable to resume the call)

I need to validate at least one scenario (both will be better) but i have tried many options and running out of ideas.
SIP is fine apart from Moh
H323 is fine with Moh with On-Net but not ok with PSTN


Any ideas would be greatly appreciated.
I can post the voice config i have so far.

Thank you.
