we are using IPCCE with CVP 3.1 H323, Gatekeeper, we are trying to connect to GSM through SIP protocol, the VG is doing the conversion from SIP to H323, when we do test call the self service(IVR) is working fine the problem occur when we try to send the call to agent or IP Phone(Lable) the signaling is ok and the phone is ringing but no RTP stream came through. although when we try to send the call dirctly to the call manager(IPT scenario) the RTP is ok.

attached is log file from the VB stating that

13:25:11 Trace: 00000073: H323: ReceivedInTCS::Current Call state is CWaitForOutConnect
13:25:11 Trace: 00000073: ERROR INTERNAL: Cannot receive ReceivedInTCS in this CallState CWaitForOutConnect : DNIS = 46111 : CID = 6fed1f4b-

hi luai,

1- you may need to check the voip dialpeer configuration on the voice ingress gateway,it must include codec type like :

dial-peer voice 1 voip
service default
destination-pattern 2...
session protocol sipv2
session target sip-server
dtmf-relay rtp-nte h245-signal h245-alphanumeric
codec g711ulaw
no vad

2- Binding to source interface and allowing connection between sip and h323 :

voice service voip
allow-connections sip to sip

allow-connections sip to h323

allow-connections h323 to sip

fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback none
h323 (or sip)
  bind control source-interface Loopback0
  bind media source-interface Loopback0
  rel1xx disable
  min-se 360
  header-passing

3-check before that that no network issue regarding rtp ports blocking between ingress gateway and the destinied ip phones ip adresses.

the RTP issue is solved out , it was a bug in the IP to IP router
