Hello all.
We started having issues with outbound calls with a SIP provider. This below is the call flow:
CUCM -> SIP Trunk -> Voice gateway -> SIP Trunk -> Provider
On the voice gateway, I'm getting a disconnect cause=47. Viewing the logs, it seems that CUCM and VG are able to negotiate the g711ulaw codec, but after this, I can't see the invite to the provider offering the codec.
Could anyone help in this case, please?
CUCM 192 168 1 10
VG 192.168.1.9

Please check if the connection to service provider is not down?

Your config is a total messup.
You have no dial-peer configured with SIP between the gateway and CUCM.
Your dial-peer is using H323. Therefore, the call probably fails.

There's a dial peer between CUCM and gateway, that shows as incoming dial-peer on the logs: Result=Success(0) after DP_MATCH_ORIGINATE; Incoming Dial-peer=105
Those SIP messages are also between CUCM and GW. I can see that outgoing dial-peer gets selected, but never see any SIP messages to the provider.
Dial-peer to provider is 702.

Are you using H.323 between CM and the SBC? Dial peer 105 is a H.323 dial peer.
