Re: [OpenSER-Users] SIP Trunk doesn't response to 200OK with an ACK

In 200 OK there is no public address in the Recorde-Route list.

Hello,

Here's the results of an ngrep command. It is showing a situation where I make a call on the PSTN to a DID, which terminates on my SIP Trunk. OpenSER receives the INVITE, etc. and I answer with my SIP phone, my phone OKs to OpenSER, OpenSER OKs to the SIP Trunk, but the SIP Trunk never ACKS. What causes this?

Thanks,

Eric
