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

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?
It seems a issue relatedto your PSTN gateway. Does it occur with any UAS?
In 200 OK there is no public address in the Recorde-Route list.

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

In 200 OK there is no public address in the Recorde-Route list.
It shouldn't be a problem since the gateway seems to have an interface to that private network. In fact, note that the first INVITE from gateway goes to the private address of OpenSer:
U 8.21.8.24:5060 -> 192.168.2.10:5060 INVITE sip:1001@2.6.7.9 SIP/2.0. Via: SIP/2.0/UDP 8.21.8.24:5060;branch=z9hG4bK69c359bd;rport. From: "19195551212" sip:19195551212@8.21.8.24;tag=as6869d7f8. To: sip:1001@2.6.7.9. Contact: sip:19195551212@8.21.8.24.
We can only guess about the topology. My guess is that here is a router with a public address and that the node that is hosting openser does not have an interface on the public network. The router could be using port forwarding or it could be a NAT binding. Then it would _appear_ as if the message went directly from the public network to 192.168.2.10:5060 depending on your point of observation.
For INVITE we rely on the registrar for the public address. For ACK we rely on the RR list.
