Here's the full conversation. Makes me wonder whether the ACK needs to go back to the same host that handled the INVITE or whether it should be returned to the host mentioned in "c=IN IP4 PROVIDERMEDIAIP" in the 200 OK.

You still gave the conversation in one side, towards the provider. You need to get the traffic from caller side as well, which is listening on 127.0.0.1, but it is important to see what that side sends and receives. You have to grab the traffic on lo interface as well.

Cheers,
