Jeff,
<br />
<br />Read my post. I got my calls working but I am not sure if it was a bug or something is just jacked up with my config and I am not following the RFCs the right way. I can go into more detail offline if you need. I hope to get some feedback on my post.

<br />> Do you have a SIP trace? I'm just wondering if we are having the same problem. Does the ACK that gets relayed to ifself on the other IP have the username missing in the RURI?

<br />> > Here's the scenario. An INVITE comes in the WAN side and is t_relay'd to the LAN side. The LAN-side UAS sends a 200 OK, and that is relayed back to the WAN-side UAC. So far, so good. Then the WAN-side UAC sends the ACK to the 200. Opensips relays this from its own WAN IP to its own LAN IP - I found it with ngrep on the lo interface. Eventually Opensips sends a 408 back to the UAC.

<br />> > I've verified with xlogs the ACK hits in the loose_route() portion of the config. It does hit t_relay, but it relays the message to itself on its 'other' IP. I've tried to look the extended debugs but I'm not finding anything telling. Unfortunately I don't have any experience with multiple interface configurations. I suspect it has something to do with the double Via lines added, one from each interface. Perhaps it's not detecting the second Via as its own? (Even if that were the case, I can't explain why it's not responding to itself on the lo interface.)
