The answer is staring us right on the face Tony. The INVITE is towards
sip:69143662@176.34.141.24 <mailto:sip%3A69143662@176.34.141.24> and not
the domain. The proxy thinks it's routing out so it uses the external
IP. Configure the calling UA to use domain.

This might seem off target, but help me understand how the UA is
communicating with the proxy...
First, I have to say the eyebeam UA is VERY old and trying to
troubleshoot against it is problematic to say the least.
Can you provide a sip trace with a single call instead of pcap? At the
ITSP the port is 18402, at the UA it is 30498. I think it would be
easier to follow and understand with a sip trace in this instance.

We have one system (4.4 in EC2) which uses sipxBridge and an other
similar one which uses unmanaged gateway.
Incoming INVITE to these two system show different behavior when
the INVITE goes from sipxProxy and further in to the system where
the UA is really our server on port 5560. Our server relays calls
out to mobile phones.
The first INVITE below is with sipxbridge (sdp removed) shows how
the INVITE uses the FQDN and the VIA uses internal IP of sipx
The second shows the INVITE use external IP of sipx and the VIA
also uses external IP of sipx. This propagates into the system and
causes problems on the final ACK as seen on in attached pcap in
line 76, this I believe stops media from being relayed.
