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.
