The missing branch parameter and the ACK sip:ip:port URI scheme makes me think this is an RFC 2543 (obsolete) vs. RFC 3261 issue. It sounds like your AS5300 is speaking 2543. This is not a problem when it speaks directly to the PBX because the PBX's UAS behaves in a backward-compatible way, but may be a problem when routed through the proxy.
I think it should work also via the proxy without problems. loose_route() should detect the strict-router (as there is no lr parameter in topmost Route header) and do proper routing.
