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.
