this is not a problem of missing SDP in your replies, there was a bug in
OXE sipmotor when registration
and options supervision are managed for the same gateway.
If needed I could provide more details by pm as it's OT for the Kamailio
community.

which kind of Alcatel PBX it is? I use OPTIONS with and without SDP in 200
without
problems since several years with Alcatel OmniPCX Enterprise systems.
It's strange as we also work with other Alcatel OXE and OXO with no
problems. In this exact case, the PBX performs SIP registration and
later sends periodic OPTIONS with "Accept: application/sdp". Since the
200 is replied by my proxy Kamailio, it has no SDP (of course) and the
Alcatel PBX ignores the reply and sends retransmissionts until it
decides that "the proxy is down".
If you need I could try to get the exact PBX model (and firmware).
