sipX bridge disconnects because when it sent an INVITE without SDP to
Sippy B2BUA, that entity also responded with a 200 OK without SDP. That
is uncompliance in Sippy part.

I have a new installation with a new SIP trunk provider. It seems
everything is working except transfer. sipx 4.4.
Incoming external come through SIP trunk to attendant
Hit 1 to transfer to conference bridge
When transfer starts, call is dropped.
This works find when a-party is internal.
The problem might be in the INVITE coming from the REFER :
"SIP","Request: INVITE sip:194.6.238.85:5061
<http://194.6.238.85:5061>, in-dialog"
causing them to answer with a 200 OK with no Contact header which
sipX does not like.
Can anyone see from the attached pcap why this is happening
