With late-negotiation the offer/answer model still applies. They should be sending you an SDP in the ACK to your 200 OK. They aren't. Their stuff is broken.

Hi,
one of my ITSP is using Cisco 2811 (IOS 12.4) as H.323 to SIP gateway for SIP trunk to my Freeswitch. I noticed that it sends INVITE message without SDP, and then Freeswitch terminates the call. I tried using 3pcc parameter as "proxy" and as "true", but no avail.
Is this expected behavior, and could I fix it somehow?
Here's SIP trace:
