Hi
Sending your media capabilities in ACK is not Correct. You should
reject the Offer being made in 200OK(ie setting the ports in media streams
to Zero).
Subsequently you could send a BYE to terminate the dialog or could send a
Re-Invite
with changed SDP.

In ACK UAC will send its media capabilities.
Now both entities know each other's capabilities. If they cann't
communicate using the media they support ,any one of them can send BYE
request.
