Re: [reSIProcate] Problem with UAC sending ACK automatically

However, Bill's use case was where there was an offer in the INV and an

Or possibly even earlier:

"Once the offerer has sent the offer, it MUST be prepared to receive media..." (RFC 3264, section 5.1) (It goes on for a bit more than that, but it really boils down to that statement).

and will be send by the UAC(Bill's UA) once the 200 is recieved; what is
the motivation for delaying the ACK?

For sessions with SDP in the INVITE, ACKs are a transport issue, not an application issue. It makes no more sense to withhold an ACK under these circumstances than it does for an application to withhold a TCP ack.
