RE: [reSIProcate] onConnected received and processed before 200OK sent
My 7960, for example, will not accept media immediately after sending the
INVITE. The RTP packets between the INVITE and the ACK received by the 7960
are ignored. This is a problem when streaming pre-recorded prompts to
clients as the beginning of the prompts are always cut off.
Would it be an issue to add a new handler for when the ACK is received? Any
other suggestions?
Thanks,
-Justin

Sending media at the same time or slightly before the 200 is normal. The
uac will already be ready to receive media as it described in its offer.
