Hi Andrew,

Many thanks for the prompt response.

Unfortunately it's this bit I don't want:

"Note that this may cause undesirable effects, like ringing for 3 seconds that turns into a busy signal."

I wonder how you can avoid that? Consider this scenario:
You receive 180 w/o SDP from far end
You send 183 w/SDP ringing to your client
The far end now sends a 183 w/SDP that contains a busy signal?

What do you do there?
