Summary:                    progressinband=yes send 180 and 183 together
Description: 
I set progressinband=yes on asterisk-1.4.13. Asterisk sent 180 Ringing and
183 Session Progress together, which causing the ringback tone broken.
Asterisk had sent 180 ringing first. Asterisk sent 183 when got inband
progress indication from pstn.

It's not possible to get rid of the 180 Ringing as you seem to need, but it
is perfectly acceptable to send 180 and then 183. The SIP implementation
should just accept the audio stream from the 183 Session Progress and stop
producing it's own ringing.
