[OpenSIPS-Users] insert 183 Progress with SDP in call dialog

[Dani Popa]

Hi again,

Can how can insert from opensips, without any other pbx, b2b ..., 183
Progress with sdp.  The ideea is, that sometime i need to insert in media
stream at begining, some audio, using rtpproxy and for this i should have
sdp and rtpproxy already used in call.  As application, for example i want
to change the ringback tone with opensips and rtpproxy from clasic ringing
to some music or message.
Thanks in advance for those who will tell me that opensips is sip proxy and
has nothing to do with relayed media.

the call trace case is next one:

(A)invite       ->opensips    ->invite(B)
(A)trying       <-opensips   <-trying(B)
(A)ringing     <-opensips   <-ringing(B)
(A)progress  <-opensips
(A)200ok      <-opensips   <-200OK(B)
(A) ACK       ->opensips   ->ACK(B)
