after upgrade from Asterisk 11 to Asterisk 13.38.0(chan_sip)
(i know, <br>
its old. customer is very conservative...)<br>
<br>
i have problem with missing 180 Ringing<br>
<br>
flow is easy (PBX -> Asterisk -> SIP SBC)<br>
<br>
Asterisk 11<br>
PBX - Asterisk<br>
-> INVITE<br>
<- 100 Trying<br>
<- 183 Session Progress<br>
( <- RTP -> )<br>
<- 180 Ringing<br>
<- 200 OK<br>
<br>
Asterisk 13<br>
-> INVITE<br>
<- 100 Trying<br>
<- 183 Session Progress<br>
( <- RTP -> )<br>
<br>
__MISSING RINGING___<br>
<br>
<- 200 OK<br>
<br>
temporarily i solved problem with using "R" param<br>
<br>
R: Default: Indicate ringing to the calling party, even if
the called party<br>
isn't actually ringing. Allow interruption of the
ringback if early <br>
media<br>
is received on the channel.<br>
<br>
it changed to<br>
<br>
Asterisk 13 (Dial(${ARG1},300,R)<br>
-> INVITE<br>
<- 100 Trying<br>
<- 180 Ringing<br>
<- 183 Session Progress<br>
( <- RTP -> )<br>
<- 200 OK<br>
<br>
any ideas why Ringing is missing? any solutions?<br>

<div>Have you compared the signaling in both directions
between the two versions to see if there is a difference? </div>

<p>whats your goal with this question?</p>
<p>asking if there are some side effects in incoming call ? (SBC
-> Asterisk -> PBX)<br>
