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