Hi. I’m having some troubles after I upgraded from asterisk 1.8 to 11.17 version. What’s happening is that between the 180 Ringing, and the 200 OK (SDP) messages, exists a delay of almost 15-16 seconds, causing the audio to start being listened in the calling party, a couple seconds after it started to be played in the called party. This problem occurs only when I’m calling a cellphone, and the call is sent to mailbox. Here’s the call flow where you can see what I’m talking about.
Any other info will be provided as needed.
