Here is my system
Whenever I go to PJSIP Settings and click SAVE (even if I did not change something) and then click to reload the settings, there sometimes is an error in the next call. The system tries to
0x7fb780175020 – Strict RTP learning complete - Locking on source address 18.104.22.168:35422
0x7fb780028430 – Strict RTP learning complete - Locking on source address 22.214.171.124:5742
When this is coming up the system is muted on the first about 5 seconds.
2 or 3 times later the systerm dooes not try to learn and switches to the source address immediately. The muting is then not there.
