Currently using 12.7.5-1805-3.sng7 / 14.0.3.6. FreePBX has a trunk connected to a Skype for Business 2015 standard server and has been functioning without difficulty since installation.
After a yum update, which upgraded Asterisk 15 from 15.2.2-1 to 15.4.1-1, call flow has been interrupted because of an unknown peer error. Downgrading Asterisk to 14.4.0-1 gives the same error. Downgrading again to the original 15.2.2-1 resolves the issue (after a fwconsole restart).
Calls from Skype for Business Server -> FreePBX -> SIP Provider are interrupted, but calls from SIP Provider -> FreePBX -> Skype for Business Server continue to work.
The Asterisk full log is below, as is the trunk configuration (which has been in use since before Asterisk 1.8 / FreePBX 5.211.65 without any issues). I’ve reviewed the changes listed at https://www.asterisk.org/downloads/asterisk-news/asterisk-154-now-available-0, but ashamedly cannot figure out which change has caused this issue. Can anyone point me towards a fix? Again, the only change was the Asterisk update from 15…2 to 15.4. Thanks.
