Similar issue here. Update went from 15.5.0 to 15.7.2 and afterwards Asterisk started hanging throughout the day. Had to restart Asterisk service to resolve. I did a downgrade to 15.5.0 and it seems to be back to normal.
Tried moving to 16 while I was troubleshooting, but wasn’t able to get Asterisk to start at all after switching versions. Will have to look into that when I have time to take down the server.
Yep, just used asterisk-version-switch. After it did it’s think, Asterisk wouldn’t load at all. Tried to restart it a few times, didn’t look to closely. Just used the same command again to go back to 15.
Update: The issue I was having is mentioned in the thread below, the fix resolved my issue and I was able to move to Asterisk 16
I have never had that happen. Since reporting this, I have switched one low use production system and one system currently being setup from Asterisk 15.5.0 to 16.2.1. Obviously not valid tests, but after having no phones multiple times on Monday, at two sites, I’m not going to switch those until Friday night.
Upgraded from asterisk 14 to asterisk 15 yesterday night, phone system went down (not even internal calls worked) about 12-13 hours after that. I’ve now switched to asterisk 16. Was perfectly stable on 14 before.

I have not used 13 in quite a while, and have no idea how stable it is. So I cannot recommend something I do not know. I know 15.5.0 was stable and so have been both versions of 16 I have used (16.0.0 and 16.2.1).
I would expect current 13 is likely stable, yes. Just I have not used it.
It’s LTS just like 16 is LTS. There is always that space of time when there are no Stable releases of Asterisk just two LTS releases. Asterisk 13 gets support and fixes until 2020 due to there being two Stable releases in a row (14 and 15) one was EOL’d in 2017 and the latter is SFO and due to be EOL this year. The only reason there is a 15.7.2 was due to a security flaw found in older versions of 15.x and it was updated since it’s still SFO.
15 hasn’t gotten any other fixes or updates since Oct 2018 while 13 and 16 continually have.
