Hi all,

We have a Asterisk 16 server running without any problem supporting WebRTC and SIP in which calls were working well.

But suddenly, faced issue in making calls and got the below errors.

Asterisk 16 is EOL. Upgrade to a supported version.

3

Additionally things don’t just stop working. Something changed. For example, was the libsrtp library updated?

4

Restarting the server fixed the issue.
Don’t know what fixed it.
any idea over it ?

Hi,

Asterisk 16 is running in Ubuntu 22.04. Calls were worked fine using WebRTC.
But today I noticed call gets terminated while answered immediately, getting below error.
SIP protocol calls also not working .

Network is unreachable and Unable to open file /var/log/asterisk//cdr-csv//Master.csv : No such file or directory

You have 2 problems here. Did tou check if network is working and if this file exist ?

yes network is reachable, that makes the call to work.
