Asterisk Call Drop Issue

Asterisk Asterisk SIP
1

Hello Team,

We have a call-dropping issue on Asterisk 16.12.0.
I also see some warning messages on the asterisk CLI.

How can I check the call drops, loss, etc?
How can I check if the channels are not exceeded?

I would appreciate your help, I am not very good at asterisk.

Please advise.

Your logs do not show anything related to NAT or call drop issues. Instead, they indicate the presence of frame type ‘10’, which corresponds to comfort noise, a feature not supported by Asterisk.

3

Do you know about commands to check the drop calls?

How can I turn off the frame type 10 messages on asterisk CLI?

Thanks

To enable PJSIP logging, use the command ‘pjsip set logger on’. Regarding the message mentioned in an old post, starting with Asterisk 13.18.0, that message will be silenced and won’t be visible anymore

I have turned on sip set debug on, there is lots of messages, how can I find the issue?

Thanks

I’m unable to provide guidance on how to read and analyze a SIP trace, as it’s beyond my skillset. However, I’m confident that someone else will be able to assist with this task.

make sure to “set sip debug off” after you’ve checked your logs.
