Asterisk 13 +Yealink 900 sec duration limit


I am having endless problems with Asterisk 13 and Yealink phones. My calls have a 900 second duration limit and then disconnects.

I have gone through my dial plan and nothing indicates to a duration limit.
I have check the yealink configuration file and also aren’t able to find a call duration limit.

Any suggestion as to the cause of the problem?


900 seconds would be typical of a problem with SIP session timers. Try setting them to refuse.

Thank you, I am busy testing now:
