Calls not hanging up

Hello everybody,

I’m a bit new to Asterisk, but getting better as I go along :smile:

My problem is somewhat simple. When my users hang up a call, their phones will occasionally ring back claiming that there is a call on hold. This seems to happen with any type of call… Voicemail, internal-to-internal, or over a Zap trunk.

I’m not quite sure if there is a setting that I have missed somewhere either on the phones or in one of the .conf files - So I’m just posting to see if anybody else has had a similar problem with their Asterisk system

I can provide any information that is needed :smile:

Thanks much

I would go to sip.conf and set


Hope this will solve it.


Is there a Siemens phones???
