Hi everyone.

First of all... great program! Congratulations.
I use Phoner for a very specific scenario: I use it as a phone dialer for my house alarm system 
Whener the alarm detects motion, it calls Phoner to ring my mobile.

Everything works great except for one small thing that is not exactly Phoner's fault: sometimes the alarm system sends 3 and 4 requests in a short period and the calls get in line in Phoner and  some get on hold. Now and then some calls go the SIP server warning on amount on concurrent calls and stay there forever. I have to kill the calls manually on Phoner's GUI.

My question is: is there any way I can limit Phoner's call to only one active call at once? Can I make it reject all calls when there is already one in place?

Thanks.

Regards,
Mike
