[Asterisk-Users] extensions problem (SIP)

[Bisker, Scott (7805)]

In your SIP.conf set callwaiting = no.  This will work for single registrations.  If you have multiple call appearance on you phone, then it will just ring to the second line (e.g. Cisco 7960).  If you only have a single registration, then you should be fine.

It depends on your SIP device. Asterisk places the call to your SIP device regardless,
since by SIP protocol design the UA is not a "slave", it is free. So the SIP ua must
answer "busy" for Asterisk to understand that you're busy. If not, the call is placed
to you and Asterisk has no knowledge that you are busy. Check you SIp phone if you can
limit the number of concurrent calls.

There's some code in Asterisk chan_sip.c to limit the number of calls placed to
a SIP phone, but right now it's not working at all.
