Hi List, I do have this setup: User has one deskphone and one portable (IP DECT) phone. Both phones have the same extention number and multiple registrations is set in the sip config This is the situation: If a user is on one of the phones and a second call comes in both phones will ring. This is the wanted situation: If a user is on one of the phones and a second call comes in a USER BUSY signal has to be send back I know you can use limit for this, but im not sure how to configure it on incoming calls when a user has 2 phones registered on the same extention number.
