Hello. I'm trying to set-up a system with a cisco pstn-gw and cisco-ip-phones and Messenger as UA:s. I want every users clients to ring if someone is calling, either if it's by using sip:NUMBER@domain or sip:USERNAME@domain. I.e. User 1: External phone-number 12345 Internal phone-number 2345@domain (cisco-phone registers as this) Messenger joe@domain So, if a call comes in via the pstn-gw i want the Cisco-phone and the Messenger to be INVITED. I have solved this by adding 12345@domain as an alias for joe@domain. Now, the problem, if i from the inside is calling 2345 from another phone (say 2346) i want both the phone and the Messenger to be INVITED. And if i'm inviting joe@domain through another messenger i also want the phone 2345 to be invited. How is this solved best? I have tried to add perm usrloc entries for joe@domain to 2345@domain and for 2345@domain to joe@domain. This almost seems to be working, but if i'm calling from the outside and hang-up before answering, the cisco-phone starts to ring again :/ Like it is getting invited all over again. I hope someone understands the problem, this should be rather normal (if someone is calling i want to be invited on all my devices...). Johan
