This relates a bit to my recent post, asking about servicing multiple lines. Implication is that asterisk can do that, but I am now concerned that there is no "uber function" that can allow a single person answer any line, for reasons of convenience or design. Problem is, this was understood, rightly or wrongly, to exist, in preliminary inquiries (not here) and is a part of a potential clients desire. Can someone enlighten me? joe

Thanks for the plug Aaron. :) We stuck OpenSER in between the phones and Asterisk, and pointed our phones towards the OpenSER boxes for SIP registrations and subscriptions. When OpenSER received a REGISTER or SUBSCRIBE message, it would use the send() command to forward the messages onto each Asterisk server. By doing that, ALL of our Asterisk servers had a copy of all sip registrations and subscriptions. It seemed to work pretty well, but for unrelated reasons, we dropped that approach.

The phone sends it's subscribe message to whatever server it's registered to, so only that server will know about it. I know D. Garstang has done a lot of painful work on multiple clustered asterisk servers attempting to do stuff like this with SER, but we haven't done anything to that extent yet. There are probably a number of code modifications we could make to replicate the information from server to server, but it seems like that would start to get somewhat unruly. -- Aaron Daniel Computer Systems Technician Sam Houston State University amdtech@shsu.edu (936) 294-4198 _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
