As far as I understand how voicemail is integrated into Asterisk, it seems that SIP channels poll MWI directly from the filesystem. Is it possible (feasible?) to have something like : - a central voicemail server - which has an IAX peer with a mailbox= line with tens of VM boxes - this peer has itself tens of SIP phones connected to it. And it would alert the SIP phones when it receives MWI over the IAX channel from the central server. -- Nicolas Bougues Axialys Interactive
