I do exactly that, here is a sample of one of my user/ext definitions, 110, note 2 things: MWI-Account and mailbox are set to 100. Multiple users point to the same mailbox. This lights the MWI on multiple phones and allows the phones to press the mailbox key to auto call mail and get the mail from 100 (the group mb). Worked on Linksys/Cisco and now works on our Yealink phones. BTW, this also sends the VM msg as an email to multiple iPhones. Hope this helps.

Hi,

You can try to force the SIP MWI request to monitor the group mailbox instead of the user's: https://wiki.freeswitch.org/wiki/Mod_voicemail#2._Force_MWI_Info_in_Sofia

Hi All,
I want to be able to ring a group of phones and then divert in a "group" mailbox and then when a message is left in the group mailbox, it illuminates the MWI of each member in the group.
Is that straight forward?

Thanks

Richard
