Voicemail pjsip.conf File Changes
You can add the ability to enable the Message Waiting Indicator (MWI) lamp on SIP phones when there is a message in a mailbox. By default Asterisk will send SIP NOTIFY messages when a voicemail is left. Some phones need to subscribe to the MWI information. In that case you need to modify the AoRs section for the phone and add a mailboxes= section.
