Hello, while moving from asterisk 12.3 to asterisk 12.6, I see the MWI support for voicemail has stopped working. If I check “sip show peer 104-DEVEL” on asterisk 12.3, I can clearly see the “Mailbox” option set, while on asterisk 12.6 it appears empty.

Is there anything to do more for having MWI to work on asterisk 12.6? I
just moved the configuration used for asterisk 12.3 to the one running asterisk 12.6
