Description:This report filed here at the direction of Andrew Nagy.

Component: Voicemail MWI when using Asterisk Master Branch

'##' = extension number

MWI operates properly when PJSIP endpoint is configured with: mailboxes=##@default

SIP NOTIFY:
Messages-Waiting: yes
Voice-Message: 1/0 (0/0)

MWI fails when PJSIP endpoint is configured with: mailboxes=##@device

SIP NOTIFY:
Messages-Waiting: no
Voice-Message: 0/0 (0/0)

This problem does not occur with Asterisk 16.0.0.

I am unable to replicate this. Please post the relevant endpoint configuration from pjsip.conf, and voicemail.conf.

Also what is the output from the following:
{noformat}
ls /var/spool/asterisk/voicemail/
{noformat}
and if the "device" directory exists then ('##' = extension number):
{noformat}
ls /var/spool/asterisk/voicemail/device/##/INBOX
{noformat}

Changing only 'mailboxes=12@device' to 'mailboxes=12@default', SIP NOTIFY messages change from:

Messages-Waiting: no
Voice-Message: 0/0 (0/0)

to

Messages-Waiting: yes
Voice-Message: 1/0 (0/0)

I believe this may be the result of a change that has gone into all branches, https://gerrit.asterisk.org/#/c/asterisk/+/10132/, so I've marked this as a blocker until we can determine otherwise.

Using the above configuration I was finally able to replicate. Note, to reproduce you may need to add a simlink under the voicemail directory of device->default (or make sure a device folder exists with the necessary info under it).

Also, using git bisect I was able to confirm that cdece3b63740091b3d8387df167ca0a24ede0ed1 - app_voicemail: Remove need to subscribe to stasis - introduced this bug (which is the one [~jcolp] listed above).

FreePBX creates a symlink:

root@FreePBX:~# ls -l /var/spool/asterisk/voicemail/device/*
lrwxrwxrwx 1 asterisk asterisk 40 Nov  7 13:56 /var/spool/asterisk/voicemail/device/12 -> /var/spool/asterisk/voicemail/default/12

After much deliberation we've determined that this is something FreePBX is going to fix in regards to Asterisk 16.

We're going to revert the asterisk change for now, then put it back in when FreePBX is ready.

I just read a comment of origin patch which removed subscription to stasis...
"Since polling is only required when changes are being made to
mailboxes outside of app_voicemail and since the number of mailboxes
that don't have any subscribers is likely to be very low, all
mailboxes are now polled instead of just the ones with subscribers."

Where did the assumption come from that "the number of mailboxes that don't have any subscribers is likely to be very low"?
Imagine there are two asterisk servers running at the same time as master/backup or
as load balancing for thousands of SIP endpoints.
The IMAP storage is used for voicemail.
If master/backup the all endpoints have MWI subscription only on master server.
So only master server should poll IMAP mailboxes.
If load balancing the half of the endpoints have MWI subscription on the first server the others on the second server.

Without subscription to stasis both servers will poll all IMAP mailboxes.

I think the best way is to be able to switch on/off of the subscription to stasis using global option of voicemail.conf.
And this option should be ON (old behavior) for asterisk version 13 or it breaks compatibility. And it should be documented in CHANGES.
