asterisk users - Jan 2021 - Sollicitated MWI not working

Hello,

I configured MWI with pjsip.

The aors section contains:

mailboxes = 101@

The endpoint section contains:

context = internal
mailboxes = 101@

The dialplan leaves the voicemail by:
exten => s-NOANSWER,2,VoiceMail(${vmbox}@|u)
or:
exten => s-BUSY,2,VoiceMail(${vmbox}@|b)

When I configure clients to use unsollicitated MWI, it works, but
there are quite long delays in status display. So I decided to try
sollicitated MWI, but I am reaching some difficulties.

The twinkle client simply freezes on configuration. By the log I can
see it receives 401 on subscribe and then freezes. The SPA525G2 phone
automatically disables Message Waiting feature.

I tried selectively disabling mailboxes commands in both endpoint
(unsolliciteted stopped to work) and aors section but none of them
worked. I tried to change mailboxes = 101@ to mailboxes = 101 but also
without success.

I am not sure about both asterisk and client configuration.

At asterisk side is it allowed to have mailboxes allowed in both
endpoint and aor section? What is the connert mailbox format? Should
it be specified with @ or is it ok without it? Should the context
after the @ be specified? If so whoch one? The same as context command
in the endpoint? So should I change it to 101 at internal? Since the
unsollicitated MWI is working I expect I could leave it as is. Am I
right?

At the phone side, what should be set up? I tried to set Message
Waiting to yes, setting my Voicemail Server to the same name as sip
registry server and I tried mailbox name without @ and with @. Both
without success.

Could you give me some advice how should I configure it correctly, please?

Will the sollicitated MWI help me to evercome the indication delay problem?

Thanks

Marek

You need to specify a context in the "mailboxes" lines, in the form of
101 at context. The context would depend on what you have configured in
voicemail.conf. As you have not provided that, I can not say what with
certainty. Specifying the context should resolve your issue with
unsolicited MWI taking time to update.
