Summary:                    Voicemail MWI - deleted messages are not notified to
the extension
Description: 
Hi, 

My SIP client (SPA 3000) supports MWI with SIP NOTIFY messages. 

When a voicemail is left on the extension, a SIP NOTIFY message is sent to
my SIP client and the MWI is received ok. This is good. 

But when I delete all Voicemail through GUI(AMPortal), SIP NOTIFY message
notifying that there is no voicemail left is not sent to the client. 
Normally , I expect to receie a SIP NOTIFY message as soon as my inbox is
empty. 
However, this does not happen when I delete voicemail through GUI. 
If I delete voicemail through phone, I receive the SIP NOTIFY message. 

I have the following lines in my voicemail.cfg:
pollmailboxes=yes
pollfreq=30

My Asterisk version is 1.6.0.10-FONCORE-r40
It is running on CentOS (Trixbox)

The problem occurs each time I delete messages from GUI.

ebroad,

Thank you very much.
The problem is solved by "subscribemwi=no" definition under the peer on
sip_additional.conf.

It's strange though to see that if no "subscribemwi" is set it defaults to
"subscribemwi=yes" 
is it possible to change this default behaviour to "no" ? 
(globally, I mean , not per peer.)

I think this default behaviour is somehow buggy.

It is also strange to see that if I set "subscribemwi=yes" or leave as
default , and set Asterisk IP address on SPA3000 "voice mail server" field,
spa 3000 subscribes for notification and Asterisk sends the notification,
however spa 3000 does not turn of MWI.
