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.

For subscribed MWI, under the peer definition, set subscribemwi=yes(I'm not
sure what the default is). For unsolicited MWI, set subscribemwi=no and in
the SPA3000's configuration, clear the 'Voice Mail Server' field.
Unsolicited MWI is basically where Asterisk will send an MWI notification
without the client asking for it. Most Cisco phones require this as they do
not have the ability to subscribe for MWI notifications.
