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.

I have an SPA-2102 which displayed similar behavior, disabling the
subscription and using unsolicited MWI(which I had to use anyway for my
Cisco 7940's, as they don't subscribe) resolved the issue, notifications
are near instantaneous. Do you have subscribemwi=yes under the peer
definition?
