[Asterisk-Users] Problem with NOTIFY

[Mohammed Firdosh Nasim]

Hi,

Consider the scenario

Asterisk Version : 1.0.5

UA1 <=============> Asterisk Server (AS) <=============> UA2

UA1 & UA2 have successfully registered with AS (Asterisk Server).

Now UA1 sends SUBSCRIBE (for UA2) to AS & UA1 gets 200 OK to SUBSCRIBE.

AS sends NOTIFY with open status to UA1 for UA2.

Now if UA2 unregisters (REGISTER with expires = 0), then no NOTIFY is 

issued to UA1 about UA2. UA1 assumes UA2 as still in "open" status.

But AS *MUST* have sent NOTIFY with status "closed" to UA1. Why this is 

not happening? Is there any configuration problem? Are there any special
commands in asterisk to enable notifications like this??

Please do help in this regard

With regards
Firdosh
