[Serusers] unsolicited NOTIFY messages from Asterisk

[Subashini C V - CTD, Chennai]

hi,
	Thanks a lot for the inputs..

i have few more queries:


The NOTIFY for my Message SUBSCRIBE message is like the below:

NOTIFY sip:2411234567 at 10.100.12.243 SIP/2.0
Via: SIP/2.0/UDP 10.100.12.201:5060;branch=z9hG4bK3265182e;rport
From: sip:2411234567 at 10.100.12.201;tag=as4c9b430d

<status status="open" />
<msnsubstatus substatus="online" />
</address>
</atom>
</presence>

Queries:

The Event header is set to "presence", even though the SUBSCRIBE event
header has the type as "message-summary".

And the content-type is "application/xpidf+xml" and the content is in xml,
even though i send the content type as 
"application/simple-message-summary" in the SUBSCRIBE message.

It seems, for any of the SUBSCRIBE message, Asterisk is sending a NOTIFY in
this format only... am i right..?

So, As of now i have changed the source code of the Asterisk to give the
"message-summary" event.

Is there any way to achieve these by configuration..? 
( But i dont find any sources to give the text format instead of the xml
formatted message. )

It will be helpful if i have your ideas...!

Thanks in advance,
Subashini

If you get them after a subscription they should be fine.
However, Asterisk sends them out as soon as you configure a mailbox in
sip.conf with or without a subscription which is in violation of
RFCs - however, supported by most of the phones.

No. I don't think so.

Correct.

Asterisk. 
Asterisk behaves wrong here, however, it gives user's the needed
functionality.
