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@10.100.12.243 SIP/2.0 Via: SIP/2.0/UDP 10.100.12.201:5060;branch=z9hG4bK3265182e;rport From: sip:2411234567@10.100.12.201;tag=as4c9b430d To: sip:2411234567@10.100.12.243;tag=5f12665a9832ee3ded87f1b2346a96d7 Contact: <sip:2411234567@10.100.12.201> Call-ID: 5ec3933956b9e8affef44df8051b0236(a)10.100.12.243 CSeq: 102 NOTIFY User-Agent: Asterisk PBX Event: presence Content-Type: application/xpidf+xml Content-Length: 364 <?xml version="1.0"?> <!DOCTYPE presence PUBLIC "-//IETF//DTD RFCxxxx XPIDF 1.0//EN" "xpidf.dtd"> <presence> <presentity uri="sip:2411234567@10.100.12.243;method=SUBSCRIBE" /> <atom id="2411234567"> <address uri="sip:2411234567@10.100.12.201;user=ip" priority="0,800000"> <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...!

No. I don't think so. Correct. Asterisk. Asterisk behaves wrong here, however, it gives user's the needed functionality.
