[Asterisk-Users] help Windows messenger configuaration

[someshwarak]

Hi,

I am trying to register windows messenger to Asterisk. My windows messenger
gets registered succesfully but I am continously getting a error response of
SIP 481 Call Leg/Transaction Does not exist to the NOTIFY sip message.

here is the SIP error response packet

Sip read:
SIP/2.0 481 Call Leg/Transaction Does Not Exist
Via: SIP/2.0/UDP 10.50.25.119:5060;branch=z9hG4bK286a047c
From: "Unknown" <sip:Unknown at 10.50.25.119:5060>;tag=as18fde308
To: <sip:10.50.25.25:6931> ;tag=2fc7d57b0537473d85b3be02644724a2
Call-ID: 03059683637d0da5003fcf7123d1838f at 10.50.25.119
CSeq: 102 NOTIFY
User-Agent: RTC/1.3
Content-Length: 0

1.Is there anyway I can stop this. Help will be very much appreciated.

2.Did Asterisk also supports IM. If yes how to configure my dial plan for
the same.

thanks,
Somesh
