[Santhosh Kumar]

Lots of profesionla tools are availble in the net. 
   
  If you go to google and search for " Instant Messanger Monitor " and search you will find good number of softwares. Buy what i found was yahoo was safe bet.

  Testing with Ethereal, I was mildly alarmed* to see that changes of presence information and instant messages from Windows Messenger are sent "clear" so that anyone monitoring the net can pick this information up. The same seems to be true of GoogleTalk.

Does anyone here have any opinion on whether Voipsa should concern itself with the security of Instant Messaging & Presence? After all, SIP itself contains a mechanism to support these (SIMPLE), in addition to the telephony signalling services. I should say that neither Messenger nor GoogleTalk are apparently using SIMPLE today, but I imagine that many VoIP devices of the future will support it.
