No. Not sure what Microsoft Siren does, but to my knowledge you cannot decode it with G722.1 code.

Here are a couple links to other discussions of this:

Hi, Rick.

Could you tell me how you connect to the Communicator throw SIP? I mean ports and how does theSIPURI look like? Can I create P2P without server?

Igor.

Hi Igor,

I'm not aware of how to setup Communicator in a P2P mode. Everything I have done hasMicrosoft's Live Communication Server (LCS) in the middle. Communicator is an IM client that has ability to do voice, so the first thing it looks for is somewhere to login. I talked with a couple people around here, and P2P Communicator is not something we have done.

Below, I've included an example of a SIP INVITE with SIREN.

Hope this helps.

Enjoy,

Rick
