Is there any SIP interface to contact MSN Messenger buddy or contact

Question

Hello,

I am working in a Telecom Service provider company. Actually we would like to know Is Microsoft providing
any SIP(Session Initial protocol) gateway or software or any APIs or any SIP interface, so that converts SIP messages to MSN
protocol & vice versa for voice calls. so any SIP device can make voice call to MSN buddy and the same way MSN buddy or contact
can make voice call to any SIP device.

Answer 1

Hi,

Thanks for you interest in the Windows Live Messenger Developer APIs.  Unfortunately, we do not provide any SIP APIs or interfaces into the Windows Live Messenger Service for voice calling today.

Thanks,
Kitty

Hi,


How about for SIP Instant Message?
Is there any SIP API to send/receive instant message, and presence?


Thanks
