Hi;
You can check RFC 3725 for 3PCC usage of re-INVITE with no SDP.
In some 3PCC scenarios, when Media has to be switched between legs,
re-INVITE with no SDP is used to start the media switching process.
The expected response is a response with SDP listing all the suported
media types/codecs to be presented to the other leg, and start a re
negotiation of media.

Hi Everyone,
Is there any particular semantic meaning to a re-INVITE with no SDP?
How should a request like this be responded to?
