Hi,
We have received a question of whether the MTU size of our system can be reduced (I have currently no idea about the reason). RFC 3261, 18.1.1, states that if a request size is within 200 bytes of the MTU size the request MUST be sent using a congestion controlled protocol, such as TCP, so I started to look for a way to tell the stack the MTU size, and when I couldn't find one I looked for some logic that would ensure the behaviour, but couldn't find that either.
Am I missing something, or is it intended to be the responsibility of our UAC code to check the size of a request (first encoding it, I guess) and set the transport method to TCP if necessary?
Rgds,
Mats
