Hi All,
If a SIP request gets larger in size i.e. more than or equal to 1300 bytes or
within 200 bytes of the known path MTU then its required to open a new TCP
connection for that request to send.
The 200 bytes cushion is provided at client side in order that the size of
response from the UAS is well taken care thus.So the UAS while sending the
response can use the same trnsport from which it received the request to send
the response.So UAS is never required to check the message size for switching
transport.UAS's transport selection is dictated by the UAC.
Please any body clear my doubt that if in some Invite Transactions the
response grows by more than 200 bytes when for the first time UAS sends the SDP
offer for example and how the situation is handled if the UAS received the
request from UDP?
Regards and Thanks
