Hello List Members,
Following is the scenario on which my question is based:
1> UAC-1 sends a REGISTER request using UDP from source port 20,000 to UAS-2 at
destination port 5060.
2> UAS-2 responds back with a 200 OK to above request from UDP source port
30,000 to destination port 20,000.
Considering the behavior of UAS-2, my question is: whether any SIP standard
suggests guidelines on whether it is advisable to send out responses from a UDP
port which is different from the one on which the request was received? RFC
3261 - 18.2.2 Sending Responses only talks about the destination the response
needs to be sent to, however nothing about the source.
Thanks and Regards,
Amit Ahuja
