Hi
There is no recommendation for using exisiting TCP connection for in-dialog
Sip requests.
As MTU for PRACK/BYE can be smaller ,so can be send over UDP also .
But for TLS recommendation is there to reuse same connection ,even for
request coming from callee using alias in via .
Please explain more about what you are asserting for TLS. It looks wrong
to me, but I'm not sure I understand what you are trying to say.
Thanks,

Hi,
Consider following scenario - Proxy1 and Proxy2 are edge proxies that are
DNS resolvable from edge.test.com. DNS resolution does some load balancing
and dynamically changes priority of proxy1 and proxy2.
A client originates a session over TCP connection to proxy1 after having it
resolved as top priority outbound proxy from preconfigured edge.test.com
domain. Proxy 1 sends 200 Ok response with following Record-Route header:
Record-Route: <sip:edge.test.com;transport=tcp;lr>
Now client wants to send a reINVITE and instead of reusing the established
TCP connection to proxy1 it resolves edge.test.com over DNS again and this
time receives proxy2 as top priority outbound proxy. Having received proxy2
with highest priority than proxy1 client sends in-dialog request to proxy2
instead of reusing established TCP connection to proxy1.
Now is there any recommendation for the preferential use of established TCP
connection to the proxy1 given that it is resolvable from edge.test.com?
Thanks,
xaled
