[SR-Users] Confusion about TCP worker ports

[Noah Mehl]

Alex,

No dice.

So now my question is what is the correct way to fix the Via?

If this is the original:

Via: SIP/2.0/TCP 1.1.1.1;branch=z9hG4bKd408.3f53e940ccb20c1033df4b3a8ebd8a34.0;i=1

Then do I update the port like this:

Via: SIP/2.0/TCP 1.1.1.1:33940;branch=z9hG4bKd408.3f53e940ccb20c1033df4b3a8ebd8a34.0;i=1

Or should I use an rport tag:

Via: SIP/2.0/TCP 1.1.1.1;branch=z9hG4bKd408.3f53e940ccb20c1033df4b3a8ebd8a34.0;i=1;rport=33940

Thanks!
