[asterisk-users] TCP port, VPN and resolving the cutting voice problem

> I know understand the latency due to the resending .. But if the link was
have a good speed internet, then resending will make a big latency? 

I think the point is that with TCP, congestion will create a vicious circle
of more congestion, while with UDP congestion is bad in itself, but doesn't
result in more congestion created by the original congestion.

That being said, isn't UDP sometimes looked at as being lower priority than
TCP by many routers out there and dropped first when congestion does occur?
That makes it a good reason to use TCP in some cases.
