HI,
By default SIP uses port 5060 for incoming and outgoing messages. But In
some cases, I have seen, the incoming port used by server is 5060 but when
it sends outgoing packet, it uses Ephimeral port.
Could someone please explain me , why this Ephimeral ports being used ? and
what is it benifits
Anjan,
The use of the ephimeral port is not SIP specific but because of the TCP/IP
stack.
And even though the outgoing messages will be sent over an ephemeral port,
the message is prepared using the standard ports the SIP stack is listening
so subsequent requests and responses are able to reach ba
Thanks George.
But my concern is what is the benifit if server use Ephemeral port instead
of 5060 for outgoing port ?
Could you please explain bit more on this ?
Thanks,
Anjan

Anjan,
The reason behind this is to keep 5060 available for incoming traffic and
assign a dynamic/ephemeral port for outgoing traffic.
