Hi Greg

I feel kind of confused. 

As SIPp manual says, -tn option opens a different socket for each call.
For each socket there is a 3-way-handshakes ([SYN]-[SYN,ACK]-[ACK])

Making 5 calls I should see 5 TCP handshakes and not one....

Where do I go wrong?

You are correct. There is only 1 TCP stream but there are in fact 5
different call flows over that stream.

 

May want to change the bind to address and I believe the port number may
need to be different. Not sure what that.

Hi All!

I'm trying to establish 5 SIP over TCP calls (-m 5 -t t5) using my
SIPp-3.0.

How many 3-way-handshakes (e.g [SYN]-[SYN,ACK]-[ACK]) I should see
within the capture?

Currently I see only one. Shouldn't it be 5?

PS: capture is attached

 

Thanks in advance
