Re: [Sipp-users] Different ports used

[Tomasz R. <tom...@er...>]

Hi,

You are using "-t un" (separate socket for each call). If sipp opens many 
socket, it must use different port for each one. You can't have two sockets 
on the same port and the same IP address.

If you want to use specified port, remove "-t un" (or change it to "-t u1" 
which is default). Then sipp will use one socket for all calls and the socket 
will have the port that you put in "-p" option.

Best regards
