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 -- Tomasz Radziszewski Senior Software Engineer Ericpol Telecom sp. z o.o.
