This can be done with code changes to SIPp. On Linux, epoll() can be used to efficiently poll on a large number of sockets. We've done this and I mentioned it in the set of changes Intel is working on in the context of a possible implementation of the ETSI IMS Benchmark spec (see post from last-week on this topic if you're interested). We implemented one port per user and we use up to 25000 users (and hence ports) per SIPp process. Then virtual IP addresses can get you to even more users per system. We also streamlined a bit the processing loops to have better performance.

Michael, I don't know how to do this (or if it is even possible), but off the top of my head you may be able to somehow extend the per IP address code (-t ui) to do this if you can't find any other way. Charles Michael Hirschbichler <[EMAIL PROTECTED]> Sent by: [EMAIL PROTECTED] 04/23/2007 11:00 AM To [email protected] cc Subject [Sipp-users] Listen to more than one UDP-Socket? Hi! I want to use sipp in the current version to listen to more than one local UDP-Port. Is this possible in some way? Background: I register 1500 different user from the same host, but with different port-numbers in the "Contact:"- and the "Via:"-Header field. After registering, I create 1500 calls, one to each of these users. For this reason, I want sipp to listen to port 6050 to 7550 to answer these requests ...
