Well, if the RTP library was actually needed for the RTP transmissions you'd expect you'd have gotten some sort of error....but I'm talking here as someone with lots of Linux experience but who is only just a user of SIPp, who has never tried to do RTP with it. > -> What would be the maximum number of calls the Windows port of SIPp can > -> handle? I'm sure that will depend on your processor and I/O speed just like it does on Linux, it's just that the same hardware gets you fewer calls-per-second under Windows/cygwin. > 2.

Another alternative might be IMS Bench SIPp, which I'm currently learning, which can handle multiple scenarios per SIPp instance, but which is based on SIPp 1.1. A second advantage of the IMS Bench is that it has a manager that can ramp up the CPS rate in steps until too many call failures (complete call failures or inadequate response time) start happening, and record the results of each step. Although...it's oriented toward putting a SIP proxy or other central service node under load test, and if you don't have such a node (which it sounds like you don't) then using the "raw" features of IMS Bench SIPp to set up the kind of tests you want may be more trouble than it is worth. It all depends on your goals and timetable :) > Does this sound a sensible way to test my Lan in terms of simultanous > bidirectional G711 calls? Well, speaking as someone who understands something about LANs but is not an expert, if you are trying to stress test your LAN infrastructure in the face of VOIP calls, I'd worry that a two point test, while a good place to start, might not be sufficient. Having multiple speakers hitting your switches or whatever would be a more realistic test than just two speakers going over a single pair of switch ports (unless that's what your production load is going to look like!). My thought is that the two point test might overstate or understate the actual LAN capacity depending on the exact characteristics of your hardware and software. --RDM ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Sipp-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/sipp-users
