Just testing for now, no production traffic. Trying to find the breaking point. The reason for the questions are because I'm testing FS and after a certain point I am getting very high PDD, more than 6 seconds. Per the CDR's it takes about 6 seconds from start time in CDR Inbound to CDR outbound. I have tried 1 to 10 profiles to see if that makes a difference but it doesn't and 1 to 4 consoles running one profile each still no difference. Any idea why the CDR's should show it would take 6 seconds to get from start of inbound to start of outbound?

Now the RTP @ 1000 calls on the other hand assuming G711 at 20ms ptime. And assuming 1 leg calls originating from a dialer would generate 80megabits of RTP (at the IP layer even more on the wire), and approx 50K PPS. Assuming 2 leg'd calls bridging media 160megabit and 100K PPS of just RTP... But then we have to extrapolate peak concurrent from 1000 CPS... Assuming dialer traffic again, 75% ASR and 20 second ACD, and lets assume the 25% are just hard failed for the calculation (no early media on these) that gives us 750 new calls/sec and over the course of 20 seconds we accumulate 15,000 concurrent calls.. So lets take that and extrapolate bandwidth and PPS requirements for single leg'd calls of 1.43Gig/sec (on the wire) and 750K PPS so that's going to exceed the bandwidth of a GIG-E connection so you'd have to break this into 2 RTP endpoints in sofia, and make sure you switches/routers could handle the PPS loads. Double that to 2 leg calls and you have 2.86G/sec of RTP (again on the wire including UDP, IP, ethernet framing over heads) and pushing 1.5million PPS. Here again this dictates at least 3 gig-e NICs on your FS box. Is this possible? I'm sure it is with the right hardware configuration... But lets step back a minute and really consider what is going on... You are now putting approx over $2000/hr of traffic on a very expensive box that can and will at some point fail. Why are you doing such a thing? You're better off limiting rates to sub 1000 CPS, (say 500CPS) deploying 3 boxes to handle the load in n+1 configuration, and if you lose a box you arent losing $2000+ in revenue and cranky customers while you repair/replace the now dead machine. Lets face it, you can purchase a colo a nice machine for say 200 to 300$/month (assuming bandwidth costs are the same as above so that's a wash instead of trying to cram it all on box that ends up costing you 1000/month by the time you pay for the hardware and colocation expenses for it.

Not sure why you make a distinction here between sessions and connected. To be clear you mean 5000 bridge calls correct? Since media is not an issue I think you can just start testing with sipp and bwm-ng to see what is what. 1000 calls per second is a very big number. Let us know how you make out.
