[Can it support 260 Extensions]

Yea, that is doable. You need a good server for that, something with a fast CPU (dual core).

 

In the TDM world it was easy to come up with hard numbers when DSP with fixed channels were used. Nowadays with everything being software this is a difficult task, having a calculator like Matt proposes is really hard. I sometimes say "how many emails can you send with your email server per second" to make it clear that throwing hard numbers is not very serious.

 

Thanks.

 

What impact does voice mail have? When I said we don't record I was thinking recording conversations not VM. We do have VM.

 

Thanks

There are installations with 1500 extensions. However, the call volume is low and also not all extensions are registered all the time. Registrations are not a big load for the system. The important question is how many calls you expect to happen at the same time and if they are just regular basic calls or if for example calls should be recorded.

 

So the answer is yes, having 260 extensions registered in no problem. The "but" is that you must look at the call volume.

 

164 is nonsense.

 

Thanks. The 164 number came from an "consultant" pushing Avaya. The 150 number is on the snom website so that is where that came from.

 

We expect about 50 active calls as an average high activity (60 would be peak). We do no recording at all. We do however have 20 employees in an ACD call queue that gets about 400 calls a day (over a 9 hour period) and our current wait time is around 60 to 90 seconds.

 

Would that sound reasonable for pbxnsip?

 

Thanks

Considering a Windows based PBX serving 240 users and 20 "other" type devices coming in on 48 SIP trunks from Global Crossing. I have read that the ideal number is under 164. ANyone using it for this many extensions? thoughts?

 

Thanks!
