How Many Lines With My Configuration

[Guest Dan Schramm]

I plan to purchase a 48 line license for a business I am launching.

 

Right now I am finishing upgrading a 4u industrial server that I purchased.

I am going to use this system for development with a Dialogic D41ESC board and then add one or two T1 ISDN boards for the actual system.

 

I am curious how many lines I could handle before I would have to change the system to a dual Xeon.

 

Currently Dual 500mhz Celerons in a 20 slot passive ISA/PCI backplane with an 80 gig IDE hard drive. 512 megs now. Running Windows 2000 Advanced Server.

 

The launch system will have 1 gig of memory and SATA II Raid Controller for external drives. It will have 4 250 gig SATA drives. The IDE will have the system and applications. All the voice files will be on the serial ata drives. The voice mail system is going to offer about 25 different services. The software will choose the application based upon the called number delivered with DID trucks over a ISDN PRI on a T1 span.

 

I am going to keep the D41esc and connect Dialogic Promptmaster phones to it so people within our office/retail location can access their voicemail and record their greetings without tying up telephone lines.

For 48 lines we'd usually recommend a 2GHz P4 (single CPU) with 1GB memory.

Have you had a look at the load test results posted here:

Thank you for the prompt reply.

 

I wanted to be sure I could handle the initial 24 lines but expect to expand to 48 lines fairly quickly. So, you are saying the system really couldn't do 48?

 

Does VG make use of dual cpus?

Dual 500mhz Celeron with 512MB RAM should be able to handle 24 lines - it really does however depend on the type of script you will be running.

 

You will have to monitor system performance as the system gets loaded up – if your scripts are complex then there is a chance you will see CPU utilization go over 50% on this system with 24 lines used, at which stage you should be looking into using a faster system.

 

There is no definitive guide to what CPU speed you’d need – it just depends on so many factors that most of the time on larger systems you’re reduced to a ‘try-it-and-see’ approach.

Main areas which chew up the system speed would be local databases and running complex VBScripts from within VoiceGuide. If you don't have either of those then I'd say you should be fine with Dual 500Mhz.

 

(Turning VoiceGuide logging off will save a fair bit of CPU time as well)
