[Asterisk-Users] Asterisk scalability?

[Scott Stingel]

Hi Roy-
I've done a lot of load testing with asterisk and TE410P's.

My guess, with no transcoding, is that you might be able to handle 8 E1's
max on the PSTN side absolute max (ie: 2 TE410P's).  This assumes you have a
fast processor.    If you're using T1's, scale these numbers up accordingly,
as there are fewer channels per span.

If this answer is lower than you might expect, consider that every byte of
data has to pass through the processor.  The 410's are capable of
bus-mastering, and so are an improvement over the T400P's, but still I think
you run into horsepower limitations. 

Regards
Scott

Hi

I plan to setup an asterisk box to function as a SIP gateway forwarding lots
of calls to/from a backend of several other asterisk boxes, each with a
TE410 card for PSTN connectivity.  It will only gateway the calls into the
PSTN gateways. No transcoding is planned - only plain ALAW. How many
concurrent calls would you think this can handle? I'm asked to plan a system
that can handle >1000 concurrent calls...

thanks for any input

regards

roy
