[Asterisk-Users] Asterisk scalability?

[Roy Sigurd Karlsbakk]

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
