What specs do I need to support 10 concurrent calls?

If I wanted to build an asterisk box to support 10 concurrent calls, how much memory and CPU do I need?

And what T1 card would I go with?


10 concurrent calls, even using low-bitrate codecs, is something that can be handled by almost any x86 platform.

Regarding T1 interface cards, for 10 concurrent calls, you can handle that across a single T1, so a one-port card would do just fine. You’d want to determine the bus you needed (PCI or PCI-Express).
