asterisk users - Oct 2003 - 16xE1 solution based on *

We are looking to utilise Digiums QuadxE1 cards for one of our European
customer, he is looking for
16xE1. Carrier has no VOIP support currently, so we need to organize by ourslef
VOIP-TDM interface, to get them connected to our network.  Idea is to try
Digium/Asterisk solution.

It will be some kind of VOIP gateway application, call from PSTN will come to
Asterisk via Quad E1 and will be forwarded to our centralized Nextone switch  to
handle digits manipulation , routing and termination.
I am curious how big server should be to handle 4 QuadxE1 of traffic. Definately
it is not good idea to put all cards into one box and to have one point of
failure. So I was thinking about 2 QuadE1 cards in each box.
Does anyone has experience with real time traffic on such volumes ?  What is
your experience? What kind of hardware do you run ?

Also how long usually takes to receive Quad port card from Digium, do they have
usualy csuch cards in stock ?

Regards,
Alexander

We opera dual E400p (single P4, 3,0 Ghz) and dual TE410p boxes (dual
Xeon, 2,4 Ghz). Both installations can handle 240 concurrent calls.
However, I heard recoding voice streams has quite some impact. So be
careful about your application.
