Anita, this card is a data card. It does not provide ISDN protocol. For 6000 calls, you should better find a telco that provides SIP trunking over Fast/GigaEthernet.

Hi

Please check out this product

Does it work on Freeswitch or Asterisk ? Do Telcos provide an E3 connection ?

One of our customers had an inquiry for terminating 6000 calls simultaneously. I want to do some homework before taking it further with him. If I use E1 lines, I will need 6000 / 30 = 200 E1 lines, which does not look feasible ?

Thanks for any input you may provide.

regards,

Anita Hall, Simmortel Voice.

That card only operates as an E3 or T3 data card. It is not channelised to work as a PSTN voice card. So, no, it doesn't work with Asterisk or Freeswitch - unless you are looking for IP connecion for VoIP. Sangoma used to talk about producing a channelised revision of the card, but it looks like the potential sales have never looked promising enough to make it happen. Digium used to have an E3/T3 card on their web site, but I assume they canned it. You don't hear anything about it now. I never found an E3/T3 card which is properly channelised to act as a PSTN interface for a package like Freeswitch or Asterisk. A lot of people will try to tell you that you really wouldn't want to handle so many calls in one box, but that is a rather odd thing to say these days. Servers are much faster than when Asterisk started, and the goal posts have moved. People handle this many VoIP calls on a single box these days. If suitable E3/T3 hardware were available, a modern server could be constructed to handle this number of PSTN calls. Steve

I would recommend you look at a provider who can give you SIP interconnect, or looking at a hardware media gateways which can support the TDM side of this equation and convert to SIP for your FreeSwitch server(s).
