Thanks for the information, I will look into both cisco and adtran see which would be helpful On Thu, Oct 15, 2009 at 4:09 PM, Alex Balashov abalas...@evaristesys.comwrote: David Backeberg wrote: On Thu, Oct 15, 2009 at 4:58 PM, David Backeberg dbackeb...@gmail.com wrote: There's no one-step solution I'm aware of.

[asterisk-users] DS3 capacity calls using asterisk
Hi All, We are trying to implement a DS3 capacity calls (672 concurrent calls) using asterisk server. I wanted to ask are there any compatible DS3 cards with asterisk? I tried searching a lot but could find DS3000P from digium but unable to get this product. Does anybody have any idea of having any DS3 card in asterisk box so as to handle around 600 calls?

It's a bit out of my league (300 is my biggest installation so far), but I'd suspect dedicated hardware like something from Cisco or a used Ascend TNT to take the DS3 in 1 side and spit SIP over Ethernet out the other would be a good starting point. Send the SIP calls out to a couple of OpenSER/OpenSIPS/Kamailio servers talking to several (like 4+) Asterisk servers. This way you can take individual servers out of production without disrupting everything at once. My 300 concurrent call project was taking SIP calls from a Tekalec 7000 talking to 4 hosts. Each host ran OpenSER on port 5060 and Asterisk on port 5061. The client loved the flexibility. -- Thanks in advance, - Steve Edwards sedwa...@sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [asterisk-users] DS3 capacity calls using asterisk
No usable DS3 cards for Asterisk. There is a standing consensus, as far as I've been able to tell (and I could be wrong), that this would be rather difficult - if not impossible - to do given the liberal timing tolerance of PCI buses and PC architecture once you're talking about that much synchronous payload and framing. There would be other problems, one of which is that it's not generally possible to handle that many calls concurrently with Asterisk on a single machine. Your best bet is to break a bunch of T1s out of an M13 mux, if you're determined to do this the TDM way. I'm not sure I see the point, personally; it's not because I think everyone should be using SIP origination (quite the contrary, it's still so broken in so many ways industrially), I just think that by the time it gets to Asterisk it can stand to be SIP. Get an ISDN-VoIP gateway that can take a DS3 and spit SIP out the back side and you're golden.
