When you get beyond a dozen T1's or so what have you done? We've configured "t1 servers" with quad T1 cards which hand off calls to "application servers" via IAX and this is working pretty good, but, where do we go from here? Talk about Digium's DS3 card appears to have evaporated. What about a Tekelec or a Max TNT? What have you used to get in the neighborhood of 1,000 simultaneous calls into your Asterisk applications? How much did your solution cost and what problems did you experience? Did you drag a DS3 to your location or did you co-locate at the CO? Inquiring minds want to know :) Thanks in advance, ------------------------------------------------------------------------ Steve Edwards sedwards@sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000

These solutions work very well, and they offload all of the really heavy lifting to application-specific equipment which already has the appropriate hooks for highly-available networks. -A.
We are happy with our Max TNT as a gateway but we are only using a single PRI. We have been running this for about a year. It should be a reliable workhorse and scale well to a DS3. The big brother Lucent APX is there for more density. I think it has OC3 and higher cards. Our tnt handles SIP, g.729 compression and has echo cancelation built in. That takes some of the load off of our asterisk server. Have you checked with Sangoma lately? They have some great products. They were planning a DS3 card at one time. But if the demand is not there, I don't think we will see anyone make such a card.

Use multiple servers. What kind of calls are you handling that you can have more than 3 quad T1 cards in a single server and have your Asterisk-based application be functional? And what kind of server hardware are you using?

Sangoma has a DS3 card but iirc that one isn't channelized and rumours are they may release a channelized one.> What about a Tekelec or a Max TNT?MaxTNT and the APX series work very well. Onboard DSPs, echo can, g.729 transcoding, the works. And carrier class. There's also the Cisco AS5xxx stuff. You can pick up DS3 loaded MaxTNT boxes on eBay for a pretty reasonable price. Make sure it comes with a license for the OS. I've got no experience with Tekelec.> What have you used to get in the neighborhood of 1,000 simultaneous calls > into your Asterisk applications?That's more than a DS3 (28x DS1 or 672x DS0) but doing the math for a DS3 you only need 7 Asterisk servers with a 4 port T1 card in each. That's assuming you would take a DS3 in the MaxTNT/APX and send it as DS1 out to all the T1 ports on the Asterisk servers. Probably cheaper to just use SIP between the MaxTNT/APX and the Asterisk servers.> How much did your solution cost and what problems did you experience?Can't comment on the exact cost but if you go beyond a few dozen of those boxes (new) the numbers become quite enticing.> Did you drag a DS3 to your location or did you co-locate at the CO?Over here dragging it in usually means putting fiber into the ground. That can be pretty cost/time/effort prohibitive unless there's an ADM a small distance away. Co-lo the stuff. There's no need to become a datacenter operator. There are companies out there who have mastered that pretty well. Opting for a neutral co-lo will also allow you easier access to different carriers. Regards, Patrick
