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?

Sangoma makes a DS3 card but it is not channelized for voice usage. We had a conversation with them at one point for a particular project and if I recall they do have a solution for running channelized voice over DS3. Give them a call or email, they are incredibly responsive and 'know their stuff'. Tim Nelson Systems/Network Support Rockbochs Inc.

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 sedwards at sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000

Cisco sells something called an AS5300 that supposedly can terminate a DS3 and convert it all to SIP. Otherwise, you need a channel bank like the Adtran MX2800 to break the DS3 into 28 T1s, which you can then terminate in your preferred manner, either into appliances or actual PC hardware with Digium cards.
