I don't want to start the "How many calls can Asterisk handle?" discussion or "How many angels can stand on the point of a pin?" discussion either. But can anyone contribute some practical knowledge of systems that take in channel bank T1s or DS3s from "far away", and process the calls? I am looking for real world, been there, done that, or "check the 'Belchfire Systems GigaFiber 65536' system". Not to start the discussion, but "Is there a board that will take a DS3 (672 channels) and a system that will ha...

We have 3 sites located across the US. Each has its own Asterisk PBX with a stand-alone installation. The sites are connected via VPN, fully messed, with fractional DS3s to the same service provider. We'd like to set it up so that if the PBX at site A fails, it fails over to B or C, if the PBX at B fails it fails over to A or C, and so on. I know Cisco CallManager supports this using CallManager groups. Does Asterisk support it as well? Most of the th...

I have a customer installation with an Adtran DS3 mux. The DS1's go into my Asterisk servers that run IVR/Call recorders. The DS3 provider is Qwest, and they tell me that they routinely drop the DS3 service to redundant back-up's and that this is a common practice that happens thousands of times to DS3 lines daily across the US without any service interruptions. They say that the

Dear Asterisk Gurus: Our county is finally ready to begin implementing IP telephony. We intend to use a Cisco router as our PSTN gateway and Asterisk as our soft switch. The plan is to use SIP between the Cisco router and Asterisk. We will have a single PRI T1 connected to the Cisco router for PSTN access. My question is this: Are Cisco routers able to pass caller ID information (from PRI

...thorized SC Telcom employee like Steve and then sent to us. Please take care of this ASAP as we need to get the ball rolling on ordering interoffice transport circuits. Not only do we need these for Indy, Coffeyville, and our ATM DS3 from ASI, but we also need them for Augusta and Andover to order DS3s back to Broadway for the collocation equipment moves.

I'm looking to build a robust inbound DID access layer for an application I am working on. This might start off simply as 8 DID T1/ISDN lines and eventually grow to a few dozen T1 lines worth of access or higher. (In a prior life, I had 14 DS3s of inbound toll free terminating on Dialogic card based IVR platforms ... then one day the Asterisk/VoIP bug bit me but that's another story) So with my existing biases, I'm tempted to do one of two things: a) buy used Cisco Voice AS5300s (4 X T1 to SIP gateway for $3,200 and 2U of rack s...

I'm trying to set up an Asterisk system for a small office, and one thing I haven't figured out yet is how to best provide reliability. One way to go seems to be a T1 for all my incoming phone lines. What if that T1 goes down? Can I use mutiple POTS lines in conjuction with a T1, all connecting to my Asterisk server? What if my Asterisk server fails? Should I use two Asterisk servers,

Hello all, We are looking for some hardware requirements/recommendations to be able to handle a full DS3's worth of TDM -> VoIP traffic. The DS3 would bring 24 calls per T1 x 28 T1s = 672 simultaneous calls. We would then need to convert those calls into G729 SIP VoIP calls to send to our asterisk box over ethernet. Since everything is going in/out of asterisk is 729, and no features

i am looking at iax to see if it is applicable to my needs. i would appreciate any corrections of what i think i have understood but probably have not. iax uses udp and traverses nats. neither of these seems useful to me. i loathe nats, and udp is not well-behaved in the sense of congestion avoidance. trunking will save some bytes in flight iff one has four or more streams moving between two

Hi, Inspired by a recent rant about one particular provider, I am getting very curious about something I've never mastered. I'd like someone to explain this here or at least post a link or two that can educate me and probably countless others who have no knowledge in this area. I'm sure there are several of you reading this that know all about the subject. What are the various

Any know what Digium hasn't released the DS3 card? It was supposed to be out a while ago. -Matt
