I would suggest you avoid the AudioCodes units, AudioCodes blatantly ignores the GPL and refuses to release even their kernel source. On 4/10/07, Mike <[EMAIL PROTECTED]> wrote:
Thanks Alex, That was my original thought, to just buy a TDM400 from Digium and put in as many FXO as I wanted, but I liked having the ease of just buying something off the shelf, even if it meant paying a little more. But it looks like I won't have much of a choice.

Most ATAs come with FXS ports so that you can connect analogue phones to them, but in this case you're wanting to take PSTN lines from the outside, so FXO is desirable. Second, you'd have to make sure that the "ATA" supports the sort of application you're using it for; most are manufactured on the opposite premise. I am actually not sure offhand of any ATA firmware that I know that I imagine would work this way, although I'm confident it exists as consecutive back-to-back analogue<->VoIP adaptations in many scenarios can get quite complex and requires that flexibility. Basically, you're looking for a small IP PBX that uses SIP internally among its private nodes and takes PSTN trunks from the outside. That's what PBXs typically do. :-) If all else fails, you can always roll your own functionality of this nature by using FXO cards in Asterisk. There are various distributions that package it in a very lightweight and reusable manner specifically for this type of purpose, or you can roll your own if it's scalable enough. -- Alex -- Alex Balashov <[EMAIL PROTECTED]> _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
