You don't need to spend anything approaching $40,000 to use a Cisco router for four PRIs.
In your evaluation, consider also that the router is more reliable, has a worldwide service organization behind it, and let's a single PBX handle many more calls when it's relieved of transcoding (put voicemail on a separate cluster and one server will handle over 10,000 SIP calls). Many people look at initial purchase price instead of TCO. As you know, it's very expensive to lose 46 calls when a PC fails. We prefer not to put more than one T1 in a PC with a card and if we use two we use separate cards for each T1. Once you architect that way, the router approach costs about the same at four or more PRIs as I recall the numbers.

My plan is to eat up 4 PRIs in one office, send to my other office and convert back to PRI for my legacy switch. Voice quality is critical, would I be better off going with a Cisco AS5350 using hardware DSPs for the g.729 codec or is the Digium g.729 codec just as good with enough CPU to throw at it. The lack of dedicated DSP concerns me Option 1 PSTN PRI -> AS5350 -> (2 x T1) IP(SIP,g.729) -> AS5350 -> PRI -> PBX I would have 1 Asterisk server handling SIP, Conference, IVR, Voice Mail. I would purchase a bunch of g.729 codec licenses Option 2 PSTN PRI -> Asterisk -> (2x T1) IP (IAX2, g.729) -> Asterisk -> PRI -> PBX The first Asterisk would handle SIP, Conference, IVR, Voice Mail If the voice quality of the software g.729 codec is as good as the Cisco hardware codec I would *much* rather give my money to Digium, buy their hardware and licenses. If the quality isn't as good I may be forced to spend $40k on AS5350s I'm thinking 2.8 Ghz P-IV HT with 2 GB RAM for each Asterisk server. -Matt _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
