Hello, I have found and read Steven Critchfields writeup on how to use ZapRas (Thanks Critch!), however I am a bit confused. His write up is here: http://copilotconsulting.com/mail-archives/asterisk.2003/msg01030.html Currently we have a full PRI (23B Channels, 1D) coming into our Asterisk Box using a TE110P. Voice calls work great, and I have it all configured up. Now, I would also like to be able to use this box to establish a 128k (possibly 256k multilink) PPP connection to an ISP who supports 128k (2B's) or 256k (4B's) connection. One thing I don't get understand is, is the Asterisk/Linux box the modem? I am confused when he states that he used a "Ascend Pipeline 75" as I don't really understand how that fits into the equation. Can't asterisk dial our end ISP, and then I can set up routing at the linux level to interface with ppp0 device for example? Any help would be greatly appreciated! Thanks so much, - Brent
