[Asterisk-Users] Is it possible to use IAXY device to make 56K modem calls
ALL, is it possible to plug a standard analog 56K modem into my iaxy device and make a modem call out? 9600 baud call would be fine actually. I just want to make a call out with my iAXy device and eliminate my PSTN line. THanks, Jerry

On a clean cable modem with a channel bank and T1 card I could occasionally get 14.4 connections but it would quickly drop to unusable as soon as either a frame was dropped or the jitter increased. -- Steven Critchfield <critch@basesys.com>

You couldn't use anything other than the G.711 codec, and the modem would probably think it was on a terrible line, but it should be possible to estabish a carrier (in theory). You'd want to change settings in your modem to allow it to tolerate the circuit quality, and your applications at either end would need to account for loss of packets. Are you SURE this is the best way to do this? All a modem essentially does is extend a serial connection across a telephone line, so why not figure out a better way to carry the serial connection to the far end?
