is there a less expensive alternative?

is there a less expensive alternative?

is there a less expensive alternative?

(OP)
I’m developing an application to record/play phone conversations.  I need 2 ports to record the sounds and one to play it back.  I do not need to receive calls or to dial out.  I’m simply recording phone conversations on a RJ-12 phone line.  What I do need, are API to start record and playback files on specific ports.

Since I will not be using the more powerful telephony capabilities of a regular telephony card (i.e. Dialogic, Brooktrout, etc), is there a less expensive alternative?  

Please send responses to:  Cpan@nineoneone.com   Thanks.

I doubt it (welcome correction if I am wrong).

Your application requires a multi port card, which rules out a consumer grade voice enabled modem card, plus the capaility to play back a sound file.

There are probably used cards you can buy that would be fairly inexpensive (comapred to new at least)

RE: is there a less expensive alternative?

Your post doesn't exactly make sense to me.  Why would you want to record on one and playback on the other (assuming that they are on the same line)?  A good, full-duplex voice modem should be able to handle what you want with a single port per line.

If you are looking for a multiport/multiline capability, I have used the COMTROL RocketModem with limited success.  You can get it in a 4 or 6 port model with drivers for Windows, Novell and Linux.  It is a half-duplex voice modem and should work fine as a telephone answering device.  I haven't tried it though, so I couldn't tell you for sure.

Of course it is only slightly more expensive to pick up a dialogic or brooktrout card on ebay, and the are infinitely superior for what you are attempting to do.

The difficulty with using a full duplex voice modem is finding a software tool that will work with it.

In rereading the post "I do not need to receive calls or to dial out.  I’m simply recording phone conversations on a RJ-12 phone line." , it sounds more like an audio application than a telephony application, almost like Dictaphone monitoring.  If you patched the audio out to a decent sound card, you could use some kind of sound activation to start recording when the phone goes off hook.

I assumed from his post that he intended to write an application.  Voice modems have a WAV device associated with them, so it should not be that difficult to create an app that plays and records audio as WAV files.
