Hello,

So I have a Motorola SM56 USB Data Fax Modem (aka Apple USB Modem for some people) and according to information online this modem supports V.92, Caller ID, wake-on-ring and most importantly telephone answering (V.253).

At a place I happen to have an old telephone analog line that gets calls and unfortunately I can’t get rid of. Any ideias / links / software on how can I use the modem + a low end box / ARM SBC to “digitize” the phone line into a generic SIP / VOIP that I can then connect to using MicroSIP on another computer?

Thank you.

Update on this:

I just tried the modem under Windows with a few programs such as Phone Dialer Pro and the built in dialer.exe and while the modem can detect incoming phone calls and place calls I can’t pass the audio back to the operating system / phone software.

I did some research about the SM65 and it seems like it was designed to have an headset directly attached to it like on those PCI cards that also use it:

The built in COM port of the modems seems to be only usable to control the modem via AT commands and can’t be used to pass audio form and to the system.

    I’d still start by calling your provider and see what they think. They might jump at the chance to get rid of an old analog line.

    Tried that route, they offered us a free cellphone line for a month and the thing was working around 2-3 hours a day around the middle of the day. They simply gave up and told me that they didn’t have other options on that location.
