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.
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.
Though I will warn you that IP telephony, while generally reliable, is still not as reliable as POTS. If this is critical to life safety, I’d just not mess with it.
I’m not aware of any software to do that, but I’m sure it exists. If you want to buy a device, you can get an FXO gateway or hybrid ATA. Those will let you use a VoIP phone over a POTS line, I think.
Also, if you already have Internet access, perhaps you might get a femtocell to provide local cell service over that ADSL connection.
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.
