I've placed an order for a USR5637, which USR is clear is a "controller" and not a softmodem (in contrast to their recommended replacement USR5639). I'll report back if it can be made to work with the Ooma. Closing the loop on this, while I only have a few days on it so far, I can report that the USR5637 does seem to work with the Ooma Telo over a multiday period with the default ncid.conf settings. In particular, its working long after the Conexant would have stopped notifying on ring. I have not...

Thanks Todd, since it doesn't work on current macOS I'm going to assume the driver has been removed. I may be able in investigate later on an older macOS VM to poke at the com.apple.driver.AppleSM56KUSBModemFamily driver bundle, but I suspect all that will show is that it is a softmodem. In particular the AppleSM56KUSBAudioEngine subtree strongly implies to me that they are doing the audio processing in software. I think we can assume that the wikipedia page needs to be clear that the USB modem doesn't...

Hi Todd, thanks for the update! Is it possible the Motorola SM56 is a softmodem? Press releases found on Google seem to suggest it might be. I had assumed a USB Apple modem might work as well as the wikipedia entry since it might have the same chipset, which seems to be true, But if that original entry was also tested on a Mac it seems possible Apple is bundling the softmodem drivers and that's what makes it work? I wonder if an examination of 'ioreg -l' on the Mac might give us a driver name and...

Hi Todd, Thanks for clarifying the Wiki. I was going to run the same experiment myself and order the modems when I return from a trip, but I'll wait to hear your results. I think the 5637 may make more sense, but I suspect I'll have to try both with the Ooma if they are shown to work in general. Since I no longer have the POTS line to test against knowing the Apple modem works for someone else will at least mean I am only testing one variable (the Ooma) and not just encountering an incompatible modem....

I've used NCID successfully with a AT&T POTS line with a Zoom USB modem (Conexant chipset) connected to a Linux PC (not a Pi). Over the last few months I've been trying to use the same modem with an Ooma Telo VOIP device with minimal success. The Telo works fine with my Uniden phone handset CID, so its definitely sending CID info. My core problem is that CID info is only received sometimes. Running in debug mode I get RING and CID info for a while, but eventually it stops appearing. Plugging the...
