    I've been running the ncidd with a Trendnet USB modem on an alway-on Ubuntu desktop for a bit more than a year. We're running a home business, so our land line is advertised on a couple of web sites and apparently fairly popular with telemarketers and scammers. (Recently the log showed 4 real calls in the last 20.) Now the phone rings once, ncidd catches it, makes an announcement and hangs up. We'll get up to answer it on the second ring. The android app lets me see who is calling before I get up from the couch, and I can look the number up and block it from any room in the house. I import additional blacklist numbers with the FCC2ncid tool. I whitelist my friends' cell phones so that their name shows up in the android app.

    Using on a Pi Zero with a phone Modem and Wifi, sat next to my internet Modem and powered by it's USB. The NCID is great, I can block any number and can also look-up any numbers to see if they are Cold call etc, an Europe one as in France, many more features, can't praise it enough.

    Very cool to be able to block annoying callers. The volunteer support here is superior to most paid applications. The only significant difficulty comes from the fact modems are all over the place with compatibility.

    Running this server on a Raspberry Pi. It's great. Love the blacklist feature. Excellent support too. Roule le serveur sur un Raspberry Pi. C'est génial. Adore la liste d'exclusion. Le support est en plus excellent. Keep up your great job John and thank you.
