Good for keeping track of your balance. That's all I really wanted it for. An easy way to check my balance without the hassle of logging into the website. It is excellent for that. The app is otherwise completely useless. I could not get it to make a call with my Callcentric account. It just says "call failed".
Cannot place outgoing calls, not a real VoIP app. Good for checking balance as others have stated, but thats about it. I still love callcentric's service however, and I use the CSipSimple app with their service and its been great!
Android Cupcake App (Android 1.5) This app is outdated and stale; it has absolutely no functionality. Download it only if you want to relive the nostalgia of the old, old, old UI of Cupcake!
These guys are a joke I would explain but honestly it's not even worth a minute of my time to write it. Should be out of business.
Total and complete GARBAGE! I switched to Vonnage for the same low price ($9.90 per month) and recomend you do too. 1. Callcentric does not offer phone support, vonnage does. 2. Callcentric does not offer a device, you need to contact grandstreem or who ever, buy a device for $200, pay $300 to configure and ship, monthly maintainance fees on top, vonnage this is all free. If you have callcentric I recommend you contact vonnage and have your number ported to them.
Unimpressed I'm on Android 4.4.4 on a 2013 Moto X. The app installed. It will place calls, but when connected I cannot hear the person I called. I know it connected because I get voice mails with the other person just saying hello. Please fix this app.
