    I was told that, this app will make calls without using your regular phone # but heck, my number flashes whenever I call....

    The best there is. I'd like an option for adding custom provider logos though. As two of the three I use aren't listed. Namely neophone (Hungary) and Ventengo (Germany) other than that, I'm very happy with this app. 5*

    Great SIP client. I do VOIP systems engineering and installations for a living, this is a great client that I use both personally on my home lab as well as professionally when I need to set up a SIP endpoint for testing on a client's network. Has pre-configured profiles for lots of SIP carriers, and is super easy to set up on your own system with the basic, advanced, and expert profiles for when you need to do some hardcore tweaks.
