phones.IPTS Mobile lets the callers make VoIP calls through their standard
Mobile phones. The Android dialer works just like standard SIP Softphones i.e.
it gets registered on the SIP server and then let the authentic caller makes calls. The biggest advantage that this Android dialer provides is the huge base of potential customers who
can now make calls using their standard mobile phones. The mobile phones need to be connected
to the internet either through Wi‐Fi/3G.
