iQall

iQall allows the user to make free calls from the Android smartphone via Epygi IP PBX. After installing iQall on the Android smartphone and configuring it with Epygi IP PBX, dial or select the number you want to call and press the “Call” button. iQall will send via the Internet a request to the Epygi IP PBX to connect your Android smartphone to the dialed number. The Epygi IP PBX will call you back via the mobile carrier and then connect you to the dialed number.
It doesn’t matter where you are, you can call to co-workers in the office by just dialing their extension number - the same as if you were in the office and calling from your desk phone. Your mobile number and the number you are calling should comply with the dialing plan for the Epygi IP PBX.
If you installed the Mobile Toggling license on the Epygi IP PBX, you can toggle the active call between your desk phone and the Android smartphone without dropping the call, unnoticeably to the other person on the call.
Since the Epygi IP PBX will place an initial call to your Android smartphone before connecting to the called number, the call to your Android smartphone will be free if you have a mobile service plan with free inbound calls. Also, since the connection to the called number is established by the Epygi IP PBX, you don’t need to pay for that connection on your Android smartphone, even for international calls.
If your Android smartphone is not tied with a specific carrier, you will save even more on roaming charges when traveling. Just install a SIM card from the local carrier and make calls using iQall. The Epygi IP PBX from your office will call you back via the ITSP (Internet Telephony Service Provider) or any other carrier configured in your Epygi IP PBX, and will connect the call. Your SIM card will not be charged at all.
The Epygi IP PBX can be configured with multiple carriers (cellular, local, long distance or VoIP) for placing external calls and the cheapest carrier will be used for connecting the calls.
