Vialer

With the Vialer app you can use your smartphone for calling customers with your business phone number. You can also find the dialed and received calls quickly and easily in the recents call list. Moreover, you can view and modify the dial plan, statistics, and accessibility at any time you want.

Calling over 4G and WiFi
With the Vialer app you can call over 4G or WiFi. All you need is a VoIP account that is connected to your user account. With the VoIP account you can immediately start making VoIP calls.

If you do not have a 4G connection, the Vialer app uses the two-step conversation: it calls your mobile number first and then connects you to the contact you chose, showing him your business phone number.
