What is VoIP?

VoIP (Voice over Internet Protocol) is a phone service that allows you to make and receive voice calls over your high-speed internet connection. With these services, you can make phone calls using your regular phone, an app on mobile devices, or a softphone on a computer, allowing you to call anyone with a telephone number, including local, long-distance, mobile, and international numbers.

02

How does one place or receive a VoIP phone call?

You use a VoIP phone the same way as a regular landline phone, picking up the phone to answer and dialing a number to place a call. There are also mobile apps for ease of use on mobile devices and softphones, with headsets with microphones for computer-based service.

03

Can I call any phone or just VoIP phones?

Most VoIP phones allow you to call anyone with a telephone number, including local, long-distance, mobile, or international. However, some providers may limit you to “User to User,” meaning you can only call those with the same service provider. VoIP phones also allow you to talk to multiple users simultaneously with a “Conference Call” or “Three Way Calling” feature.

04

How is the voice clarity?

VoIP calls have a voice quality at or above the quality of landline calls. Here at Callifi, we offer several different brands and models of VoIP phones for you to choose from to give you the most optimal user experience with your VoIP phone. Whether you are looking for a VoIP phone that is great for conference calls or a VoIP phone with great reliable speaker quality. Callifi is here for you and your business.

05

How secure are VoIP calls?

Here at Callifi the services we provide are SOC2 and HIPPA compliant. VoIP calls are quite secure and have endured decades of penetration testing, with that being said calls are only as secure as both parties systems are. So, double checking with the receiving party is recommended.
