Frequently Asked Questions

What is VoIP?
VoIP stands for Voice over Internet Protocol. VoIP is a type of technology that enables users to make and receive phone calls using broadband Internet connection instead of a standard phone line. When using Simplefone’s solutions, a user can convert analog voice calls into data that’s transmitted over a high‐speed private IP network or the public Internet.
What’s the difference between broadband telephone, VoIP and cloud telephony?
All three concepts are similar in the type of technology. All phone calls are routed over an IP network and in all cases, the network that is used to route calls can be a public or a private network. Simplefone prides itself on security and therefore only routes calls over a private network in an effort to ensure the highest quality of service can be maintained.
What is the PSTN?
PSTN stands for Public Switched Telephone Network. PSTN is a traditional analog phone network that was established as part of the old Bell system.
What is SIP Trunking and how does it work?
SIP stands for Session Initiation Protocol, which is the way you achieve a voice over IP (VoIP) call. It’s an application layer protocol for setting up real-time sessions of audio and/or video between two endpoints in this case, phones. In other words, SIP is the technology that creates, modifies, and terminates sessions with one or more parties in an IP network, whether a two-way call or a multi-party conference call.

A SIP trunk is the virtual version of an analog phone line. Using SIP trunks, a SIP provider can connect one, two, or twenty channels to your PBX, allowing you to make local, long distance, and international calls over the Internet. If you have an on-premises PBX in your office, a SIP trunk provider can connect to you and allow you to make outbound calls on your existing system, without restrictions on the number of concurrent calls.
