What is VOIP?

VOIP allows users to make telephone calls over the internet to other VOIP users free of charge and to landlines and cell phones for a minimal fee. Since calls are made over the internet, you no longer need a physical phone line. VOIP stands for Voice Over Internet Protocal.

 

What is SIP?

SIP is a standard for VOIP. With SIP, you use a SIP softphone to make phone calls from your computer. A SIP softphone is simply a piece of SIP client software with a telephone-like user interface. Each line started by Voicent software acts as a SIP softphone. Once you setup and configure Voicent for SIP, you can use any Voicent program as if you are using regular telephone lines.

 

SIP Termination

A VOIP service feature that allows you to call both local, long distance and international phones and cell phones directly from a SIP softphone (thus from Voicent).

 

DID Number

Stands for Direct Inward Dialing Number. The number looks exactly the same as a regular phone number and it allows anyone to call your SIP softphone from a landline or mobile phone.
