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.
Advantages
A VOIP service is like your traditional phone service. But instead of providing you with a physical phone line, a VOIP service provides you with a VOIP account that you can use to make phone calls over the internet to regular telephones. In addition, almost all VOIP services are based on the same SIP standard so you have many choices and can easily switch among them.
A PBX system that supports IP phones allows Voicent software or IP phones to connect as if it is a traditional extension. The only difference is that the connection is through computer networking instead of physical phone lines. If you are currently using a major brand PBX system, it is likely it supports IP extensions.
A SIP trunk is like your traditional phone trunk that accommadates large call volumes. The SIP trunk servce can be provided from dedicated lines or virtual lines from your existing Internet connection.
