The Verizon Business SIP Trunk program provides cited in these Application Notes are designed for small business clients. The program allows local and long distance calls through standard SIP Trunks, without the use of additional TDM or corporate gateways and the associated maintenance expenses. The Verizon Business SIP Trunk is one of the fastest SIP networks available, which allows for easy, secure and cost-effective communication between two or more SIP Service Providers.
The Verizon Business SIP Trunk program is similar to other Trunk services offered by Verizon. There are three components of this type of service, a SIP Gateway (server), SIP Server, and Client Access Gateway (commonly known as “Gateway Agent”). When you call into a SIP Trunk from any telephone, it is forwarded to a SIP Server, which then forwards the call over to a SIP Client Access Gateway. The Gateway Agent can be used to control security parameters, such as call encryption, and to manage the SIP Server settings.
SIP Gateways is similar to the normal IP PBX Gateways, with only one major difference: they have dedicated IP addresses. The SIP Server uses a generic TCP/IP address to talk to the SIP Gateway. This means that when you dial a number, the call will automatically go to the appropriate SIP Server. If the SIP Server receives an unrecognized SIP Gateway Address, it will not make any calls to the destination.
The basic function of the Verizon Business SIP Trunk is to forward all calls coming from SIP Trunks to the appropriate SIP Gateway, with the exception of calls made directly from an outside SIP Service Provider. These SIP calls are normally forwarded to the Gateway Agent, and only a specific set of SIP numbers are allowed to get through. SIP Trunks that cannot be forwarded usually go straight to a Verizon VoIP Back Office phone system.
SIP Trunks is used for Voice Over Internet Protocol (VoIP) telephony on the Internet. You are able to connect your phone to the internet to make international calls and make local calls from the same SIP Trunk, just like regular phones do, with additional capabilities such as caller ID and caller waiting.
There are three types of SIP Trunks that are supported by this program. The first is the Basic SIP Trunk, which supports both local and international calls. The second is the Enterprise SIP Trunk, which provide both local and international calls, but is more flexible and supports various advanced features including multiple extensions, gateway forwarding, and gateway automation.
The third SIP Trunk is the Wide Area Trunk, which provides SIP based services in a single, flexible environment. The Wide Area Trunk offers features similar to Wide Area Network (WAN) but is network-centric, meaning that it is not limited by physical hardware and software limits.
