A VoIP gateway is utilized to develop a bridge between the worlds of legacy telephone systems and the VoIP. Gateways are generally used to connect tradition phone systems (PBXs or ACDs) with VoIP resources, or to link modern VoIP phone systems with tradition phone lines.

Adding VoIP to a legacy PBX system is a terrific way to include functions and lower costs. The gateway links to the tradition system through either analog or digital trunk ports. The PBX sees the entrance as either the phone company or as another networked PBX. Calls from the PBX to the outdoors world are transformed into VoIP calls and sent out over the Internet to a VoIP company or other VoIP peers. Calls originating from VoIP sources are converted into the suitable legacy protocol and delivered to the PBX.

Using an entrance to connect a VoIP phone system to standard phone lines makes good sense in circumstances where SIP trunks are not available or where your application requires the dependability of the PSTN. It likewise makes it easy to construct redundant systems. The entrance normally communicates with a main IP PBX. In case of a failure on the primary, the entrance can interact with a backup system.

Other uses for VoIP gateways consist of staged migrations, where the entrance serves as a bridge in between the PSTN, a legacy PBX and a brand-new IP PBX. In this case, the PSTN trunks are connected to one user interface on the entrance. Another interface connects to the trunk port on the tradition PBX. The brand-new IP PBX is integrated over a VoIP procedure (generally SIP). The entrance directs some inbound calls to the tradition PBX and others to the IP PBX. It also passes calls between the two PBXs. This permits some department or other subdivisions of the business to stay on the legacy system while others transfer to the IP system.

Key Facts & Features

Gateways come in several formats. Analog entrances convert in between VoIP protocols and conventional analog phone lines and/or phones. Digital entrances transform between VoIP and various sort of digital phone services: T1, E1, PRI and/or BRI, depending on the entrance.

Gateways can usually link to several VoIP endpoints (gadgets or services), which permits PSTN resources to be shared in between numerous IP communications systems.

The routing functions developed into an entrance enable it to smartly adapt calls from one medium to another. For example, they can include or get rid of digits in the dial string when passing a call. They can also recognize different patterns and path them across various user interfaces.

Gateways can be utilized to transform VoIP calls from one code to another, a process referred to as transcoding. This can be useful when bridging several VoIP solutions together. VoIP calls online do need a strong Internet connection. Run a VoIP network test as an easy diagnostic tool to recognize the jitter, bandwidth, and latency on the Internet connection.

Key Benefits

Gateways can extend the life of tradition equipment by "VoIP allowing" it. This can include changing conventional trunk lines with SIP trunks or routing some subset of traffic over VoIP to a remote PBX or gateway - a process referred to as toll bypass.

Gateways enable flexibility. Instead of moving from a traditional PBX to an IP PBX in one step, a business can stage the migration using the gateway as a bridge between the two systems.
