Enterprise Trunking and How It Relates to SIP Trunking

Enterprise trunking refers to how enterprise Internet phone systems are connected to the public phone network. Trunks are bundles or carriers of lines, so a SIP trunk is a group of SIP lines together. These terms hearken back to the earliest ages of telephone service:

  • Lines: Telephone lines, which were in the past simply copper lines bringing telephone service from one point to another.
  • Trunks: A telephone trunk is a group of lines. These trunks would contain the lines that made up the public telephone network. Today, a trunk is also a way of thinking of the capacity for more than one line to be carried at once.
  • SIP (Session Initiation Protocol): SIP allows VoIP phones to communicate using Internet servers. It's a "language" for VoIP.

VoIP (Voice over Internet Protocol): Internet-based phone service.

  • SIP Trunking: Connects VoIP subscribers to the public phone system so they can make calls. SIP trunking is offered as a service by VoIP providers.
  • Enterprise Trunking: The link between an enterprise phone system and the public phone system, enabling the enterprise to communicate via phone with other phone users. Bundled with other services, enterprise trunking may be part of a UCaaS (Unified Communications as a Service) bundle offered to the enterprise by a VoIP vendor.

By using an enterprise trunking service, your organization can connect a PBX (private branch exchange) to the public phone service network and begin making phone calls through SIP trunking. You can add redundant trunks to provide the added infrastructure you can reroute traffic to. You can also connect together several locations and networks as if they were a single network under one roof.

This allows enterprises to share a single VoIP service and have shared connections and features. It all looks and behaves like one large network. With the higher call volumes and unique communications needs of larger enterprises, enterprise trunking provides added bandwidth and improved functionality.

The Difference Between Enterprise Trunking and SIP Trunking

Enterprise trunking, being the connection larger enterprises have to the public phone network, must be able to connect a large number of lines, multiple locations, and internal networks together into a single internal network. A single UCaaS system keeps everyone closes in communication across various channels and enables a unified link to the outside world of communications.

SIP trunking, by itself, can denote a connection to the public phone system without these enterprise-grade features. It could be, for instance, a part of a smaller organization's communications strategy.

What Are Some Applications of Enterprise Trunking?

Large enterprises need to stay connected and appear to operate as a unified, single organization even if they are very large and have multiple departments and segments. They also have to have enough capacity to successfully manage a large volume of communications simultaneously.

Enterprise trunking is perfect for connecting many different locations together, such as multiple headquarters. It's also a way to create a high-capacity call or contact center to handle a significant volume of corporate communications. Wherever team members are, they need to be meaningfully linked together — calls can go through a single phone queue, software applications can be shared, and a single phone network can function across different geographical locations.

Enterprise Trunking Services

Through SIP trunking or enterprise trunking, companies can connect their own internal phone networks together and also link to the outside public phone system. Trunks, or bundles of phone lines, allow for the free flow of communications across networks and the Internet. With the right capacity, enterprises can stay connected and create a healthy level of redundant communications infrastructure in case it's needed. Enterprise trunking is perfect for creating a contact center and managing corporate communications at large organizations.

With the right contact center or enterprise trunking service technology from enterprise SIP trunk providers, your organization can provide customer service, communicate among employees, hold conference calls, and collaborate in other ways. Through collaboration, you can improve your organization's productivity and find new ways to reach customers. Omnichannel communications are a feature made possible through enterprise trunking and with the right technology.
