What is Local Voice?

For companies that have an existing PBX and need a cost-effective solution for voice and data, purchasing ISDN-PRI service (Integrated Services for Digital Network- Primary Rate Interface) could be the right decision.

ISDN-PRI is an advanced digital voice and data service. It divides a T1 digital signal into 24 voice channels, with 23 of those channels being used to place and receive phone calls, or carry data. The 24th channel cannot be used for placing or receiving calls, as it is used for providing voice features and also for providing signaling for the other 23 channels.

Benefits of Purchasing an ASDN-PRI

  • Customers can have up to 23 concurrent call paths per circuit.
  • ISDN-PRI supports an unlimited amount of DID’s, making it scalable for growing companies.
  • Each employee can have their own phone number.
  • The circuit is provisioned on a physical line, providing it with guaranteed bandwidth.
  • ISDN-PRI has been around forever, and is tried-and-true.

ISDN-PRI circuits are popular among many businesses because it’s nimble. Instead of purchasing separate circuits to meet their needs, it can allow a business to run those services over one physical line. This helps to simplify the solution to the customer, and also helps to lower the overall cost. The circuits are also built and configured as “Dynamic”, meaning that it will instantly allocate channels to specific uses when they are needed. For example, when a call is placed or received, the necessary channel(s) are pulled so the call can be completed, making them unavailable for data use. As soon as the call is completed, the channel(s) are released and can then be used for data.
