Overview of four- and five-digit lines

Four- and five-digit telephone lines, commonly referred to as five-digit numbers, are sold by the telecom operator as inbound or inbound/outbound services and are available only to registered companies with a tax code. Installation and commissioning of the five-digit line after purchasing a copper pair is performed by the network design center. The five-digit line is offered in two modes: inbound-only, which includes only incoming calls, and two-way, which includes both incoming and outgoing calls.

The inbound line has a five-digit prefix and the two-way line has an eight-digit prefix. The five-digit line is delivered as copper wire pairs with a minimum capacity of 30 channels. Each pair can support up to 60 simultaneous calls without occupying other lines. The five-digit line or SIP trunk uses VoIP technology, which requires internet access and a modem. This setup requires specialized equipment and knowledge. At the network design center, all necessary design, installation, and commissioning services for the five-digit line are provided.

How to set up a five-digit line

At the Network Design Center you will benefit from dedicated services for setting up the five-digit line. After you receive the copper pair from the telecom operator, simply contact the SIP trunk installation center. Free telephone and in-person consultation is the first step of our collaboration. Then, based on your needs, we proceed with the necessary actions to install the five-digit lines at your company. This service can also be implemented on older PBX systems if you wish, so the work can be done on an older system.

The five-digit system and E1 connections

The five-digit system known as E1 lines requires an E1 PBX system. E1 PBX systems have a dedicated A1 port and can connect the trunk to internal numbers. The best approach for installing and setting up the five-digit line is to use VoIP via an internal E1-based PBX. At the network design center, all necessary consultations are provided. All you need to do is purchase the five-digit line from the telecom operator and visit the network design center to begin the work.

Setting up the five-digit Tel30

Individuals seeking to set up the five-digit Tel30 line can obtain Tel 30 through the telecom operator or providers of this line. Tel 30 offers all the features of the five-digit line and differs in that it is offered to individuals. If you want to access two-way features you can order a two-way line. When placing a call, three zeros are appended to the end of your number. After purchasing Tel 30, contact network professionals at the network design center to begin. We will be with you anytime, anywhere.
