PABX integration-FXO

PABX integration-FXO Introduction

PABX has been around for nearly a hundred years, and today there are many manufacturing-type companies still using PABX. When customers find us looking for solutions, especially for manufacturing-type companies. These companies d still use the original PABX. Usually, They asked us a question, can we integrate the new VOIP phone system with the traditional PABX? The answer is certainly yes. Next, we will provide you with a docking solution for IP telephony and analog switches for this topic.

PABX integration-FXO Explanation

Next we introduce the gateways and devices that appear in the figure.

3CX System – This system will be deployed on the enterprise’s existing TCP ip network. It will serve as a new voice communication system for enterprises.

IP Phone – It will be used as a telephone extension in a new system. IP telephony is simple to deploy, it can be deployed in an enterprise’s existing TCP/IP network deployment, and only one network cable needs to be deployed on each card slot. There is also no need to deploy additional phone lines. An IP phone has two network ports, one network port is connected to the office network, and the other network port is connected to the office computer. This design allows companies to use the existing network of a network cable to enable simultaneous telephone communications and computer work.

PABX – Here we assume the voice communication system that the enterprise originally used. Any brand can be used, and the method of setting the connection method is similar.

Analog Phone – This is an old-fashioned telephone used with analog switches.

PABX FXO– This is the PABX’s internal telephone interface. This interface is used to connect to an analog telephone.

PABX FXO– This is the PABX’s external telephone interface. This interface is used to connect to the PSTN telephone line.

RJ11 Phone line: This is the standard copper core phone line

FXO IAD – It does the connection via TCP/IP and 3cx systems. Its interface will connect to the FXS of the PABX. The working principle of this scheme is that all extensions of the entire 3CX IP telephone system are called as an extension under the PABX.

FXS IAD – it is connected via TCP/IP and 3cx systems. Its interface will connect to the FXO of the PABX. The working principle of this scheme is that the entire PABX is called out as an extension under the 3CX IP Telephony system.

 

Dialing Rule-A

3CX connects two IAD and IP phones via TCP/IP. IP IAD consists of two voice gateways, one is FXO IAD; the other is FXS IAD. The FXS IAD is registered as an extension 701 under 3CX. The IP phone 101 can directly dial the 301 analog phone. 301 will display 4XX (depending on the number of the extension of the internal interface of PABX). Each call will occupy a telephone line inside the PABX. It will be released after the call ends.

 

 

Dialing Rule-B

The analog telephone 302 can dial the IP telephone 102 according to the prefix 9+102. When the analog extension 301 dials 102, the 102 caller ID will be 701 (depending on the number of the extension of the FXS of the PABX). Each call will occupy the FXO phone line of the PABX. After the call is over, the call will be released.
