Can traditional PBX and IPPBX be connected?

The current external interfaces of traditional PBX are mainly E1/T1 digital trunks and FXO analog trunk interfaces.

The current IP-PBX is mainly a soft switching system based on the SIP protocol, which interfaces with various devices through the IP protocol.

The connection between traditional PBX and IP-PBX must be done through gateway equipment.

It can be connected with traditional PBX through digital trunk gateway and analog trunk gateway.

The principle of the gateway is to convert digital trunks and FXO analog trunks into IP-PBX compatible SIP protocols.

This is a connection at the telephone level, and the gateway device has very powerful network connection capabilities.

For example, if the PBX wants to connect with the telephone system, it can choose the telephone gateway, if it wants to connect with the audio equipment, it can choose the audio gateway, and even with the private network PDT cluster system, it can use the DeSite cluster gateway.

Allows walkie-talkies to communicate with telephones.

Therefore, the connection between traditional PBX and IP-PBX is very simple.
