EPABX is an abbreviation for Electronic Private Branch Exchange. It is applied for internal incoming and outgoing phone calls. In case, you possess 2 phone lines, then it can be split into 8 lines. The incoming and outgoing phone calls can be conducted from these 8 numbers, simultaneously with only 2 phone numbers or lines. Without EPABX, if a staff member needs to contact his/her colleague within the office, then they will make normal phone call, which will cost money.

Distributing external calls across multiple lines is unimportant, but if you have a couple of lines when subscribed lines are in dozens, then phone bills can be scary. In addition, manually distributing loads across many lines is stressful due to tasks enormity. All the EPABX systems are not designed equally. There are different types of brands that need unique configuration to challenge with.
