What Is a PBX Phone SystemIf youíve been searching for the best business phone system for your company, chances are youíve been inundated with a lot of information. Today, you have more telecom choices than ever before. One of your options is a PBX phone system. So, what is PBX phone system, and is it the right choice for you?
What is PBX?
PBX stands for Private Branch Exchange. Think of it as an internal telephone network of a business or other entity. PBX phone system users can communicate with one another over the phone via internal lines, and make and receive external calls as well. A PBX phone system usually delivers business telephony features such as call forwarding, call transfer, call queue, auto-attendant, voicemail, etc.
PBX systems operate by using either VoIP (Voice Over Internet Protocol) or via analog or digital phone lines. With a PBX phone system, the physical phone line coming into your business can be split into multiple lines, allowing you to support more telephones. Better yet, calls between users are free.
Types of PBX Phone System
If you believe a private branch exchange phone system is your best choice, you still have some decisions to make. Check out each type of PBX telephone service that is available for your company.
Analog PBX Phone System
This is the traditional, intra-office telephone system, and has been around for decades. It is connected via Plain Old Telephone Service (POTS) lines to the PSTN (public switched telephone network). Phone calls, even fax transmissions are handled by the PBX using physical phone lines. The analog PBX phone system allows calls to be made and transferred within the location. They also handle the incoming and outgoing calls using outside lines.
Keep in mind that analog systems came before the Internet, and use traditional copper phone lines. This means they cannot use many of the modern-day features you might see in more advanced telephone systems such as multimedia services, converting voicemail to email, or remote working capabilities. Also, if your business grows, you may need to add new jacks and telephone wires to support additional employees. On the plus side, because traditional PBX systems are self-contained, connectivity is not impacted if the Internet were to go down.
VoIP PBX System
VoIP or IP PBX represents a newer version of private branch exchange. It has the same functions as a traditional PBX, but also provides many additional features. In addition to that, it may be a more cost-effective option. Rather than using traditional phone lines, IP PBX uses the Internet protocol. Voice is converted into data that is transmitted over the Internet, then it is converted back to voice for the receiver.
