Phone System Terminologies

PABX Phone Systems


PBX is short for Private Branch Exchange, which is a company’s private telephone network. Users of the PBX phone system share a number of outside lines for making and receiving external phone calls.

PABX is the most widely used phone system.

When you want to upgrade your old phone system to a new system there are a number of Internet Protocol (IP) based solutions that are available to small business.

VOIP Phone Systems


Voice over IP

You need an IP-based private branch exchange – a VoIP friendly version of the PBX phone systems that many offices use to route your calls to the appropriate phones on your network.

SIP / IP Phone Systems


SIP Phones are also called VoIP Phones or Softphones.

These are telephones that use VoIP technologies for making calls over both an IP Network or the traditional PSTN networks.

The differences between VOIP and SIP are discussed in details in this article.
