Digital phone systems are often also referred to as Private Branch Exchange phone systems (PBX). These phone systems use digital signals that convert into sound for communication purposes. Digital PBX business phone systems are commonly used in the Vancouver, WA and Portland, OR areas, and can accommodate the various communication needs of small and medium sized businesses.

For businesses with dated technological infrastructures due to old wiring, unsecured phone lines, or unreliable internet connections, digital PBX phone systems are a popular choice. The control center for a digital telephone system resides at the location the phones are being used. This offers easy user control over the operation of the system and allows for the easy addition of phone sets, telephone lines, and other features. These digital PBX systems consistently provide better voice quality.

Furthermore, many digital PBX systems also have the ability to support VoIP phone lines and these phone systems are commonly referred to as Hybrid IP PBX Systems. Businesses with dated internal wiring are typically able to support a few VoIP phone lines, making Hybrid IP PBX phone systems highly desirable. There are many benefits to having a Hybrid IP PBX System including:

1. 1- The ability to connect remote offices or employees to the system
2. 2- It allows IP phones to connect to the center of the system for easy admin
3. 3- SIP trunking is supported by most Hybrid PBX systems
4. 4- Ease of transfer to a full VoIP phone system in the future
