What are PABX and VoIP Telephony Systems?
PABX (Private Automatic Branch Exchange) is a business telephone system that manages calls through a centralized network. It supports internal extensions, call routing, and external lines so teams can communicate efficiently within the office and with customers.
VoIP (Voice over Internet Protocol) delivers voice communication over the internet instead of traditional phone lines. Combined with PABX, it gives businesses greater flexibility, clearer call quality options, and typically lower communication costs.
Key benefits of PABX & VoIP for your business:
- Efficient call management and routing across teams and locations
- Lower communication costs compared with traditional telephony
- Support for remote and hybrid working
- Easy scalability as your business grows
- Advanced features such as IVR, voicemail, and call recording
