The Difference Between Analog PBX and IP PBX

Analogue PBX systems are the traditional old-fashioned telephony system and have been around for decades, and they work by connecting landlines. Using old copper landlines, analogue PBX systems like Panasonic PBX lack modern call control functionalities like multimedia services and lack integration with CRM.

On the other hand, VoIP PBX systems are the newer version of PBX systems using the VoIP (Voice Over IP) technology to make and receive a large number of calls at low costs.  

With an IP PBX system, you have access to all unified communication functionalities, video conferencing, and more. VoIP PBX beats the analogue in terms of features, flexibility, cost, and reliability in the long run. That’s why businesses today are ditching landlines and taking the shift towards VoIP.
