Panasonic System Add-Ons & Expansion Cards

Designed to work alongside your existing telephone system, our Panasonic expansion cards and add-ons can simply slot in and add extra space where it's needed.

Here at PMC, we work closely with Panasonic to bring you authentic, branded expansion cards, all with the durability and assurance that you would come to expect from Panasonic.

Expansion cards are designed to allow you to build on your existing telephone system with ease, and they can make perfect sense to any business that is looking to grow and expand without purchasing a brand new telephone system.
