Avaya Telephone System Cards and Modules

Including all Avaya / Lucent / vintage AT&T systems going back to Spirit, Merlin and Legend through modern IP Ofice and Communications Manager, here you will find any product under this large brand umbrella.

Including any core function or expansion cards and modules, here you will find our current selection of office phone system cards to replace any defective parts or add new functions or features to your existing system.

The Avaya / Lucent / AT&T system equipment offered for sale here includes main processor cards which function as the brain of your phone system and options for adding analog or PRI CO lines, adding analog / single line extensions, adding proprietary digital extensions, adding voicemail and/or auto-attendant, or adding optional interfaces for paging, SMDR reporting, music on hold or other features.

Please note that most Avaya / Lucent / AT&T telephone systems have limits about what type of card / module can be added as well as total system capacities which may prevent you from expanding your system as you intend. If you're unsure about capacity, potential licensing issues or any other concern, please contact us and we will get back to you as quickly as possible with whatever help we can offer.
