Inter-Tel Telephone System Cards

Covering systems including the Premier / IMX / GMX and GLX through Axxess and CS5000 series, here you will find links to each specific system category below. Please note that due to the acquisition of Inter-Tel by Mitel, you may find equipment cross-branded here. If you're concerned about compatibility, please contact us for more information.

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.

While every effort has been made to correctly categorize this equipment for easy navigation, you may encounter some items that may not be compatible with your specific application, software release or other specific situation. Please feel free to contact us with any questions you may have about your exact needs and we will point you in the right direction even if we don’t have what you need.

The Inter-Tel 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 Inter-Tel 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.
