Stance on Compatibility


Our goal is to make every telephone, regardless of manufacturer, accessible. We work with several vendors to help them meet usability and accessibility requirements.

Any manufacturer not on this list but wishes to be, please contact us to discuss how we might work together.

Cisco Compatibility


Our application is based on the Microsoft Telephony API (TAPI). Cisco has chosen to support this API in depth. For this reason, accessaphone works very well with Cisco.
