Upgrading From ACIDMU

Ascendis Caller ID Multiuser 3 is an easy upgrade from ACIDMU versions 1 and 2. We recommend the upgrade to all ACIDMU users because of performance and usability improvements.

Users of versions of ACIDMU before 3 can use version 3 in trial mode free for 30 days. ACIDMU users who purchased their license within the year preceeding a new release can use it free. Other users can purchase a new license at 50% off. Please contact support for your discount.
