I am already using Meridian Mail. Can I just install CallPilot?
It can be installed on any Meridian PBX operating on X11 Release 23C. Customers have the option to bring the system on-line and move all their users at once, or have it run side by side with Meridian Mail to gradually move users to the new system. It is designed to integrate seamlessly into an existing Meridian Mail Network by offering both standards-based and proprietary networking options while keeping the same touch-tone user interface.
