How It Works
Instead of requiring separate physical telephone lines for every employee, DID technology allows multiple virtual numbers to operate over a smaller number of communication channels. Your PBX system intelligently routes incoming calls to the correct extension or destination automatically.
For example, a business may have dozens of direct numbers assigned to staff members while using only a few active call channels at a time. This provides flexibility, scalability, and significant cost savings.
