Multi-Tech CallFinder Quick Start Getting Started
7
Prerequisite: Ordering the DID Lines
To operate the CallFinder system, you will need one or two DID
(Direct Inward Dial) lines in your office. You must order the DID
lines from your local telephone operating company (telco). A DID
line allows one phone line to be associated with multiple directory
numbers. However, only one call can occur on this line at any given
time.
DID lines are sold in groups. For example, a telco in New York City
might offer a DID line with a set of 10 directory numbers in the range
of 212-555-4100 through 212-555-4109.
When ordering your DID line, ask the telco representative for these
details about the DID service. These details will be important when
setting up your CF220 unit.
