3-WAY CALL CONFERENCING

The 420 allows you to bridge a call between any two lines to establish a 3-way conference call.

Place the first call on HOLD.
3 .
Initiate the second call.

NOTE:
In some instances where the two parties joined by the 420 are a long distance away from their telephone
company's central office, these two far end parties might not hear each other very well. If this occurs
frequently, it is recommended that the telephone company's 3-way calling service be used.*
Call Waiting Caller ID records will not be displayed or logged during a 3-Way Conference Call.
*Subscription to 3-way calling service is required.

TONE/PULSE MIXED DIALING
