Consultation Feature

The device's Consultation feature allows you to place a call on hold and then make a second call to another party.

After placing a call on hold (by pressing hook-flash), the holding party hears a dial tone and can initiate a new call, which is called a Consultation call.
While hearing a dial tone or when dialing to the new destination (before dialing is complete), the user can retrieve the held call by pressing hook-flash.
The held call can’t be retrieved while ringback tone is heard.
After the Consultation call is connected, the user can toggle between the held and active call by pressing the hook-flash key.

Consultation calls are applicable only to FXS interfaces.
