BRI Suspend and Resume

The device supports call suspend and resume services initiated by ISDN BRI phones connected to
the device. During an ongoing call, the BRI phone user can suspend the call by typically pressing
the phone's "P" button or a sequence of keys (depending on the phone), and then on-hooking the
handset. To resume the call, the phone user typically presses the same keys or button and then off-
hooks the phone. During the suspended state, the device plays a howler tone to the remote party.
This service is also supported when instead of pressing the call park button(s), the phone cable is
disconnected (suspending the call) and then reconnected again (resuming the call). If the phone
user does not resume the call within a user- defined interval (configured by the HeldTimeout
parameter), the device releases the call.
Only one call can be suspended per trunk. If another suspend request is received from a
BRI phone while there is already a suspended call (even if done by another BRI phone
connected to the same trunk), the device rejects this suspend request.

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.
