10.12.5.5 Call Hold Parameters
The call hold parameters are described in the table below.
Table 10-44: Call Hold Parameters
Parameter Description
Web/EMS: Enable Hold
[EnableHold]
Allows users (connected to the device) to place a call on hold.
[0] Disable = Disables the Hold service
[1] Enable = Enables the Hold service (default)
If the Hold service is enabled, a user can place the call on hold (or
remove from hold) using the Hook Flash button. On receiving a Hold
request, the remote party is placed on hold and hears the hold tone.
Notes:
To use this service, the devices at both ends must support this option.
This parameter can also be configured per IP Profile, using the
IPProfile parameter (see ''Configuring IP Profiles'' on page 122).
Web/EMS: Hold Format
[HoldFormat]
Determines the format of the SDP in the Re-INVITE hold request.
[0] 0.0.0.0 = The SDP "c=" field contains the IP address "0.0.0.0" and
the "a=inactive" attribute (default).
[1] Send Only = The SDP "c=" field contains the device's IP address
and the "a=sendonly" attribute.
Note: The device does not send any RTP packets when it is in hold state
(for both hold formats).
Web/EMS:Held Timeout
[HeldTimeout]
Determines the time interval that the device allows for a call to remain on
hold. If a Resume (un-hold Re-INVITE) message is received before the
timer expires, the call is renewed. If this timer expires, the call is released
(terminated).
[-1] = The call is placed on hold indefinitely until the initiator of the on
hold retrieves the call again (default).
[0 - 2400] = Time to wait (in seconds) after which the call is released.
Web: Call Hold Reminder
Ring Timeout
EMS: CHRR Timeout
[CHRRTimeout]
Defines the duration (in seconds) that the Call Hold Reminder Ring is
played. If a user hangs up while a call is still on hold or there is a call
waiting, then the FXS interface immediately rings the extension for the
duration specified by this parameter. If the user off-hooks the phone, the
call becomes active.
The valid range is 0 to 600. The default value is 30.
Notes:
This parameter is applicable only to FXS interfaces.
This Reminder Ring feature can be disabled using the
DisableReminderRing parameter.
