Call Hold Parameters
For digital interfaces: Enables interworking of the Hold/Retrieve
supplementary service from PRI to SIP.
For analog interfaces: Enables the Call Hold feature that allows users,
connected to the device, to place a call on hold (or remove from hold).
This is done using the phone's Hook Flash button. On receiving a hold
request, the remote party is placed on hold and hears the hold tone.

[0] Disable

[1] Enable (default)
Notes:

For digital interfaces: To support interworking of the Hold/Retrieve
supplementary service from SIP to ISDN (for QSIG and Euro ISDN),
set the parameter EnableHold2ISDN to 1.

For analog interfaces: To use this service, the devices at both ends
must support this option.

This parameter can also be configured in an IP Profile.
Determines the format of the SDP in the Re-INVITE hold request.

[0] 0.0.0.0 = (Default) The SDP "c=" field contains the IP address
"0.0.0.0" and the "a=inactive" attribute.

[1] Send Only = The SDP "c=" field contains the device's IP address
and the "a=sendonly" attribute.

[2] x.y.z.t = The SDP "c=" field contains the device's IP address and
the "a=inactive" attribute.
Notes:

The device does not send any RTP packets when it is in hold state.

For digital interfaces: This parameter is applicable only to QSIG and
Euro ISDN protocols.
Defines 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] = (Default) The call is placed on hold indefinitely until the initiator
of the on hold retrieves the call again.

[0 - 2400] = Time to wait (in seconds) after which the call is released.
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 is 30.
Notes:

This parameter is applicable only to FXS interfaces.

This Reminder Ring feature can be disabled using the
DisableReminderRing parameter.
Disables the reminder ring, which notifies the FXS user of a call on hold
