"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.
Note:

The device does not send any RTP packets when it is in hold state.

Digital interfaces: The 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 the parameter. If the user off-hooks the phone, the
call becomes active.
The valid range is 0 to 600. The default is 30.
Note:

The 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
or a waiting call when the phone is returned to on-hook position.

[0] = (Default) The reminder ring feature is active. In other words, if a
call is on hold or there is a call waiting and the phone is changed from
offhook to onhook, the phone rings (for a duration defined by the
CHRRTimeout parameter) to "remind" you of the call hold or call
waiting.

[1] = Disables the reminder ring. If a call is on hold or there is a call
waiting and the phone is changed from offhook to onhook, the call is
released (and the device sends a SIP BYE to the IP).
Note:

The parameter is applicable only to FXS interfaces.

The parameter is typically used for MLPP, allowing preemption to clear
held calls.
Determines whether the device sends DTMF signals (or DTMF SIP INFO
message) when a call is on hold.

[0] = (Default) Disable.

[1] = Enable - If the call is on hold, the device stops playing the Held
tone (if it is played) and sends DTMF:

To Tel side: plays DTMF digits according to the received SIP
INFO message(s). (The stopped held tone is not played again.)

To IP side: sends DTMF SIP INFO messages to an IP destination
if it detects DTMF digits from the Tel side.
