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.

dtmf-supp-service supp-

reminder-ring
[DisableReminderRing]
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.

dtmf-supp-service supp-

during-hold
[PlayDTMFduringHold]
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.

[EnableTransfer]
Enables the Call Transfer feature.
 [0] Disable

message with the Referred-To header to initiate a call
transfer. For analog interfaces: If the transfer service is
enabled, the user can activate Transfer using hook-flash
signaling. If this service is enabled, the remote party
performs the call transfer.
