User's Manual
Determines whether the device plays a comfort tone (Tone Type
#18) to the FXS/FXO endpoint after a SIP INVITE is sent and
before a SIP 18x response is received.

[0] Disable (default)

[1] Enable
Note: This parameter is applicable to FXS and FXO interfaces.
Defines the duration (in seconds) for which the offhook warning
tone is played to the user.
The valid range is -1 to 2,147,483,647. The default is 600.
Notes:

A negative value indicates that the tone is played infinitely.

This parameter is applicable only to analog interfaces.
Enables the device to play a busy or reorder tone to the PSTN
after a Tel-to-IP call is released.

[0] Don't Play = (Default) Immediately sends an ISDN
Disconnect message.

[1] Play when Disconnecting = Sends an ISDN Disconnect
message with PI = 8 and plays a busy or reorder tone to the
PSTN (depending on the release cause).

[2] Play before Disconnect = Delays the sending of an ISDN
Disconnect message for a user-defined time (configured by
the TimeForReorderTone parameter) and plays a busy or
reorder tone to the PSTN. This is applicable only if the call is
released from the IP [Busy Here (486) or Not Found (404)]
before it reaches the Connect state; otherwise, the Disconnect
message is sent immediately and no tones are played.
Note: This parameter is applicable only to digital PSTN
interfaces.
Determines the playing method of the ringback tone to the Tel (for
analog interfaces) or Trunk (for digital interfaces) side. For digital
interfaces: This parameter applies to all trunks that are not
configured by the PlayRBTone2Trunk parameter (which defines
ringback tone per Trunk).

[0] Don't Play =

Analog Interfaces: Ringback tone is not played.

Digital Interfaces: The device configured for ISDN / CAS
doesn't play a ringback tone. No PI is sent to the ISDN
unless the ProgressIndicator2ISDN_x parameter is
configured differently.

[1] Play on Local =

Analog Interfaces: Plays a ringback tone to the Tel side of
the call when a SIP 180/183 response is received.

Digital Interfaces: The device configured for CAS plays a
local ringback tone to the PSTN upon receipt of a SIP 180
Ringing response (with or without SDP). Note that the
receipt of a 183 response does not cause the device
configured for CAS to play a ringback tone (unless the
SIP183Behaviour parameter is set to 1). The device
configured for ISDN operates according to the
LocalISDNRBSource parameter:
1) If the device receives a 180 Ringing response (with or
without SDP) and the LocalISDNRBSource parameter is
