Parameter Description
[PlayBusyTone2ISDN]
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.
[Q850ReasonCode2PlayUserT
one]
Defines an ISDN Q.8931 release cause code(s), which if mapped
to the SIP release reason received from the IP side, causes the
device to play a user-defined tone from the installed PRT file to the
Tel side. For example, if the the received SIP release cause is 480
Temporarily Unavailable and you configure the parameter with
Q.931 release code 18 (No User Responding), the device plays the
user-defined tone to the Tel side.
The user-defined tone is configured when creating the PRT file,
using AudioCodes DConvert utility. The tone must be assigned to
the "acSpecialConditionTone" (Tone Type 21) option in DConvert.
The parameter can be configured with up to 10 release codes.
When configuring multiple codes, separate the codes by commas
(without spaces). For example:
Q850ReasonCode2PlayUserTone = 1,18,24
If the SIP release reason received from the IP side is mapped to
the Q.931 release code specified by the parameter, the device
plays the user-defined tone. Otherwise, if not specified and the
release code is 17 (User Busy), the device plays the busy tone and
for all other release codes, the device plays the reorder tone.
Note: To enable the feature, the 'Play Busy Tone to Tel'
(PlayBusyTone2ISDN) parameter must be enabled (set to 1 or 2).
Play Ringback Tone to Tel
[PlayRBTone2Tel]
Determines the playing method of the ringback tone to the Trunk
(for digital interfaces) side.The parameter applies to all trunks that
are not configured by the PlayRBTone2Trunk parameter (which
defines ringback tone per Trunk).
 [0] Don't Play =
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 =
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 set
