Parameter
Mediant 1000 Gateway & E-SBC | User's Manual
Description
■ [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: The parameter is applicable only to digital
interfaces.
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:
■ The parameter is applicable only to digital
interfaces.
■ To enable the feature, the 'Play Busy Tone to Tel'
(PlayBusyTone2ISDN) parameter must be enabled
(set to 1 or 2).
