Parameter Description
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.
Web: Play Ringback Tone to
Tel
EMS: Play Ring Back Tone To
Tel
[PlayRBTone2Tel]
Determines the playing method of the ringback tone to the Trunk
(for digital interfaces) side.This 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 to 1, it plays a ringback tone and sends an ISDN Alert
with PI = 8 (unless the ProgressIndicator2ISDN_x
parameter is configured differently).
2) If the LocalISDNRBSource parameter is set to 0, the
device doesn't play a ringback tone and an Alert message
without PI is sent to the ISDN. In this case, the PBX /
PSTN plays the ringback tone to the originating terminal.
Note that the receipt of a 183 response does not cause
the device configured for ISDN to play a ringback tone; the
device issues a Progress message (unless
SIP183Behaviour is set to 1). If the SIP183Behaviour
parameter is set to 1, the 183 response is handled the
same way as a 180 Ringing response.
 [2] Prefer IP = (Default):

Plays according to 'Early Media'. If a SIP 180 response is
received and the voice channel is already open (due to a
previous 183 early media response or due to an SDP in
the current 180 response), the device configured for ISDN
/ CAS doesn't play the ringback tone; PI = 8 is sent in an
ISDN Alert message (unless the
ProgressIndicator2ISDN_x parameter is configured
differently). If a 180 response is received, but the 'early
media' voice channel is not opened, the device configured
for CAS plays a ringback tone to the PSTN. The device
configured for ISDN operates according to the
LocalISDNRBSource parameter:
1) If LocalISDNRBSource is set to 1, the device plays a
ringback tone and sends an ISDN Alert with PI = 8 to the
