User's Manual 67. Configuration Parameters Reference
Version 6.8 971 Mediant 500L MSBR
Parameter Description
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.
Notes:
The parameter is applicable only to digital PSTN interfaces.
To enable the feature, the 'Play Busy Tone to Tel'
(PlayBusyTone2ISDN) parameter must be enabled (set to 1 or 2).
Web: Play Ringback Tone to
Tel
EMS: Play Ring Back Tone
To Tel
CLI: play-rbt2tel
[PlayRBTone2Tel]
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 c
ause 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):
Analog Interfaces: Plays a ringback tone to the Tel side only if
a 180/183 response without SDP is received. If 180/183 with
SDP message is received, the device cuts through the voice
channel and doesn't play the ringback tone.
Digital Interfaces: Plays according to 'Early Media'. If a SIP 180
response is received and the voice channel is already open
