Version 7.2 1173 Mediant 500 MSBR
User's Manual 74. Configuration Parameters Reference
ISDN (unless the ProgressIndicator2ISDN_x parameter is
configured differently).

If LocalISDNRBSource is set to 0, the device doesn't play
a ringback tone. No PI is sent in the ISDN Alert message
(unless the ProgressIndicator2ISDN_x parameter is
configured differently). In this case, the PBX / PSTN plays
a ringback tone to the originating terminal. Note that the
receipt of a 183 response results in an ISDN Progress
message (unless SIP183Behaviour is set to 1). If
SIP183Behaviour is set to 1 (183 is handled the same way
as a 180 with SDP), the device sends an Alert message
with PI = 8 without playing a ringback tone.

[3] Play Local Until Remote Media Arrive = Plays tone
according to received media. The behaviour is similar to option
[2]. 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 plays
a local ringback tone if there are no prior received RTP
packets. The device stops playing the local ringback tone as
soon as it starts receiving RTP packets. At this stage, if the
device receives additional 18x responses, it does not resume
playing the local ringback tone. Note that for ISDN trunks, this
option is applicable only if LocalISDNRBSource is set to 1.
Note:

The parameter is applicable only to the Gateway application.

The x in the ini file parameter name denotes the trunk number,
where 0 is Trunk 1.

The parameter is applicable only to digital interfaces.
Play Ringback Tone to IP
configure voip > sip-definition
settings > play-rbt-2ip
[PlayRBTone2IP]
Global parameter that enables the device to play a ringback tone
to the IP side for IP-to-Tel calls. You can also configure this
feature per specific calls, using IP Profiles
(IpProfile_PlayRBTone2IP). For a detailed description of the
parameter and for configuring this feature in the IP Profiles table,
see Configuring IP Profiles on page 404.
Note:

If this feature is configured for a specific IP Profile, the settings
of this global parameter is ignored for calls associated with the
IP Profile.
Play Local RBT on ISDN
Transfer
play-l-rbt-isdn-trsfr
[PlayRBTOnISDNTransfer]
Determines whether the device plays a local ringback tone for
ISDN's Two B Channel Transfer (TBCT), Release Line Trunk
(RLT), or Explicit Call Transfer (ECT) call transfers to the
originator when the second leg receives an ISDN Alerting or
Progress message.

[0] Don't Play (default)

[1] Play
Note:

For Blind transfer, the local ringback tone is played to first call
PSTN party when the second leg receives the ISDN Alerting or
Progress message.

For Consulted transfer, the local ringback tone is played when
the second leg receives ISDN Alerting or Progress message if
the Progress message is received after a SIP REFER.

The parameter is applicable only if the parameter
