Mediant 3000
Parameter Description
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.
Notes:

This parameter is applicable only to the Gateway (GW)
application (i.e., not the IP-to-IP application).

The x in the ini file parameter name denotes the trunk number,
where 0 is Trunk 1.

EMS: Play Ring Back Tone To
IP
[PlayRBTone2IP]
Determines whether the device plays a ringback tone to the IP
side for IP-to-Tel calls.

[0] Don't Play = (Default) Ringback tone isn't played.

[1] Play = Ringback tone is played after SIP 183 session
progress response is sent.
If configured to 1 ('Play') and EnableEarlyMedia is set to 1, the
device plays a ringback tone according to the following:

For CAS interfaces: the device opens a voice channel, sends
a 183+SDP response, and then plays a ringback tone to IP.

For ISDN interfaces: if a Progress or an Alerting message with
PI (1 or 8) is received from the ISDN, the device opens a voice
channel, sends a 183+SDP or 180+SDP response, but doesn't
play a ringback tone to IP. If PI (1 or 8) is received from the
ISDN, the device assumes that ringback tone is played by the
ISDN switch. Otherwise, the device plays a ringback tone to IP
after receiving an Alerting message from the ISDN. It sends a
180+SDP response, signaling to the calling party to open a
voice channel to hear the played ringback tone.
Notes:

To enable the device to send a 183/180+SDP responses, set
the EnableEarlyMedia parameter to 1.

If the EnableDigitDelivery parameter is set to 1, the device
doesn't play a ringback tone to IP and doesn't send 183 or
180+SDP responses.

This parameter can also be configured in an IP Profile.

Transfer
[PlayRBTOnISDNTransfer]
Determines whether the device plays a local ringback tone for
ISDN's Two B Channel Transfer (TBCT), Release Line Trunk

originator when the second leg receives an ISDN Alerting or
Progress message.

[0] Don't Play (default)

[1] Play
Notes:

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.

This parameter is applicable only if the parameter
SendISDNTransferOnConnect is set to 1.
