Parameter Description
coders-group
[IpProfile_CodersGroupNam
e]
SIP entity associated with the IP Profile.
The default value is the default Coder Group
("AudioCodersGroups_0"). To configure Coder Groups, see
Configuring Coder Groups on page 427.
Play RB Tone to IP
play-rbt-to-ip
[IpProfile_PlayRBTone2IP]
Enables the device to play a ringback tone to the IP side for IP-to-Tel
calls.
 [0] Disable (Default)
 [1] Enable = Plays a ringback tone after a SIP 183 session
progress response is sent.
Note:
 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.
 Digital interfaces: If the parameter is enabled and
EnableEarlyMedia is set to 1, the device plays a ringback tone
according to the following:

CAS: The device opens a voice channel, sends a 183+SDP
response, and then plays a ringback tone to IP.

ISDN: 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.
 The corresponding global parameter is PlayRBTone2IP.
Progress Indicator to IP
prog-ind-to-ip
[IpProfile_ProgressIndicator2
IP]
Defines the progress indicator (PI) sent to the IP.
 [-1] = (Default) Not configured:

Analog: Default values are used (1 for FXO interfaces and 0 for
FXS interfaces).

Digital ISDN: The PI received in ISDN Proceeding, Progress,
and Alerting messages is used, as described in the options
below.
 [0] No PI =

Analog: For IP-to-Tel calls, the device sends a 180 Ringing
response to IP after placing a call to a phone (FXS) or PBX
(FXO).

Digital: For IP-to-Tel calls, the device sends 180 Ringing
response to the IP after receiving an ISDN Alerting or (for
CAS) after placing a call to the PBX/PSTN.
 [1] PI = 1:

Analog: For IP-to-Tel calls, if the EnableEarlyMedia parameter
is set to 1, the device sends a 183 Session Progress message
with SDP immediately after a call is placed to a phone/PBX.
This is used to cut-through the voice path before the remote
party answers the call. This allows the originating party to listen
to network call progress tones such as ringback tone or other
