In this section:
This feature is used to provision a tone and announcement profile, which specifies an announcement package and/or signaling tone package for the SBC to use to play announcements or signaling tones to calling or called parties. Tone and announcement profiles are assigned to ingress or egress trunk groups. Also, use this feature to provision Local Ring Back Tones (LRBT) for the SBC, which the SBC plays to callers upon receipt of an alert indication without a media stream or without an indication of in-band tones.
To associate a Tone and Announcement Profile to a Trunk Group, use following syntax:
% set addressContext <addressContext name> zone <zone name> sipTrunkGroup <sipTrunkGroup name> policy media toneAndAnnouncementProfile <profile name>
% set profiles media toneAndAnnouncementProfile <profile name> localRingBackTone signalingTonePackageState <disable | enable> flags announcementBasedTones <disable | enable> dynamicLRBT <disable | enable> forceLRBT <disable | enable> useThisLrbtForEgress <disable | enable> useThisLrbtForIngress <disable | enable> makeInbandToneAvailable <disable | enable> precedence <higher | lower> signalingTonePackage <name> toneAndAnnouncement announcementPackageState <disable | enable> announcementPackage <name> override <disable | enable> sigTonePackage <name>
The Tone and Announcement Profile Parameters are described below.
Tone and Announcement Profile Parameters
Parameter | Description |
---|---|
| Use this object to configure the Tone and Announcement Profile. |
| Use this parameter to configure LRBT settings. See Local Ringback Tone Parameters table below for parameter details. |
| This parameter configures the Tone and Announcement package.
|
To configure localRingBackTone
options, first enable the signalingTonePackageState
flag.
You must enable makeInbandToneAvailable
in order to use Local Ringback Tone (LRBT).
Local Ringback Tone Parameters
Parameter | Description |
---|---|
flags | Use these flags to enable/disable LRBT for egress and ingress trunk groups.
|
makeInbandToneAvailable | Enable this flag to insert an in-band tone indicator (OBCI in the case of ISUP) in a backward message (for example, ACM) when playing local ringback tones.
|
precedence | Set this parameter when both the ingress and egress trunk groups have a LRBT associated with them and you want to specify which trunk group has priority over the other.
|
signalingTonePackage | <package name> – Enter the signaling tone package to use for calls associated with the specified ingress and/or egress trunk group(s). |
| Enable this flag to configure a signaling tone package.

When a caller sends a SIP The SBC monitors and detects early media from the egress call leg. The SBC plays a Ring Back Tone (RBT). P-Early-Media and DLRBT
