Telephony Tone Parameters

Defines the maximum number of concurrent call parties that have been placed on hold to which the device can play Music on Hold (MoH) that originates from an external media player.

The maximum is 20. The default is 0.

For more information, see Configuring MoH from External Audio Source.

Note:

Enables the device to handle incoming re-INVITE messages with the "a=sendonly" attribute in the SDP, in the same way as if an "a=inactive" is received in the SDP. When enabled, the device plays a held tone to the Tel phone and responds with a SIP 200 OK containing the "a=recvonly" attribute in the SDP.

Note: The parameter is applicable only to analog interfaces.

Defines the maximum duration (in seconds) that the dial tone is played.

Analog interfaces: FXS interfaces play the dial tone after the phone is picked up (off-hook). FXO interfaces play the dial tone after the port is seized in response to ringing (from PBX/PSTN). The valid range is 0 to 60. The default time is 16.

Note:

Defines the duration (in msec) of the confirmation tone. A stutter tone is played (instead of a regular dial tone) when a Message Waiting Indication (MWI) is received. The stutter tone is composed of a confirmation tone (Tone Type #8), which is played for the defined duration (StutterToneDuration) followed by a stutter dial tone (Tone Type #15). Both these tones are defined in the CPT file.

The range is 1,000 to 60,000. The default is 2,000 (i.e., 2 seconds).

Note:

Determines whether the device plays a busy / reorder tone to the PSTN side if a Tel-to-IP call is rejected by a SIP error response (4xx, 5xx or 6xx). If a SIP error response is received, the device seizes the line (off-hook), and then plays a busy / reorder tone to the PSTN side (for the duration defined by the parameter TimeForReorderTone). After playing the tone, the line is released (on-hook).

Note: The parameter is applicable only to FXO interfaces.

Defines the duration (in seconds) of the hotline dial tone. If no digits are received during this duration, the device initiates a call to a user-defined number (configured in the Automatic Dialing table - TargetOfChannel - see Configuring Automatic Dialing).

The valid range is 0 to 60. The default is 16.

Note:

Global parameter defining the duration (in seconds) that the device plays a busy or reorder tone before releasing the line.

You can also configure the feature per specific calls, using Tel Profiles (TelProfile_TimeForReorderTone). For a detailed description of the parameter and for configuring the feature in the Tel Profiles table, see Configuring Tel Profiles.

Note: If the feature is configured for a specific Tel Profile, the settings of the global parameter is ignored for calls associated with the Tel Profile.

Defines the delay interval (in seconds) from when the device receives a SIP BYE message (i.e., remote party terminates call) until the device starts playing a reorder tone to the FXS phone.

The valid range is 0 to 60. The default is 0.

Defines the duration (in seconds) of the reorder tone played to the Tel side after the IP call party releases the call, for the Cut-Through feature. After the tone stops playing, an incoming call is immediately answered if:

The valid values are 0 to 30. The default is 0 (i.e., no reorder tone is played).

Note: To enable the Cut-Through feature:

Determines whether the device plays a comfort tone (Tone Type #18) to the FXS /FXO endpoint after a SIP INVITE is sent and before a SIP 18x response is received.

Note: The parameter is applicable only yo analog interfaces.

Defines the duration (in seconds) for which the offhook warning tone is played to the user.

The valid range is -1 to 2,147,483,647. The default is 600.

Note:

Determines the playing method of the ringback tone to the Tel side.
