E.2.7 Adding a Reorder Tone to the CPT File
The following procedure describes how to add a Reorder tone that a PBX generates to
indicate a disconnected call, to the CPT file.
¾
To add a Reorder tone to the CPT file, take these 11 steps:
1. Make a call (using G.711) between the MP FXO, which is connected to the PBX, and
a remote entity in the IP network.
2. Capture the call using a "network sniffer" such as Wireshark.
3. Disconnect the call from the PBX side, and then wait approximately 30 seconds before
stopping the Wireshark recording.
4. In the network trace, locate the RTP stream sent from the FXO.
5. Save the RTP payload on your PC as a *.pcm file by clicking Save Payload
(Statistics menu > RTP > Stream Analysis. (Note: ensure that you select the
‘forward’ option.)
6. Open the *.pcm file in a voice recording utility such as CoolEdit.
7. Locate the tone that the PBX played to indicate the disconnected call (if such a tone
exists).
8. Locate the attributes of the tone -- its frequency and interval (on / off time).
9. In the Call Progress Tones file, add a new Reorder Tone with the attributes you found
in the previous step. Ensure that you update the numbers of the successive tones and
the total number of tones in the beginning of the file.
10. Create a Call Progress Tones.dat file using the DConvert Utility (refer to Section E.1
on page 363).
11. Load the new file to the gateway, and then reset the gateway.
