To verify that the board is configured correctly for IP, type cgroute print.

You will probably need to change the following line in the cg6565fusion.cfg file : so that it conforms to your network addressing scheme.

Boot the CG 6565 using the oamsys.cfg and cg6565fusion.cfg files in the zip file.

For the purposes of this note, you can use the file payloadid-101.dat (in the zip file) which contains RFC 2833 DTMFs with a payload ID of 101. Click on the RTP stream that contains the DTMFs and click the Save button and save the file as, for example, dtmfstream.dat.

Once you have identified the stream, save it by going back to Telephony->RTP->Show All Streams.Below you can see a packet for DTMF 0 highlighted and below that you can see the Payload type highlighted showing that that the payload ID is 101 (telephone-event). Scroll down to verify that it contains the DTMF packets.You will now see all packets associated with that RTP stream In the main screen, to the right of the Filter box, click Apply.To verify that you have selected the correct stream, click on Prepare Filter and click Close.When the RTP Streams box appears, select the stream of interest.To list all the RTP streams by selecting Telephony->RTP->Show All Streams.Use Wireshark 1.2.5 to open the file rfc2833.pcap from the zip file.Files referenced in the procedure below are available for download in a single zip file. ctatest.exe which is a Natural Access demo program delivered with the Natural Access installation. msppsamp.exe which is a Natural Access Fusion demo program delivered with the Natural Access installation. rtpplay.exe which is a Windows utility used to play RTP streams to a designated IP address and port. Wireshark Version 1.2.5 or later which can be downloaded from the Internet. Then, using a Wireshark trace that has captured RTP streams containing the RFC 2833 DTMFs in question, we extract the stream and play it towards the CG Series Board using a tool called rtpplay.exe. In order to perform the analysis, we start by running msppsamp in order to create a Fusion channel on the Dialogic CG Series Media Board. This article describes a method for troubleshooting improper detection of RFC 2833 DTMFs in either an RTP or DS0 endpoint when using the Dialogic® NaturalAccess™ Fusion™ VoIP API.
