DESCRIPTION: Media5 Technical Support personnel asked me to enable the PCM traces. How do I do it?
POSSIBLE CAUSE: PCM traces are an efficient tool to identify problems with:
• Echo in your network
• DTMF signals
• Caller ID signals
• Fax signals (or false Fax detection)
• Message Waiting Indicator signals
• Any other analog signal
S
OLUTION: Do the following:
a. Enable the PCM traces by setting the mxDebugPcmCaptureEnable MIB variable to enable.
b. Set the destination IP address for the PCM traces in the mxDebugPcmCaptureIpAddress MIB
variable.
• This IP address does not have to be listening on ports 5001/2 - 6001/2, as it is easy to
filter out ICMP “port unreachable” messages afterwards.
• The PCM traces destination must be set so it can be recorded in a Wireshark capture
on your network, normally sent to the PC doing the capture.
c. Set the endpoint number on which to perform the PCM capture in the
mxDebugPcmCaptureEndpointNumber variable.
For more details on the PCM traces, refer to Technical Bulletin 0648 - PCM Traces.
