Ethernet capture uses TCP DUMP which is a common pocket analyzer allows users to capture TCP/IP
and other packets being transmitted or received over a network to which the IP PBX is attached. The
captured packets can be downloaded from the IP PBX system and been analyzed on your Windows
PC to display the SIP traffic details. It can be used to debug a VoIP call problem.
Path:
Maintenance -> Diagnostic -> Ethernet Capture
To capture the network traffic, you need to select the network interface according to on which the
IP PBX system is working on. Then click on
Start
button to start capturing the network traffic.
Once the process begins, the Start button will change to Stop. At this moment, you should make a call
to recur the phone call problem or ensure some other problem had recurred, so the captured network
traffic could content errors that are helpful for troubleshooting. Once done click on
Stop
button, and
the captured network traffic will be automatically downloaded.
The downloaded file could be analyzed by Wireshark or you could send the file to FS support team
for help.

Channel Monitor, technically DAHDI Monitor allows you to monitor signal level on analog channel and
record the output to a file. Recorded audio files are by default raw signed linear PCM. You can play it to
the speaker to listen to the phone call signaling on the analog channel. Or you can use a sounds editor
to visual display the audio level at both the Rx (audio Received by Asterisk) and Tx (audio Transmitted
by Asterisk).
Usually Channel Monitor can be used to capture the caller ID signaling of an FXO channel. If you are
experiencing caller ID problem you can perform channel monitor on the FXO port and then analyze
the captured packets. If needed, you can send this file to FS support for help.
Path:
Maintenance -> Diagnostic -> Channel Monitor
Before starting channel monitor, you need to select an FXO interface. Then click on Start button to
capture signaling on the selected interface.
