Free Tool for traffic monitoringq
My client have IP Phones connecting through internet and the quality is not good. Is there any software to log down the internet bandwidth / performance such that we can study the internet bandwith at the time the quality turn bad ?

Those tools tells the whole throughput of the interface, but can it tells the latency for the connection ?
Where should I monitor, on the client's network interface or interface connecting to the internet router ?
How to monitor the port if the port can't support mirroring as the port is occupied by the device ?

Any model reference for network tap ? Is it expensive ?
Any tutorial of using Wireshark to identify the latency ?

So for Cacti you don't need a mirror port, you need to configure snmp on the device i.e. switch, router, firewall..etc.. then Cacti will poll that device every minute and start charting the bandwidth utilization on the interfaces you specify. It will also show you latency between cacti and the device, but you are more concerned with latency on your voice stuff which wireshark can help with as mentioned above.

How can I use wireshark, as it search a lot of data and I have no idea how to analyze it ?

so wireshark will need a mirror port or tap. If you don't have that start with cactiez. You can monitor the bandwidth utilization of your devices with snmp. You can configure the SIP device at the provider in cacti and just monitor via icmp. That will at least give you icmp latency between the cacti server and the provider SIP trunk.
That will get you started anyway.

If you have an old hub lying around, it will get you started.

Thanks for the grade. Good luck.
SolarWinds also has a free tool that monitors IPSLA. Your voice gateway (router) has to support that feature, but if it does, you can get a wealth of information about call quality without needing to learn how to dumpster dive through a pile of data:
