Are layer 2 or higher switches used?
Use of repeater hubs can increase the network load, and therefore may result in degradation in speech quality.
To ensure high speech quality, use only layer 2 or higher switches. Use of layer 2 or higher switches is also
strongly recommended for connecting IP telephones.
Note
Note that the port of the switching hub that connects to the IPCMPR card should be set to operate
under "Auto Negotiation" mode.
Are Category 5 (CAT 5) or higher cables used?
When connecting network devices, make sure to use CAT 5 or higher cables. If other types of cables are used,
communications may not be carried out normally.
