Frequently asked questions: IP Phones

Answers to common questions about this product line, from the KDT Help Center.

Why isn't my IP phone working properly?

First check the power, the cable or connection, the settings, the network address and the software status. Then you can move on to more in-depth checks and the logs.

Open in the Help Center

Where should I start when choosing the right IP phones?

Start by defining the intended use, the number of devices, the installation environment, the capacity required and your plans for future expansion. Then choose the model and technical specifications based on what the project actually needs.

Open in the Help Center

Which technical specifications matter most for IP phones?

Depending on the project, the most important specifications are capacity, speed, compatibility, environmental ratings, management features and scalability. Basing your choice on a single figure is usually not enough.

Open in the Help Center

Is a cheaper IP phone model always the right choice?

No. The purchase price is only one factor. You also need to consider reliability, features, service life, after-sales service and maintenance costs.

Open in the Help Center

How do I work out how much capacity an IP phone system needs?

Base the calculation on the number of devices, actual usage, how long the system will be in use and how much the project is likely to grow. It is also wise to keep some capacity in reserve.
