However, in many cases only individual devices are defective or have become unsightly, particularly indoors. For this type of case, Siedle offers a special variant of the current design line, the exchange telephone HTA 811. In terms of its design and function, it corresponds to the standard in-house telephone, but can be integrated seamlessly into an existing 6+n system.
Benefit: In the event of a defect, it is not necessary to exchange the entire system, only the affected call station. A difference that can save thousands of Euros - our contribution to investment security.
