Powerful and slimline

True greatness manifests itself in little things:  The SL800H PRO is the smallest business phone from Gigaset. Its slimline design means it looks like a smartphone. Despite its short dimensions, it boasts a large 2.4” TFT colour display. This handset is lightweight and simplifies day-to-day work, also courtesy of business functions such as SUOTA, Bluetooth 4.2 and audio profiles. And the sound quality is HDSP™.

Lightweight and durable

Waiting for a call but worried about missing it? You can take this lightweight DECT handset anywhere with you. And thanks to the vibration alarm, you are guaranteed not to miss any more calls– even in noisy and stressful situations. The device runs on and on: It has a battery life of up to 15 hours of talk time. Incidentally, charging is possible using the integrated micro-USB port.

Ergonomic and excellent

There is something not quite right when people are subordinate to their working environment: It is better when work is tailored to people. The Gigaset SL800H PRO is a comfortable fit in your hand, and the ergonomic keypad and lit colour display are additional aids for day-to-day work. The harder surface is also an excellent feature, that makes the phone scratch-proof and resistant to disinfection.

Flexible and free

It is entirely up to you: With this DECT handset, you talk and make calls as you like – the classic way with handset, handsfree or with headset. The technology provides flexibility and freedom - thanks to Bluetooth 4.2 and a 3.5mm phone jack, headsets with or without cord can be used. This has no impact on quality: Even in handsfree mode you can enjoy superb HDSP™/ CAT-IQ 2.0 acoustic quality.

Secure and worthy of protection

What is private should stay private, and so the Gigaset SL800H PRO has an Hotel option. Call lists and sensitive data within a predefined time period are deleted, so other users can not access them. This is an absolute must in the hotel and catering industry in particular. The separate button for selecting audio profiles enables you to customise further this cordless phone. 

Professional and practical

The Gigaset SL800H PRO is an excellent choice for use in day-to-day work. This is because the slimline business phone is optimised for use with all professional Gigaset DECT systems. This is practical. It can also be used on CAT-iq & GAP-compatible base stations from third party vendors, both in single and multi-cell environments.

User device of an AML system

Within the context of a system for Alarm, Messaging and Location (AML), the SL800H PRO can be integrated as a user device. The receipt of text messages can provide increased security at work and optimise key workflows. The messages can be sorted by different options (such as message priority and status). Learn more about the Gigaset AML here.

Receiving Microsoft Teams calls

The SL800H PRO can be used to make and receive calls via Microsoft Teams. It is also possible to merge calls or mute them. Voicemails can be listened to, and notifications alert you to new voicemails. Joining Teams meetings is possible by entering the meeting access number directly via the handset. The prerequisite for these functionalities is that the SL800H PRO is connected to one of the newer Gigaset single or multicell systems (N610 IP PRO, N670 IP PRO, N870 IP PRO, N870E IP PRO).
