Runs on our Auerswald 5020 VoIP without problems and integrates well with the TK with the other system telephones. The extension with LCD display EXP40 does what you want. The extension for the headset is only the day so I can currently say anything yet.
The phone has all the features you need, using the Web interface, you can configure it easily.
The touch screen is pleasant to use. He is somewhat dull disturb the fingerprints not so much as in the polished screens.
The voice quality is also good so long as the HD goes along.
In my view, a really successful phone for pleasant price.
I can only recommend the Yealink.
Keep it up :) TIPTEL
PS What you should definitely consider is that the phone has no power supply. Does one need a PoE switch or a POE Single adapter, otherwise the good piece is not running namely.
PS headset: with this extension:; redirect = true & ref_ = oh_aui_detailpage_o01_s00
Does my headset:; redirect = true & ref_ = oh_aui_detailpage_o03_s01
absolutely smoothly.
Can we therefore also recommend this kombi. You can decrease the call on the headset as well as the listener. The phone will find the self-employed.
