We had a touchscreen go bad on one and another I forget exactly. They've been good phones. I love how you can use a USB headset. I just wish it would remember the volume for USB headsets like it does for the phone mini-plug ones.

COMPRAMOS VARIOS DE ESTOS PARA UN CLIENTE EN PANAMÁ Y DECIA QUE SE VEIAN Y TRABAJABAN COMO NUEVOS .... Y CUANDO LLEGARON HEMOS PASADO LA PENA DE NUESTRAS VIDAS CUANDO SE DESTAPARON Y ESTABAN RAYADOS, DECOLORADOS Y HASTA CON PIEZAS PARTIDAS. DIOS MIO QUE INCREIBLE, NOS TOCÓ COMPRARLOS NUEVAMENTE COMPLETAMENTE NUEVOS Y TODO SALIÓ MAS CARO DE LO QUE PENSAMOS ... LO BARATO SALE CARO

This is my 4th one for my small business. They are great phones. I like the soft keys and the USB port so you can have pictures display as a screensaver.

So far I love this phone, after updating configuration I am just blown away with the possibilities. I am currently using my Steel Series Siberia 840 to vvx 500 which is connected via usb to the steel transmitter. I also tried logitech H390 headset and it worked decent. Also if you have a headset thats not usb friendly you can use a USB sound card dongle which has the 3.5 or 2.5 jacks for mic and audio then the phone will recongize its a headset outlet. Polycom states that plantronics, senheiser & Jabra are the only compatiable headsets which is not true. Other headsets will work/ function but some features might not work for example the wireless volume button on the headset or mic level options. Anyways hope this info is useful. :)

Latest HD voice protocols for the best quality. Value priced compared to Cisco.Takes up less space on the desk than Cisco too. Wish it had bluetooth in this same size.(Bluetooth is had in the larger 600 model)
