Excellent phones!! Love it using it for my office Read more

Purchased these phones to use with VirtualPBX, a better price here on Amazon. Programming was very simple because the provider has an auto-provision link. After provisioning, the provider's configuration locked the phone, which prevented some basic customization such as settings for the power light, shared directory setup, web server interaction and many other advanced configuration options. We had an issue with the power light flashing after the phone went into the sleep mode, which was cured by a simple change to the "local" configuration file. Adding these settings to the local configuration stopped the annoying blinking: features.power_saving.power_led_flash.on_time = 0 features.power_saving.power_led_flash.off_time = 100 In order to add the settings, I had the provider "unlock" the phone, then saved the "local" configuration to a computer using the phone's web interface, added the features lines above, and then reloaded the "local" configuration - problem solved. There are many custom settings accessible via the phone's web interface, which must be enabled on the administration menu of the phone. This is a really flexible phone that is well-suited to add custom call accounting and shared directory features including web server based directories and LDAP directories. We live in an area that has poor cell connectivity, no land lines, and high latency Internet most of the time. We have tried microcells, computer soft phones, wifi calling on our cell phones, you name it. But, our internet connection is pretty good most of the time, business-grade. No matter what we tried phone calls were an exercise in frustration, with poor quality. Since we switched over to using these phones and a hosted PBX the call quality has been fantastic. Clear, quiet, solid. Good duplex without that delay and headache of two people talking over each other. Operation of the phone is simple, it just works. While the receiver is not the legacy / classic "handle" type that rests perfectly on the shoulder, it is definitely not bad at all. Many phones, especially cordless, have a receiver that is impossible to rest on the shoulder -- not this one. Speakerphone and microphone work beautifully. No yelling required. I used a simple 48 volt POE injector and transformer (WS-POE-8-ENC purchased a while back on Amazon) to provide power over my Cat6 premise wiring with no issue. I did by a couple of the Yealink 5V adapters just in case, because they have a different jack than many other 5V connectors (larger). Given the cost of the 5V adapters and the messy extra cords, it would be cleaner, and about the same cost, to use a POE injector under the desk than to use the 5V adapter if the premises cannot add Power Over Ethernet wiring. The POE thing seems confusing at first - 48 volts vs. 5 volts, but the modern POE devices take what they need and regulate the power from the 48 volt supply - no issues. In this case, the phone takes 5VDC from the POE. If this phone has issues in less than three years, I will definitely update this review. Our old Panasonic phones and switch unit lasted twenty years -- they still work. This phone is a decent value and suitable replacement so far to the old system. From what I read elsewhere, support might not be so great, so these phones are definitely "on probation" for a while yet to come, review subject to change downward. The "S" means that the phone is "Skype" enabled. I didn't try Skype. The phone works just like the "G" or general model once provisioned. Starting with five stars due to value, ease of use, flexibility and excellent frustration-free call quality. Read more

Telefono molto bello e funzionale Read more

I use this handset for my business and can't stop telling everyone about it. It's great value and helps me work the way I want to. Looks great on the desk, and has every business communication feature you could ever need. Read more

Väldigt prisvärd telefon. Bra ljud och enkel hantering. Oerhört enkel att installera, men du bör ha lite förkunskaper om hur man ställer in SIP via webbgränssnitt. Lätt att ändra information i displayen. Perfekt för att koppla ett headset till den med en extra knapp för att växla till mellan lur och headset. Enda nackdelen som jag upptäckt, är att det inte går att ändra till svenska överallt i menyn. Jag kan ha missat hur man får in svenska som systemspråk, men i så fall är det i alla fall inte lätt att hitta. Har engelska som systemspråk nu. Read more
