Summary: I bought this phone to evaluate it for my customers. This phone is great phone. Easy to configure. I had it up and running in under 5 minutes. It is a feature rich phone and has a solid feel. This is definitely the phone I will recommend to my clients. I will be buying more of these soon.
Summary: I agree with pretty much everything the other reviewer said -- this phone really isn't ready for prime time. And the support (or lack thereof) -- WOW! I opened a ticket with Grandstream about a bug in the firmware and the ticket was closed without so much as a comment.
Pros: The phone is fairly inexpensive and well-built. The screen, though small, is bright and easy to read. Ringtones can be customized with a little difficulty; the screen with a LOT of difficulty.
Cons: Buggy firmware and NO SUPPORT. The has a noticeable hiss that completely defeats the purpose of having a HD handset. If this is CNG it's WAY too loud, and there's no way to turn it off (or even down). Documentation of the customization features is incomplete, inaccurate, changes radically between...
Summary: For serious business use, I would not buy these again. The binary configuration tool is junk. XML configuration is almost totally undocumented (they don't even supply a working example file; be prepared to figure it out on your own). The built-in ringtones are totally unacceptable for business use.
Pros: Cheap Have an RJ9 jack for headsets Great audio quality and speakerphone
Cons: Poorly documented Poor support Lack critical features for enterprise use Requires a free line key to do an attended transfer
Summary: klasse Telefon zum Betrieb an beliebiger VOIP TK Anlage. Das erste Telefon war ein Testkauf um es in unserer TPU zu betreiben. Zwischenzeitlich setzen wir diese überall ein. Zu beachten ist, dass "lediglich" 2 Accounts eingerichtet werden können.
Summary: Läuft als VOIP Telefon an einer Kabel-Fritz-Box. Einrichtung war mit Hilfe eines Youtoube Videos kinderleicht. Als Tipp: admin ist nicht der Benutzer, wenn man das Gerät per Webbrowser einrichtet, sondern das Passwort mit dem man die erweiterten Optionen erreicht.
