Grandstream DP720 Dect Cordless VoIP Telephone,Black

This is an IP phone which means no static, wrong volume, or random touch tone noises like you get with a regular cordless phone paired with an ATA. Other advantages of IP phones include immediate display of caller ID instead of between the first and second rings, instant call initiation after dialing, a voicemail blinking light, multiple call handling, multiple account registration, and support for wideband voice quality. Other people reverted to their terrible sounding cellphones when given only desk phones, so it had to be cordless. Cordless also means it's easier to deploy where Cat6 wiring needed for desk phones is not present. The base station can be powered with either 802.3af or AC adapter. Very useful if you want to leverage an existing UPS backed PoE infrastructure to ride out blackouts or want to ceiling mount it for better coverage. Handsets charge off cradles or you can use the micro USB port on their bottoms. Opus codec is supported which is more bandwidth efficient and tolerant of packet loss than G.722 (like all CAT-iq phones it transmits G.722 over the air, so some quality loss results from transcoding G.722 to Opus and vice versa). Speakerphone function is full duplex to allow natural conversation flow. Finally it uses standard LSD NiMH AAA batteries instead of a custom NiMH pack or lithium polymer battery. No more throwing away a phone because the battery pack wore out and replacement parts approach the cost of a whole new unit! Pairing the handset to the base was straightforward, as was typing in my VoIP account credentials. Voice quality is great. Not better than a Polycom but this is half the cost of their DECT solution. You need to correct the firmware update server URL, otherwise clicking the check firmware update button is useless. There appears to be a day light savings time bug if you enable DHCP option 2 support instead of manually selecting a time zone. Otherwise I have no complaints.

I wish there was more to say. It has all the features I wanted. Setting up a global directory for all phones on the base unit to use is more work than it should be, but if you're comfortable downloading and uploading files from a web browser and using Notepad to edit files, it shouldn't be a struggle for you. Range and quality is great - base station is 2 floors away from some phones with no drop in quality.

The phone was relatively east to set up. Once I got info from my VOIP provided I was ready to go. The sound is good as I have some hearing loss. One of the main reasons I bought the phone was the headset jack (3.5mm). The only thing I don't like about the phone is that the sound of the phone ringing comes thru the headset so if you have the ringer set high your ears are going to get blasted out-no good. Time will tell if there any issues.

They don't work without a modem that you need to buy separately. I got the modem but can't login to set it up. Total waste of time n money

Once you get over the learning curve of how to provision these devices, it becomes quite easy to maintain them. This phone and a compatible micro-pbx is a good way for a small business (or tech-obsessed home) to have all the features of a full-blown enterprise voice platform at a price not much higher than a single-line cordless home phone system. Build quality certainly a step up from retail/consumer phones, but not on par with the big-name brands. Only caveat: there’s a big step from consumer viop providers and commercial SIP providers. Expect to invest some time and a little hair-pulling unless you’re familiar with the terminology and practices of SIP trunking.

While it takes a bit to set these phones up, the result is excellent. We used Vodex Communications for our VoIP service. I cannot stress enough how important it is to have a great VoIP provider. And this company is simply the best. They worked around the clock to configure these phones and my network. I would not be able to use the hardware without them. The net of this is the hardware is great but make sure you have a great VoIP provider to make everything work.

L'articolo in questione, dopo esser stato opportunamente configurato e aggiornato, ha cominciato a dare segni di cedimento dopo circa una settimana di uso intensivo. È un cordless entry level, va bene per un uso non intensivo. Ha poche suonerie e l'upload di suonerie custom non è così agevole, il volume in chiamata non è molto alto. Nel complesso buon prodotto entry level, sicuramente il prezzo non è adeguato: nella stessa fascia si trova di meglio!

Haben jetzt seit 9 Monaten fünf Geräte mit der DECT Station DP750 (und noch weiteren Tischgeräten) in Gebrauch in Kombination mit sipgate und bis jetzt läuft alles gut. Nach ein paar kleinen anfänglichen Hürden lief dann auch alles problemlos. Die Sprach-, also Ton-Qualität ist sehr gut und die Geräte sind leicht zu bedienen. Im Grunde unterscheiden sie sich hinsichtlich der Funktionen und Menüführung von den Standardgeräten die man beispielsweise von Panasonic oder Siemens kennt. Ich bin bis jetzt wirklich zufrieden und kann sie auch wirklich empfehlen. Preis-Leistungs-Verhältnis ist wirklich sehr gut.
