Grandstream DP720 Cordless VoIP Phone

Le combiné annoncé comme supportant les protocoles VoIP et WIFI ne les supporte pas. Il ne fonctionne dans ces protocoles que raccordé à une base.

Bought 3 handsets and the base unit to go into a restaurant. Discovered a deal breaking limitation that’s a feature in a different environment – Each handset is treated like a separate phone. A “line” isn’t shared between handsets like an analog phone.

On an analog phone, if two handsets pick line 1 during a call, the caller and both people on the handsets can have a 3 way chat. If your on handset 1 and put a call on hold, you’ll see it listed as on hold on handset 2 and can just switch to handset 2 and take them off hold to continue talking.

On these digital phones, to do a three way call with 2 handsets, you actually have to CALL the 2nd handset, no differently than if you were calling another phone number, and conference them in. Putting someone on hold ONLY puts them on hold on THAT handset. To enable the call to be taken off hold, you have to “park” the call by dialing a code. And there will be no indicator on the other handsets to show that someone is parked. They have to be told.

For the restaurant, training employees on complicated phone use and dialing codes just is not practical. It all has to be visual and easy and obvious.

Other than that, the sound quality with RingCentral was great. The handsets use standard rechargeable batteries. The chargers are all micro-usb. The build quality felt solid. Well made good sounding very competitively priced.

But without an option to select an “Analog Equivalent” mode for simpler no training needed use, it’s not going to work in a restaurant. And likely wouldn’t work all that well at home either unless the whole family is quite tech savvy.

A little digging in the forums and I found that until recently there was a “shared” line function that worked like an analog line. But it was buggy, and from what the admins said, they just didn’t see the point of it and it was removed. Like I said, this is intended as an office system with 5 individual users, not a shared system with many people using up to 5 random cordless phones.

Don’t waste your money on these phones. We had them for a few months and the ringer was so low you could barely hear it in our office. They are easy to setup with Telzio but thats the extent of the the positives. We’d answer a call and half the time the person on the other line would just hear air. We switched to the yealink w56p. They were a little different to setup (not too bad) with Telzio but once they were up, they are awesome. Ringer on them is super load for a place like ours and the sound quality is excellent. We do use the grandstream landline phone and they work great but these wireless phones are pretty bad

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.
