More product details
The Grandstream DP722 is a DECT handset built for small to mid-sized businesses that need wireless mobility without the cost of a full Wi-Fi phone deployment. It pairs with a Grandstream DECT base station (most commonly the DP752) and works well in single-floor offices, retail counters, small warehouses, and residential settings where running Ethernet to every desk isn't practical. Because each base supports up to five handsets, it's a natural fit for teams of a few people who share a common reception or sales line, or for a manager who roams between a desk and a back room.
This handset makes the most sense when you already use or plan to use other Grandstream gear. The seamless door control integration with the GDS series is a genuine differentiator — if your business has a front entrance with a Grandstream access device, the DP722 can act as a remote door release, which cuts out extra intercom hardware. For general VoIP use, it handles up to ten SIP accounts, so a single handset can cover multiple lines or ring groups, which is handy in a small office where one person wears several hats.
There are practical limits. Indoor range is rated at 50 metres, but that’s in open space; concrete walls, metal shelving, and electrical rooms will shrink coverage. In a multi-floor building or a large warehouse, you’ll likely need additional base stations, which adds cost and complexity. The handset also relies entirely on the base station for connectivity — if the base loses power or network, all handsets go down. For a larger team or a call centre where every second counts, a Wi-Fi phone with more scalability and roaming support might be a better long-term investment.
For Canadian businesses, the DP722 works with any standards-compliant SIP provider, including those commonly used in the GTA. The over-the-air firmware updates mean you can keep handsets current without USB cables, which simplifies support for a distributed or hybrid team. Just keep in mind that DECT frequencies are generally interference-free in North America, but if you're in a dense office tower with many wireless devices, a site survey is still wise before committing to a full deployment.
