Grandstream DP722 DECT HD Phone

The Grandstream DP722 is the standard handset of the DP7xx DECT range — the one most cordless deployments are built from. It reaches up to 350 metres outdoors and around 50 metres indoors from its base station, which covers a shop, an office floor or a small yard comfortably.

Each handset supports up to ten SIP accounts and two concurrent calls, so one person can hold a call and take a second without a second device. A 3.5mm headset jack, a speakerphone and push-to-talk cover the usual working patterns, and full HD audio keeps speech clear.

It needs a base station. A DP722 on its own is not a working phone — it registers to a DP750 or DP752, and up to five handsets share one base. If you are starting a system from scratch, order both.

Frequently asked questions

Can I use it without a base station?

No. The handset is only half the system — it registers to a DP750 or DP752. If you are ordering a first cordless phone, make sure a base is on the order too; it is the most common thing missed.

Will it really reach 350 metres?

Outdoors with clear line of sight, yes. Indoors expect around 50 metres, and less through solid walls, between floors or across steel racking. If range is the point of the purchase, tell us the building rather than the square footage.

How is it different from the DP730?

The DP730 reaches 400 metres instead of 350 and has a larger screen. For a shop floor or an office the DP722 is usually enough; for a yard the extra 50 metres can decide it.

How many handsets can share one base?

Five, with ten SIP accounts between them. A sixth handset means a second base station.

Can two people call each other without using the phone system?

Yes — push-to-talk works handset to handset on the same base, which is useful in a workshop or a stockroom.

Is it suitable for outdoor or wet work?

It has no ingress protection rating. For weather or wash-down, look at the ruggedised DP735 instead.
