Insights

Businesses and busy households often need phone systems that keep pace with people moving between rooms, floors, or work areas rather than staying tied to a desk. The DP750 addresses this by pairing with up to 5 DP720 handsets over a long-range DECT connection, letting users carry a handset with them while remaining reachable on the same phone system.

Its support for a shared SIP account across all handsets, combined with flexible ring group modes such as Circular, Linear, Parallel, and Shared, means incoming calls can be routed intelligently across the team, rather than being tied to a single handset or desk phone.

Is It Right?

This DECT base station is a great choice if you:

• Need cordless VoIP coverage across a large indoor or outdoor area.
• Want to equip a team of up to 5 users with cordless handsets.
• Require multiple SIP accounts and concurrent call support.
• Prefer PoE-powered equipment for simpler installation.
• Already use, or plan to use, Grandstream’s UCM series IP PBX.

You may want to consider another option if you:

• Only need a single fixed desk phone rather than cordless handsets.
• Require support for more than 5 handsets on one base station.
• Need built-in video calling, since the DP750 is an audio-only DECT system.
