Rugged DECT handset for mobile VoIP

The Grandstream DP735 is a ruggedised DECT cordless IP handset built for mobility across warehouses, retail floors, offices and homes. It pairs with Grandstream DP750, DP752 or DP755 base stations to extend a VoIP network without cables. The IP67-rated casing resists water, dust, cleaning chemicals and drops from 2.5 metres, while an anti-microbial finish suits shared environments.

Suits mobile workers needing durability.

This handset targets staff who move around large sites and need a device that survives rough handling, wet conditions and frequent sanitising. It supports up to 20 SIP accounts per handset and 20 lines, with push-to-talk and three-way conferencing for team coordination. Buyers who only need a stationary desk phone or who lack a compatible DECT base station should consider other options.

Handles up to 10 handsets per base

Each DP755 base station manages up to 10 DP735 handsets, delivering 400 metres outdoor range and 50 metres indoors. Talk time reaches 65 hours and standby lasts 650 hours, reducing charging interruptions. The 2.4-inch colour display, 3.5 mm headset jack, HD audio speakerphone and built-in proximity and accelerometer sensors cover most mobile telephony needs.
