Grandstream DP725 DECT Cordless HD Handset (DP725)

The Grandstream DP725 is a DECT cordless IP phone that allows users to mobilise their VoIP network throughout any business, warehouse, retail store or residential environment. Supported by Grandstream's DP750, DP752 and DP755 DECT VoIP base stations, the DP725 delivers a combination of mobility and top-notch telephony performance. Up to 10 DP725 handsets are supported per base station (DP755), while each DP725 supports a range of up to 400 metres outdoors (with DP755) and 50 metres indoors.

The DP725 offers 50 hours of talk time and 500 hours of standby time, with a suite of robust telephony features including support for up to 20 SIP accounts per handset (with DP755), full HD audio, a 1.8-inch colour display, a 3.5mm headset jack, a dedicated Push-to-Talk button, a speakerphone, and 3-way audio conferencing. DECT authentication and encryption technology protects calls and account information, while automated provisioning via TR-069 and XML configuration files, and Zero Config provisioning with Grandstream's UCM IP PBX series, simplify deployment.
