The Grandstream DP755 is a DECT VoIP base station designed to manage professional wireless communication within an office or business environment. It supports up to 20 SIP lines and can be paired with as many as 10 compatible Grandstream DECT handsets, making it a versatile hub for teams that need flexible mobility without sacrificing connectivity. This black unit is compact, weighing only 0.14 kg, and integrates easily into existing networks via its 10/100 Mbps Ethernet port. You can power the device using either the included AC adapter or through Power over Ethernet (IEEE 802.3af), which simplifies cabling by delivering electricity and data through a single cable. For managing contacts and history, it features a built-in phonebook for 3000 entries and a call log that tracks up to 1500 records. Communication is handled with full HD audio and a suite of telephony tools including 3-way conferencing, call waiting, forwarding, and an answering machine. Depending on the handset used, you can maintain a wireless connection up to 50 meters indoors, while outdoor range extends to 350 meters with DP720/DP722 models or 400 meters with the DP730. To keep everything running smoothly, the base station is compatible with the GDMS management system for centralized configuration.
