IP Phone Grandstream Networks DP722 Black Grey
The Grandstream Networks DP722 Black Grey is a wireless DECT IP phone designed for business and professional environments. It features a compact form with a 1.8-inch (4.57 cm) TFT display at 128 x 160 pixels, support for up to 10 SIP accounts/lines, and wide codec compatibility including G.711, G.722, G.729 and OPUS. The handset provides hands-free speakerphone operation, an integrated answering machine function, and a color scheme in black and grey. Its radio design offers a maximum indoor range of up to 50 metres and outdoor range up to 350 metres, enabling mobility within offices and small campus areas.
The DP722 combines multi-line SIP support and modern audio codecs to deliver clear voice quality and interoperability with SIP PBX systems. The small TFT display and intuitive keypad enable straightforward call control and configuration. Built-in speakerphone and answering machine functions increase flexibility for single users or small teams. The wireless DECT connectivity provides roaming within the specified indoor and outdoor ranges, reducing the need for wired handsets while maintaining call reliability.
Power on the DP722 handset and register it to a compatible DECT base station or IP DECT system according to the base manufacturer instructions. Use the handset menu and keypad to configure SIP account settings, network parameters and audio preferences. Place or receive calls using the handset keys or the speakerphone. Access stored messages and the answering machine from the handset menu. For optimal audio, select an appropriate codec in the device settings that matches your PBX or SIP provider capabilities.
Position the DECT base station centrally and clear of large metal objects to achieve the published indoor and outdoor ranges. Use G.722 or OPUS codecs where supported for improved audio quality, and reserve G.729 for bandwidth-constrained links. Charge the handset fully before first use and ensure firmware on both handset and base are kept updated to maintain compatibility and security.
