## Long description

Grandstream Networks WP816 is a wireless IP phone handset with a 1.8" (4.57 cm) TFT display and support for two SIP lines. The blue cordless handset operates on both 2.4 GHz and 5 GHz Wi‑Fi bands and is compatible with Wi‑Fi standards 802.11a/b/g/n/ac/ax. It provides wide codec support including G.711, G.722, variants of G.723 and G.729, and includes common audio processing features such as acoustic echo cancellation (AEC), automatic gain control (AGC), adaptive jitter buffer (AJB), comfort noise generation (CNG) and packet loss concealment (PLC).
Advantages
The WP816 combines dual‑band wireless connectivity and a compact TFT display in a cordless blue handset designed for SIP telephony. Support for two lines enables handling of multiple accounts or simultaneous calls. Broad codec and audio feature support improves voice clarity and interoperability with VoIP systems. The absence of an Ethernet LAN port focuses the device on wireless deployments and mobile desk or reception scenarios.
