GHP610/GHP610W and GHP611/GHP611W are compact IP phones with an HD speaker on the handset, 2 SIP accounts/lines, 10 speed dial keys and 3 programmable keys. These simple IP phones, part of the GHP hotel phone series, are also ideal for hospitals, apartments, dormitories, retail and more. This series includes 2 models with built-in support for dual-band Wi-Fi (GHP610W and GHP611W), provides a three-way voice conference, supports the OPUS full-band voice codec and has an advanced jitter resistance algorithm that allows loss of up to 30% of packets without compromising voice quality. The GHP series is supported by the Grandstream Device Management System (GDMS), which provides a centralized
