The high-end IP telephone GRP2616 was designed for the requirements of service providers, offers zero-touch provisioning, simple management and is therefore ideal for mass provisioning. The GRP2616, like all GRP models, impresses with its clear design and optimal functionality. The phone offers 6 lines for up to 6 SIP accounts and already has a WLAN and Bluetooth interface integrated. The other features also leave nothing to be desired; in addition to 48 virtual multi-function keys (MPKs), dual gigabit ports, a headset connection and much more are available. The highlight are the two LCD displays, all call information is shown on the main display, the second display provides BLF, presence, speed dial, etc. All models in the GRP series offer a high level of security (Carrier Grade Standard), including secure boot, dual firmware images and encrypted data storage. For cloud provisioning, the GRP2616 GDMS (Grandstream Device Management System) supports the central solution for provisioning, configuration, upgrade, and installation. The GRP2616 is a sensible and powerful extension to the high-end GRP26xx product line and offers users and service providers the highest level of performance, security, reliability and convenience.
