Description
The GXP1615 is a simple IP phone designed for small businesses. It handles two SIP accounts and two call appearances, shows information on a 132 x 48 pixel monochrome LCD and offers three XML programmable soft keys. The full-duplex HD speakerphone and 3-way conferencing cover the everyday needs of an office. The two 10/100 Ethernet ports let you connect the computer behind the phone, and built-in PoE powers it through the network cable; a 5 V power adapter is nevertheless supplied. The RJ9 headset port accepts Plantronics EHS headsets. Calls are protected by TLS and SRTP, and automated provisioning runs through TR-069, XML files or zero configuration with Grandstream UCM PBXs.

Use and tips
The GXP1615 suits desks that make and take calls without advanced features: individual office, reception of a very small business, workshop, hotel or residence room. It sets up in minutes on an IP PBX and deploys in bulk through automated provisioning, especially with a Grandstream UCM PBX. On a PoE switch, the supplied power adapter stays in the drawer. For two dedicated line keys and a larger phonebook, see the GXP1625; for BLF keys and Gigabit, the GXP1628.
