Grandstream Review

By Editorial StaffLast Modified: January 5, 2018

The Grandstream UCM6510 is an enterprise-grade IP PBX system for companies, retail outlets and apartment complexes. It not only combines voice, video, data and fax applications, but also hosts security and surveillance solutions.

The unit weighs 4.8 pounds and measures 17 x 7.3 x 1.7 inches. You can mount this PBX equipment on a rack or place it on a tabletop. It has a dot-matrix LCD with a resolution of 128 x 32 pixels on its front panel. Also found on the front panel are a USB port, an SD card slot, two FXS ports, and two FXO ports for analog and PSTN phone lines. The unit also has a T1/E1/J1 port, three Gigabit Ethernet ports and LED indicators for each of these ports.

The PBX phone system runs on a quad-core Cortex-A9 processor with a clock speed of 1GHz and also comes with 1GB DDR3 RAM and 32GB flash storage. At peak performance, the ARM processor may struggle with keeping up.

For software, the Grandstream UCM6510 runs Asterisk, a free open-source PBX operating system from Digium Inc. It supports up to 2,000 PBX phones and can easily serve as a unified communications platform for big organizations. The system also supports up to 200 concurrent calls and up to eight remote teleconference sites for a maximum of 64 attendees. For videoconferencing needs, this IP PBX equipment supports major voice and video codecs and packs carrier-grade line echo cancellation. In addition, it offers strong software and hardware-based security for IP traffic, including defense against malicious attacks.

The web-based user interface makes it easy to set up and run the equipment. It automatically discovers and provisions IP and video phones and IP security cameras. Businesses with multiple offices around the globe can also set up their employees' smartphones and laptops as softphones with the IP PBX hardware. This mobility feature, as well as the advanced PBX features such as call recording, call routing, five-layer auto attendant and voicemail, comes standard with the equipment. Grandstream offers free lifetime firmware updates for the UCM6510 and does not charge licensing or subscription fees for the device's advanced features.

The Grandstream UCM6510 is a robust IP PBX solution and a well-featured all-around telephony system for businesses of all sizes. However, the manufacturer provides only a short two-year warranty for the UCM6510.
