Grandstream UCM6208 IP PBX with 8 FXO Ports and 800 Users

The Grandstream UCM6208 is the largest model of the UCM6200 series, with 800 users, 100 concurrent calls, 8 FXO ports for landlines and 2 FXS ports for analog phones. It fits businesses that rely on many landlines and want a rack-mount IP PBX.

====

The Grandstream UCM6208 is the largest model in the UCM6200 series, and its strength is eight FXO ports that take eight landlines directly. It registers 800 users, carries 100 concurrent calls and adds two FXS ports for analog phones and fax. It suits companies that still depend on a lot of landlines and want to move internal extensions to IP.

Grandstream lists the UCM6200 series in its end-of-life product archive; its current on-premise PBX line is the UCM6300 series.

Grandstream UCM6208 specifications

• 800 users (registered SIP devices) and 100 concurrent calls.
• 8 FXO ports and 2 FXS ports with lifeline.
• Up to 200 SIP trunk accounts.
• Gigabit WAN and LAN ports with PoE Plus.
• USB port, SD slot and a 128×32 LCD.

Eight landlines on one box

If your company has separate landline numbers for sales, support and administration, all of them plug into the PBX with no separate FXO gateway. Incoming calls go to extensions or an IVR, and outgoing calls use whichever line is free. The two FXS ports can run a fax machine and an emergency handset, both covered by lifeline during a power cut.

Conferencing, recording and call center

The UCM6208 offers up to 6 password-protected conference bridges, each with up to 32 participants from internal phones or outside lines. It includes a 5-layer IVR, queues with ACD and in-queue announcements, call recording and CDR. Browser-based WebRTC calling is supported for up to 50 simultaneous calls.

Network and installation

The two Gigabit ports run in switched, dual network or router mode, so voice can sit on a different network from data if you prefer. The chassis measures 440 × 185 × 44 mm, weighs 2.23 kg and goes in a 19-inch rack or on a desk. Calls are protected with SRTP and TLS, and management runs over HTTPS and SSH.

Where the UCM6208 fits in Saudi Arabia

• Sales and distribution companies with several well-known landline numbers on one PBX.
• Recruitment and travel offices that need an IVR and a customer call queue.
• Factories and warehouses with office extensions and a fax on an FXS port.
• Sites already running a UCM6208 that want to add capacity or standardize branch hardware.

Compatibility

The UCM6208 works with Grandstream phones and any standard SIP phone, and it provisions Grandstream devices automatically from its web interface. For extra analog handsets, add an ATA such as the HT802. The GRP2601P is a simple PoE desk phone for staff extensions, powered from a switch such as the GWN7802P.

Recording and storage

Call recordings and voicemail are saved to an SD card or USB drive, and the CDR log shows every call with its time, duration and trunk, which helps when reviewing a sales team or checking a line bill.

UCM6208 or UCM6308?

The UCM6308 belongs to the newer generation: 3,000 users and 450 calls, 8 FXS ports instead of 2, three Gigabit ports, a 64-layer IVR, video meetings and the Wave app. Both have 8 FXO ports. For a new deployment, compare the UCM6308 or UCM6304; pick the UCM6208 when you already run the same model and want matching hardware.
