Grandstream UCM6301 IP PBX for 500 Users with Video Meetings

The Grandstream UCM6301 is the smallest model in the UCM6300 series, handling 500 users and 75 concurrent calls, with one FXO port for a landline and one FXS port for an analog phone or fax. It is made for small businesses that want an IP PBX with built-in video meetings in a wall-mountable unit.

====

The Grandstream UCM6301 opens the UCM6300 series with a wall-mountable unit that covers what a small business actually needs: 500 users, 75 concurrent calls, one FXO port for your landline, one FXS port for a fax or analog phone, and built-in video meetings. Offices, clinics and showrooms can move to a modern phone system and keep the number customers already know.

Grandstream UCM6301 key specs

• 500 users and 75 concurrent G.711 calls, of which 50 can be SRTP-encrypted.
• 1 FXO and 1 FXS RJ11 port.
• 3 Gigabit Ethernet ports with PoE+, in switched, routed or dual mode.
• 1 USB 3.0 port and an SD slot for recordings and backups.
• 270 × 175 × 36 mm footprint.

One landline, one fax, no extra box

Plenty of small companies still rely on a landline number printed on every invoice and a fax machine that receives purchase orders. The FXO port brings that line into the PBX and spreads its calls across extensions, while the FXS port powers the fax or the guard room phone. Grandstream states the ports offer lifeline capability during a power outage. Need more lines later? Add SIP trunks or an external FXO gateway.

Video meetings hosted on your PBX

Meetings run on the UCM6301 itself: unlimited rooms, up to 4 public rooms at the same time, a maximum of 75 participants in total and up to 9 video feeds per room. With H.265, H.264 and VP8 video support, your team joins from the Wave app or from a video phone such as the GXV3450, with no monthly meeting subscription.

Auto attendant and queues for reception

Build a multi-language IVR up to 64 layers deep so callers reach sales, support or accounts on their own. Queues hand out calls automatically (ACD) based on agent skill and availability, and the system records calls and sends voicemail and faxes to email.

Where the UCM6301 fits in Saudi Arabia

• Small companies and engineering offices holding video calls with clients.
• Clinics and beauty centers that want an IVR for bookings and a known landline number.
• Shops and showrooms with one landline, a fax and a few IP phones.
• Offices with remote staff connected through Wave and UCM RemoteConnect.

Compatibility, management and security

The UCM6301 zero-config provisions Grandstream devices such as the GRP2602P phone and the DP750 DECT base, and it works with any standard SIP phone. Manage it remotely from the GDMS cloud platform and connect a CRM through the API. Secure boot, a unique device certificate, SRTP, TLS and ZRTP protect calls, and Hot Standby is supported.

UCM6301 vs UCM6302 vs UCM6300A

The UCM6302 uses the same compact chassis but doubles capacity to 1,000 users and 150 calls, with 2 FXO and 2 FXS ports. The UCM6300A from the audio series is smaller still: 250 users, 50 calls, no analog ports and no video. Pick the UCM6301 when you have a single landline and want video meetings on the PBX.
