Grandstream GXP1625
2 lines, 2 SIP accounts, 2.95 in backlit LCD, PoE, 10/100 Mbps
The basic desk phone for general office extensions. It powers from the switch, so there's no adapter under every desk.
Most business phone platforms charge you per extension, every year. The Grandstream UCM6300 doesn't. You buy the PBX once and add users up to what the model is rated for, so a fifty-desk office in Muscat pays for hardware, not a license that grows every time you hire.
Nine product families, 40 models. Each family has its own page with a spec comparison and a block for every model.
These are the Grandstream model numbers people in the Gulf search for by name. Each one links to its full spec block.
2 lines, 2 SIP accounts, 2.95 in backlit LCD, PoE, 10/100 Mbps
The basic desk phone for general office extensions. It powers from the switch, so there's no adapter under every desk.
Up to 1,000 users, 150 concurrent calls, 4 FXS and 4 FXO ports, audio only
The PBX for a voice-only office that has outgrown a small system. It costs less than the UCM6304 because it drops video.
2 lines, 4 SIP accounts, 2.41 in backlit LCD, PoE, 10/100 Mbps
The volume extension phone. It's the one we quote most when a whole floor needs handsets and no one needs a color screen.
Up to 500 users, 75 concurrent calls, 1 FXS and 1 FXO port, video calling
The entry PBX in the series. It's right for a single office with up to a few dozen desks and room to grow.
12 line keys, 6 SIP accounts, 4.3 in color LCD, Gigabit, PoE, Bluetooth
The operator and reception phone. It takes up to four extension modules, so one person can see the whole office's line status.

A SIP trunk is your outside line delivered over the internet connection instead of copper. The UCM6300 registers to SIP trunks from Omantel and Ooredoo the same way it registers any standard SIP provider, so you aren't tied to one carrier for the life of the system.
Before configuration starts, get three things from your carrier: the trunk registration details (server, username, password or IP authentication), the number range you've been allocated, and the number of concurrent call channels on the contract. That last one matters. The PBX can only carry as many outside calls as the trunk allows, whatever the UCM model is rated for.
If you still have analog lines, most UCM models have FXO ports for them, which makes a staged move easier. Analog phones and fax machines connect through the FXS ports or a GXW4200 gateway.
A word on cordless. The W models in this range are Wi-Fi desk phones for desks you can't cable, not handsets for staff who walk around. For roaming staff on a large site, DECT is usually more reliable than Wi-Fi handsets, because Wi-Fi roaming across a big steel building is harder than it looks and a dropped call on a warehouse floor is a real problem. DECT isn't part of the range listed here, so tell us if you need it.
Offices and head offices are the bulk of it: a UCM, GRP handsets on most desks and a GXP2170 or GRP2670 at reception. Multi-branch companies add a UCM per site or peer them together.
Hotels in Muscat and along the Salalah resort strip use the GHP room phones, with the UCM handling wake-up calls. Contact centers lean on the UCM's call queues and call recording. Schools and campuses use SIP speakers for paging, and warehouses combine paging with outdoor GWN access points for yard coverage.
Not on the UCM6300 PBX itself. You buy the hardware and add users up to the rated capacity of the model, with no per-extension license on top. Optional cloud services such as UCM RemoteConnect have their own plans, so ask us which ones your setup actually needs.
It depends on the seat count, the handset mix and whether you need analog lines on the PBX. Most systems are quoted as a project. Send us the number of users, the number of sites and the handsets you have in mind and we'll price the whole list.
Yes. The UCM6300 is a standard SIP platform, so it registers to SIP trunks from Omantel and Ooredoo. You'll need the trunk credentials and number range from your carrier before configuration starts.
Usually, yes. Number porting is arranged with your carrier, Omantel or Ooredoo. The UCM also has FXO ports on most models, so existing analog lines can connect to it during a staged move.
The UCM6301 supports up to 500 users and 75 concurrent calls, the UCM6304 up to 2,000 users and 300 calls, and the UCM6308 up to 3,000 users and 450 calls. The audio-only UCM6304A and UCM6308A support 1,000 and 1,500 users.
Elite Infotech supplies the hardware and specifies the system with you. Installation, configuration and commissioning go through our integrator and reseller network, and warranty and RMA are handled through us.
The compliant route for a business phone system is SIP trunking from a licensed operator such as Omantel or Ooredoo, connected to your own IP PBX. Check the terms of your service with your carrier before you plan the system.
Both have 4 FXS and 4 FXO ports and three Gigabit PoE+ ports. The UCM6304 supports up to 2,000 users and 300 concurrent calls with video calling and video meetings. The UCM6304A is the audio-only version, with up to 1,000 users and 150 concurrent calls.
Send the seat count, the number of sites and the models you have in mind, or just a rough brief. We'll specify the system with you and quote the full list, not the cheapest line item.
