Businesses running on legacy phone systems often face higher call costs, limited call routing, and no central oversight of communication. Grandstream IP phones and PBX systems provide UAE offices with a structured VoIP phone system built on open SIP standards, without the per-user licence fees that most enterprise platforms carry. Deployed across 150+ countries and trusted by enterprises worldwide, the brand has been connecting businesses since 2002.
This guide covers how these phones work, which models suit different offices, and what to look for when buying a VoIP phone system in the UAE.
What Is a Grandstream IP Phone Used For?
An IP phone replaces the analogue desk phone by running calls over your internet connection instead of traditional copper phone lines. This brings lower call costs, more features, and the ability to connect your entire office on one system, whether staff are on the same floor or in different cities.
Common uses in UAE offices include:
- Inbound and outbound calls from a business number
- Internal calls between departments at no added cost
- Call transfers, voicemail, forwarding, and do-not-disturb
- Video and conference calls on supported models
- Remote extensions via a mobile or desktop app
The GRP series covers carrier-grade desk phones for corporate offices. The GXP range is suited to smaller teams where budget takes priority. The GHP series targets hotels, with guest room phones and dedicated front-desk models.
Can These Phones Work With Any PBX System?
Yes. All phones in the range use SIP, an open protocol supported by nearly every VoIP platform on the market. This means the desk phones connect to third-party PBX systems, and the UCM PBX works with handsets from other SIP-compatible manufacturers.
In practice, most UAE businesses pair the IP phones with the UCM6300 PBX series. The integration is tighter, everything is managed from one interface, and there is no compatibility guesswork. But if you already have a PBX, adding these handsets to your existing setup is usually straightforward.
What Is the UCM PBX System?
The UCM6300 is an on-premise business phone system. The hardware sits in your office rather than in a cloud data centre. It handles call routing, extensions, IVR menus, voicemail, call recording, and video meetings from one unit.
What You Get With the UCM6300
- No per-user licence fees. You pay once for the hardware. There are no monthly charges per extension added later.
- Wave app included. The free Wave app lets staff take and make office calls on their mobile or laptop using the same office number. Useful for hybrid and remote teams.
- Scales without replacing. Start with a compact UCM6301 for a small team and expand to larger models as headcount grows, without swapping out the core system.
- Built-in security. TLS and SRTP encryption protect calls from interception. The system’s built-in firewall controls guard against toll fraud, a real concern for businesses running VoIP in this region.
GRP2601 vs GRP2604: What Is the Difference?
Both models sit in the carrier-grade GRP series but target different roles.
The GRP2601 is a 2-line entry phone for staff who handle a standard call volume. It supports HD audio and core call functions. The GRP2601W adds built-in Wi-Fi, making it a practical choice for offices where cabling every desk is not feasible, or for remote workers using the phone from home.
The GRP2604 supports 4 lines, has a larger display, and handles up to 4 SIP accounts. The GRP2604P adds Bluetooth. This model suits reception desks, managers, or any role juggling multiple lines at once.
For a standard office floor, the GRP2601 or GRP2602 covers most desks. Reception, senior staff, and high-call-volume departments are better served by the GRP2603P or GRP2604P.
Are WiFi IP Phones Suitable for Remote Teams?
Yes, and this is one of the stronger cases for a VoIP phone system in a distributed UAE workplace.
The GRP2601W connects over Wi-Fi and registers as a full office extension without a physical cable back to the PBX. An employee working from home appears on the office system exactly as a desk-based colleague would.
The Wave app extends any UCM extension to a smartphone or laptop. A remote team member in Abu Dhabi or Sharjah receives calls on their regular office number, transfers calls to colleagues, and sees live availability of other extensions, with no difference to the caller.
