Cost is the reason most GCC companies start looking at 3CX and, a year later, it is usually not the reason they stay. Still, the numbers matter, so this article works through where the savings come from when a business moves from a traditional PBX or a per-seat cloud service to 3CX, and where the savings are smaller than the brochures suggest.
1. Trunking instead of lines
A legacy PBX is fed by ISDN or analogue lines from the carrier, each with a rental charge whether or not it carries a call. 3CX connects to a SIP trunk, where you buy a number of channels and pay for what you use. For an office that has been renting two PRIs to handle occasional peaks, moving to a right-sized SIP trunk is often the single largest recurring saving. Number ranges are ported, so nothing changes for customers.
2. Licensing by simultaneous calls
Cloud phone services almost all charge per user per month. 3CX charges by simultaneous calls on an annual licence. For a company with 80 staff and a realistic peak of 12 concurrent calls, the difference between 80 monthly seats and a 16SC annual licence is substantial and it compounds every year. The effect is largest in organisations with many extensions that are lightly used: warehouses, clinics, schools, hotels, retail chains.
3. Hardware you already own
3CX runs on a modest virtual machine or a small appliance. Most companies already have the capacity on an existing hypervisor. Existing SIP handsets from Yealink, Snom or Fanvil are re-provisioned rather than replaced, and where handsets are being refreshed, a mid-range IP phone is a fraction of the price of a proprietary digital handset from a legacy vendor.
4. Moves, adds and changes
The hidden cost of an old PBX is the engineer visit. Adding an extension, changing a hunt group or recording a new greeting often meant a chargeable call-out. In 3CX these are done in the web console by your own IT team or by a reseller remotely, in minutes. Over a year this line item is larger than most finance teams expect.
5. Branches and remote staff
Connecting a second site to a traditional PBX meant a second PBX or a tie-line. With 3CX, a branch office registers its phones to the same system over the internet or an SD-WAN link, and calls between sites are internal extension calls at no cost. Staff working from home use the same extension on a laptop or mobile app, with no additional service.
6. Conferencing and chat included
Video meetings, screen sharing and website live chat are part of 3CX rather than separate subscriptions. Companies that were paying for a meeting tool and a chat widget on top of a phone service usually retire at least one of them.
Where the savings are smaller
Be realistic about three things. First, someone has to administer the system; if there is no IT staff, budget for a reseller support contract. Second, call quality depends on the network, so a firewall with proper QoS and, for larger sites, a dedicated voice VLAN are not places to economise. Third, if you self-host in the cloud, the VM has a monthly cost – small, but not zero.
A worked example
A trading company in Dubai with 45 staff across a head office and a warehouse was paying line rental on two PRIs, a maintenance contract on a digital PBX, and a separate video-meeting subscription. After moving to a hosted 3CX instance with an 8SC licence, a SIP trunk sized to its actual peak, and 40 Yealink handsets supplied through Zen, the recurring communications spend fell by more than half and the maintenance contract was replaced by a reseller support agreement at a lower rate. The warehouse phones became extensions of head office at no extra cost.
Getting a like-for-like comparison
Zen can produce a comparison for your business from your current carrier bill and PBX maintenance invoice. As the 3CX distributor for the UAE and GCC, we supply the licence, the handsets and the gateway if one is needed, and we work with a network of certified resellers who implement and support the system.
