Cut the Cord. Your Business Phone Should Move With You, Not Wait at Your Desk.
Grandstream WP series WiFi phones, DECT handsets, and softphone apps like Grandstream Wave and 3CX give your team enterprise-grade voice and video communication anywhere there's a network signal — on the factory floor, in the hotel lobby, across the city, or on the other side of the world.
Your Phone System Was Built for 1995. Your Business Wasn't.
Traditional desk phones are brilliant — when you're sitting at your desk. The moment an employee steps into a meeting room, walks the warehouse floor, drives to a client site, or works from home, that expensive PBX extension becomes completely useless. Calls are missed. Business is lost. Customers are frustrated.
The modern answer to this is mobility — building a phone system where the extension follows the person, not the desk. And there are now three excellent ways to achieve this: WiFi IP phones (like the Grandstream WP series), DECT cordless handsets (like the Grandstream DP series), and softphone mobile apps (like Grandstream Wave and 3CX) that run on your existing smartphone or laptop.
"A WiFi IP phone or a softphone app gives every employee the full power of your business PBX — call transfer, voicemail, conference calls, shared directories, IVR access — from anywhere they have a WiFi or mobile data connection. It is not a workaround. It is the future of business telephony."
At TekkPak Technologies, Pakistan's authorized Grandstream reseller, we help businesses across Pakistan build truly mobile communication systems. Whether you need WiFi handsets for a hospital ward, DECT phones for a hotel, or softphone apps for a distributed sales team — our product range and expertise covers every scenario.
In this guide, we'll walk through the Grandstream WP series WiFi phones in detail, compare them with DECT and softphone options, explain the business benefits of each, and help you identify which mobility solution is right for your environment.

Turn Any Smartphone or Laptop Into a Business Extension
No hardware required. No extra cost per extension. Your team's personal device becomes a fully featured PBX handset.
Grandstream Wave is the official softphone and unified communications app that pairs seamlessly with the Grandstream UCM6300 PBX. Once registered, it delivers the full PBX experience — HD voice, video calls, team messaging, call history, and voicemail — on any iOS or Android device.
Configuration is automatic when used with UCM6300: the PBX pushes extension settings directly to the app via QR code scan, eliminating manual SIP configuration for your employees.
The 3CX app is one of the most polished and feature-rich softphone clients available. Beyond standard voice calls, it provides built-in video meetings, live chat, WhatsApp Business messaging, CRM click-to-call, and a web client — all in a single unified interface.
For businesses using 3CX PBX, the app is the primary communication hub for remote and office employees alike, with push notifications ensuring calls are never missed even when the app runs in the background.
Grandstream UCM6300 and 3CX are fully compatible with any standards-based SIP softphone. If your team already uses Zoiper, Linphone, MicroSIP, or another SIP client, they will work out of the box — simply register the UCM6300 extension credentials and you're live.
This open-standards compatibility is one of the core advantages of IP telephony: you are never locked into a proprietary app ecosystem.
9 Ways Wireless VoIP & Softphones Transform Your Business
Zero Missed Calls
When your business phone follows your employee — on a WiFi handset, DECT phone, or softphone app — calls reach the right person whether they're at their desk, in a meeting, or on the factory floor.
One Number Everywhere
Customers always dial the same business number. It rings simultaneously on a desk phone, a WiFi handset, and the employee's softphone app. Whoever picks up first takes the call — no call forwarding complexity.
Full Floor & Site Coverage
Grandstream WP series WiFi phones roam seamlessly between WiFi access points, maintaining uninterrupted calls across large warehouses, factory floors, hospital buildings, and campus environments.
All-Day Battery Life
The Grandstream WP825 delivers up to 13 hours of continuous talk time and 450 hours on standby — powering through an entire double shift without needing a charge.
Global Reach — Zero Cost
A softphone app registered to your UCM6300 or 3CX PBX works anywhere your employee has internet. Internal calls between all global extensions cost nothing.
Emergency & Safety Features
The Grandstream WP825 includes a dedicated emergency SOS button that can trigger calls or alerts to predefined numbers — critical for lone workers, healthcare staff, and security personnel.
Encrypted Calls on Every Device
All Grandstream WP phones and the Wave app support SRTP voice encryption and TLS signalling — the same standards used by enterprise desk phones — even over public WiFi.
Zero-Touch Provisioning
Grandstream UCM6300 auto-provisions WP series phones and the Wave app instantly. Add an extension on the PBX, scan a QR code, and the device is fully configured — in under 60 seconds.
Voice + Video + Chat, Unified
The Grandstream Wave app and 3CX client unify voice calls, video meetings, instant messaging, and file sharing in a single interface — so mobile and office staff communicate with equal richness.

Industrial-Grade Ruggedness
The WP825 is dust-proof and waterproof — safe on factory floors, loading docks, kitchens, and outdoor sites where conventional phones would fail.
Dual Connectivity on WP825
The WP825 carries both enterprise WiFi and a 4G LTE SIM — so it automatically fails over to cellular when leaving WiFi coverage, keeping calls alive.
Auto-Provision Setup Time
Grandstream UCM6300 auto-provisions WP phones and Wave app via QR code. New employee deployment takes under 60 seconds from unboxing to live call.
Which Businesses Benefit Most from Wireless VoIP Mobility?
Hotels & Hospitality
Housekeeping supervisors, concierge, engineering staff, and F&B managers carry WP820 or WP825 WiFi phones throughout the property. A single UCM6300 PBX manages all room phones, staff handsets, and the front desk.
Hospitals & Healthcare
Nurses, doctors, and ward staff carry WP series handsets that ring directly to their extension. The emergency SOS on WP825 triggers code-alert calls. All calls are encrypted on the hospital's own UCM PBX.
Factories & Warehouses
IP67-rated WP825 handsets survive oil, dust, and water on production lines. Push-to-talk groups let shift supervisors broadcast instantly to all floor staff. DECT base stations cover areas where WiFi is impractical.
Field Sales & Account Teams
Sales reps visiting clients or travelling use the 3CX or Grandstream Wave softphone app on their smartphones — appearing with the company's main number to every prospect they call, regardless of city.
Schools & Universities
Teaching staff carry WP810 WiFi phones between classrooms, labs, and sports facilities. Admin offices use DECT handsets. Softphone apps keep department heads reachable even when off-campus.
Retail & Shopping Centres
Floor managers and stock room staff communicate on WP820 WiFi handsets across multiple floors without cell dead zones. The UCM6300 PBX provides queue management for the front desk without additional software cost.

Mobility Is No Longer a Feature. It's the Foundation.
The most advanced desk phone in the world is useless the moment an employee stands up. Wireless IP phones and softphone apps remove that limitation entirely — turning your entire business communication system into something that moves fluidly with your team, across every environment they work in.
The Grandstream WP series — particularly the flagship WP825 — represents the state of the art in enterprise WiFi telephony: IP67-rugged, Android-powered, 4G-capable, and auto-provisioned by the UCM6300 PBX in under a minute. Paired with Grandstream Wave or the 3CX mobile app, your team gains unified voice, video, and messaging on every device they carry — at no additional monthly cost.
