Grandstream is still manufactured — but not part of Phonewire’s current sales lineup
Grandstream phones are still being made and sold by other resellers. Phonewire does not sell new Grandstream equipment, but we do provide support for existing Grandstream customers and can help you evaluate whether staying on Grandstream or migrating to a supported platform makes more sense for your business.
Moving Away from Grandstream? Here’s What Phonewire Recommends.
Whether your Grandstream system is aging out, you’re having trouble finding support, or you’re simply ready for a modern managed phone system — Phonewire can help you evaluate your options, port your existing numbers, and transition to a fully supported platform without starting from scratch.
Why Businesses Move Away from Grandstream

Common Grandstream Problems That Trigger a Migration
Grandstream phones are popular for their low upfront cost, but businesses frequently outgrow them as reliability, support, and feature demands increase. Here are the most common reasons Phonewire clients migrate away from Grandstream.
Firmware Instability & Dropped Calls
Grandstream firmware updates have a history of introducing new bugs while fixing old ones. Businesses report dropped calls, one-way audio, registration failures, and BLF (busy lamp field) indicators showing incorrect status after updates. Phonewire clients who migrate from Grandstream consistently cite call reliability as their primary reason for switching — they can’t afford phones that work unpredictably.
Limited Manufacturer Support
Grandstream’s support model relies heavily on online forums and email tickets with multi-day response times. When a phone system issue affects your entire office, waiting 48-72 hours for a response isn’t acceptable. Phonewire’s U.S.-based support team answers in under 3 rings and resolves most issues remotely within minutes — a dramatic improvement over Grandstream’s self-service model.
No Professional Installation Available
Grandstream sells phones through distributors and expects businesses to self-install or hire independent IT contractors. There’s no manufacturer-backed installation program, no standardized configuration process, and no quality control on deployment. Phonewire handles every aspect of installation — wiring, configuration, number porting, and staff training — so the system works correctly from day one.
Audio Quality That Doesn’t Compare
While Grandstream phones technically support HD Voice codecs, their speaker and microphone hardware doesn’t match the acoustic engineering of Poly, Yealink, or Snom. Businesses that handle client-facing calls — law firms, medical offices, sales teams — notice the difference immediately. Phonewire’s recommended phone brands deliver noticeably clearer conversations, better speakerphone performance, and superior noise cancellation.
How Phonewire Migrates You Off Grandstream
Step 1: Free Migration Assessment
Phonewire evaluates your current Grandstream setup — how many phones, what features you use, which lines you have, and what’s not working. We document your existing configuration so nothing gets lost in the transition. This assessment is free and takes about 30 minutes by phone or video call.
Step 2: Custom Proposal with Phone Recommendations
Based on your assessment, Phonewire recommends the right replacement phones — typically Yealink for budget-conscious deployments, Poly for Microsoft Teams environments, or Panasonic for on-premises reliability. Your proposal includes hardware costs, installation fees, and monthly service pricing with no hidden charges.
Step 3: Same-Day Cutover with Zero Downtime
On installation day, a Phonewire technician arrives with your new phones pre-configured and tested. Your existing phone numbers port seamlessly in the background — your old Grandstream phones remain active until the exact moment the new system goes live. There is no gap, no missed calls, and no scramble. Your team receives hands-on training before the technician leaves.
