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.

Already Have Grandstream Phones?

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.

Ready to Move to a Managed System?

If you want one company that installs, owns, and supports your entire phone system — with U.S.-based support and day-to-day changes at no charge — a Phonewire migration is the cleanest path forward.

Why Businesses Move Away from Grandstream

Support gaps. Grandstream sells through resellers — if your original installer is no longer around, finding someone with admin access to your specific configuration can be a challenge. Phonewire builds a direct long-term relationship with every client.

Per-seat licensing as you grow. Many Grandstream deployments involve per-user licensing that compounds as you add staff. Phonewire’s hybrid on-premises system uses flat annual licensing up to 200 users — no per-seat escalation.

The scavenger hunt problem. When something breaks on an existing Grandstream system, finding who owns the configuration — the reseller, the admin, the carrier — can be its own project. Phonewire eliminates this by owning the full system relationship.
