Grandstream — IP phone and UCM PBX manufacturer
Grandstream Networks, Inc. has manufactured IP communication hardware since 2002 from Brookline Avenue in Boston. Its range is unusually wide for a phone vendor, running from IP desk phones, DECT and analogue telephone adaptors through the UCM6300 on-premise PBX and CloudUCM, out to Wi-Fi access points, switches, routers, fixed wireless bridges, intercoms, paging and facility access systems. That breadth means one vendor can supply the phones, the network and the door intercom.

One of the few handset makers that builds the PBX too
Most manufacturers make phones and leave the system to someone else. Grandstream makes both, and the UCM line comes in three shapes: on your premises, in Grandstream’s cloud, or as software you host yourself. For a small business that wants a phone system without a monthly per-extension fee, an on-premise UCM with Grandstream handsets is a genuinely different commercial model from a hosted subscription — capital cost up front, no seat fees after. Ask a South African provider to price both ways before assuming hosted is cheaper. The rest of the range matters more than it looks: buying the Wi-Fi, the switches and the door intercom from the same vendor as the phones removes a lot of integration argument. Confirm ICASA type approval per model with your supplier. Compare providers in the cloud PBX directory.
Who Grandstream is a fit for
- Businesses wanting an on-premise PBX with no per-extension monthly fee
- Sites needing phones, Wi-Fi, switching and intercoms from one vendor
- Companies comparing a capital purchase against a hosted subscription

Can I buy directly from Grandstream?
No. Grandstream is a manufacturer and sells through channel partners. In South Africa the equipment reaches buyers through telecoms providers and resellers, who set the price and provide support.
What is the UCM6300?
It is Grandstream’s own IP PBX, running on your premises. CloudUCM is the hosted version and SoftwareUCM is a software deployment. Because Grandstream makes both the phones and the system, a single-vendor setup is possible.
Is an on-premise UCM cheaper than a hosted PBX?
It is a different commercial model rather than automatically cheaper: capital cost up front and no per-extension monthly fee, versus a lower start and a recurring seat charge. Ask a provider to price both ways for your extension count.
How long has Grandstream been trading?
Since 2002, as stated on the company’s own site, from its head office at 126 Brookline Avenue in Boston.
Is Grandstream hardware ICASA approved?
For hardware the relevant step is ICASA Type Approval, granted per model rather than to a brand. Ask your South African supplier to confirm type approval for each specific model quoted.
Why is no customer rating shown?
Grandstream is a United States manufacturer with no South African entity or claimed local Google Business Profile. A headquarters rating in Boston would say nothing about supply or support in South Africa, so WhichVoIP shows none.
