Telephone, PBX, and VoIP Systems
Manufacturers & Services

Even with cellphones dominating personal and business communications, there is still a huge need for wired systems, especially for in-building PBX applications. Your desk phone will likely still be around for a long, long time.

My policy is to only list companies that actually manufacture product or offer services related to the page title subject. Product distributors and sales representatives are not listed (they have their own Distributors page). This helps guarantee that each listing offers a unique product or service.
