Business Information
Phonewire designs, sells, installs, and supports business phone systems for companies across the St. Louis metro and nationwide. We provide our own on-premise and cloud PBX systems — including VoIP and SIP solutions — then handle installation, configuration, and ongoing support so your phones just work. We specialize in replacing aging or end-of-life systems from NEC, Avaya, Mitel, Toshiba, and Panasonic, and in moving businesses off retiring POTS/copper lines. Because we supply and install our own systems, we don't quote install-only or cabling-only jobs. With 25+ years in business telecom, we win because we actually show up — before, during, and long after the install.
