Phones That Work Even When Your Internet Doesn't
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.
