Phonewire, Inc. "Good technology is intuitive, better technology is transparent, the best technology is invisible." Belleville Chamber member. 25+ years in telecom.

Phonewire installs and supports business and office phone systems across the St. Louis metro — O'Fallon, Belleville and the Metro East — and nationwide: on-premise and cloud PBX, VoIP and SIP lines, business texting, intercom and paging, and desk phones that stay up through internet outages by failing over to cellular. We replace end-of-life NEC, Avaya, Mitel, Toshiba and Nortel systems and move businesses off retiring POTS/copper lines, including elevator lines. Police, medical offices and surgical centers trust us with phones that can't fail. U.S.-based technicians answer every call — no offshore call centers, no bots. Office phone installation by our own crews on systems we supply.
