What TELESIS Technologies does

TELESIS Technologies s.r.o. is a privately held Czech limited liability company founded in 1998 and headquartered in Prague, operating as a distributor, retailer, and service provider for telecommunications equipment in the Czech Republic. The company sells wholesale and retail through two e-commerce storefronts (telesis.cz and levne-telefony.cz) and supports a registered partner program for wholesale buyers, while providing installation, repair, and consulting services nationally.

The company's core offering is the proprietary PX24 series of VoIP telephone exchanges (PX24arX, PX24brX, PX24nrX, PX24mrX, PX24xrX) running on the in-house Xymphony operating system with non-blocking switching matrices and protocol support spanning analog, digital, ISDN, SIP, H.323, SS7, and V5.2.

TELESIS monetizes through one-time hardware sales (priced in Czech Koruna, roughly 491 CZK for basic phones to over 55,000 CZK for extended PBX systems), recurring service and maintenance contracts for the installed base, and consulting engagements. Customer segments span healthcare facilities, SMBs, large enterprises, and hospitality. No funding rounds, M&A activity, or disclosed financials are present in the available data; the company has 1–10 employees and operates exclusively within the Czech market.
