Citel Technologies

Citel Technologies operates as a specialist in Voice over IP (VoIP) migration, providing solutions that allow businesses to transition to IP telephony while retaining their existing investments in telecommunications infrastructure. The company was originally established in 1995 in Nottingham, UK, where it started as a developer of computer telephony integration (CTI) applications. Over the years, it has evolved, notably through the acquisition of MCK Communications in 2005, which expanded its product portfolio to better serve remote and branch offices. In 2015, the business and assets were purchased by Tortel USA, and it began operating as Citel Technologies Inc., headquartered in Amherst, New York.

The firm's business model is centered on manufacturing and selling network-edge products that bridge legacy PBX systems with modern IP networks. This approach targets small and medium-sized businesses, large enterprises, and service providers, enabling them to adopt VoIP without the high cost and disruption of a complete overhaul of their existing handsets and wiring. Citel's product line facilitates a phased migration to next-generation IP applications and hosted services. A key product is the Portico™ Telephone VoIP Adapter (TVA), which SIP-enables digital, analog, and Centrex phones, allowing them to connect to an IP PBX. By doing this, clients can extend the life of their current phone systems and avoid significant capital expenditure on new IP handsets and user retraining.

The company's offerings have expanded to include a range of managed services. These now encompass managed network services like SD-WAN and SASE, as well as next-generation security services such as SOC-as-a-Service (SOCaaS), Identity Access Management (IAM), and Zero Trust Network Access (ZTNA). Citel also provides solutions for smart buildings, cloud access control, and consulting services in software and product development. The company operates in North America and Europe, serving its clients through a network of channel partners.
