About Us | Contact Us

Callmaster Ltd was formed as a family business in 1979. Originally operating in the emerging telecoms equipment market prior to deregularisation in the early 80's, Callmaster was one of BTs first resellers and servicing agents for Mobile phones (In those early days a phone was the size of a suitcase). Through the 80s and 90s, Callmaster expanded their portfolio to include early PBX and Key Systems before embracing the move towards more IP based systems utilizing existing data links between sites. Our portfolio now incorporates line provision and reduced call costs for both fixed, mobile and network links enabling customers to enjoy the benefits of a single point of contact and a single bill for their entire infrastructure.

To simplify navigation of our site, we have split the business areas into four distinct sections:

• Connectivity: BT Lines, Call Cost Reduction, Mobile Phone Airtime
• Office Infrastructure: Networking for LANS and WANS
• Fixed Telephony: Telephone Systems
• Mobile Phones
