Sheffield's manufacturing sector relies heavily on phone communication — for supplier orders, customer enquiries, logistics coordination and emergency calls to the factory floor. Yet many South Yorkshire manufacturers are still running legacy ISDN lines that cost far more per channel than modern SIP trunks, and which will stop working entirely when BT switches off the PSTN network in January 2027.
Businesses across Sheffield in manufacturing, professional services, technology, retail and education rely on Telexico for SIP Trunks. We cover Rotherham, Barnsley and all surrounding areas — from £4.99/channel.
