💷

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 every sector use SIP trunks to reduce their monthly phone bills, add new DDI numbers instantly, and keep their existing phone system hardware while moving away from expensive legacy ISDN lines.

💷

Sheffield businesses switching from BT Business or Virgin Media typically save 35–50% on their sip trunks costs. The comparison below shows why so many Sheffield businesses choose Telexico.
