Embrace SIP Trunking for Enhanced Efficiency and Cost Savings

SIP Trunking offers the world-class business telephony you have come to depend on, while consolidating multiple channels into a single IP network, for enhanced performance, resilience, and cost savings. Simple to deploy, SIP trunking provides continuous service and futureproofing against industry changes, ensuring telephony remains a key element of effective communication and collaboration.

As we get closer to the PSTN shut-off in 2025, SIP Trunking and ISDN replacement services are even more important for organisations that still rely on traditional business phone systems and analogue lines to power internal and external communications. Utilising SIP Trunking as a PSTN replacement ensures continuity can be maintained throughout the transition period, and staff can maintain business-as-usual and focus on exceptional service quality.

In addition to helping prepare business for the transition from PSTN to pure IP based telephony, the adoption of SIP trunking provides many advantages in flexibility and service resilience over local exchange-based ISDN, leveraging Exponential-e’s SIP Trunking service, Unified Communications and Customer Engagement platforms to power world-class customer contact strategies and effortless collaboration between colleagues.

FAQs

SIP Trunking is a VoIP technology that allows businesses to make and receive phone calls over the internet instead of traditional phone lines, offering a cost-effective, scalable, and flexible communication solution that supports voice, video, and other multimedia services.

SIP Trunking uses internet connections instead of physical phone lines, offering greater flexibility, scalability, cost savings, enhanced features, and geographic flexibility compared to traditional phone systems. It allows for easier integration with business software, better reliability through redundancy, and broader international reach, but requires a reliable internet connection to maintain call quality.
