Overview

From late 2023, sales of new PSTN lines will cease and, in 2025, the UK PSTN network will be switched off. By then, all phone lines will need to have moved to a fully digital (IP) network. Like most deadlines, it will be here much faster than many expect.

Resonate offers a fully managed SIP trunking and Teams Direct Routing service. We also have a team of expert solutions architects, who can help you move to, or integrate your legacy services with, Microsoft Teams. 

Is your organisation still relying on legacy services?

  • Don’t fully understand your voice telephony estate, which might have built up over time and been managed on a site-by-site basis?
  • Can’t identify which legacy phone services you still use and whether they need to be migrated or integrated into a Teams solution?
  • Experiencing rising legacy phone bills 
  • Struggling to find a way to add or extend your service?
