Why Go with Britannic, the best SIP Trunking Provider for Businesses?
The UK is switching off ISDN and PSTN services between 2025–2027. Your current landline-based systems will stop working, and many businesses are still using rigid, traditional PSTN or SIP solutions that:
- Depend on external support for changes
- Lack flexible disaster recovery options
- Expose you to fraud and spoofing
- Provide poor transparency and control
- Lack modern value added network based applications
NetX solves all of these challenges - and more - in a single, future-ready platform.

Need Help With Direct Routing?
NetX gives you full visibility of your voice traffic, but many businesses also need to route calls into collaboration platforms like Microsoft Teams, Zoom and Google Voice. NetX Direct Routing enables that integration, ensuring your calls flow smoothly across different systems.
