Stay reachable even when your connection goes down.
Automatic failover routes calls to mobile numbers or backup SIP routes within seconds of a connection failure. Your business stays reachable throughout any outage. UK-wide resilient SIP trunking by IP Four.

UK-wide
resilient SIP trunking with automatic failover across all UK regions
Resilience built into every SIP trunk we deploy.
Automatic Failover
If your primary internet connection fails, inbound calls are automatically routed to your configured failover destination within seconds. No manual intervention required. Your business stays reachable throughout.
Mobile Divert on Failure
Failover calls routed to mobile numbers for key staff or a central reception mobile. Callers reach a real person even when your office connection is down. Configured in advance, activated automatically.
Redundant SIP Routes
Multiple SIP routes configured across different carriers and network paths. If one route fails, traffic switches to the next available route automatically. No single point of failure in your telephony.
Geographic Redundancy
SIP infrastructure hosted across multiple UK data centres. No single data centre failure can take your telephony offline. Carrier-grade availability built into the platform from the ground up.
Failover Testing
Quarterly failover tests included as standard. We simulate a connection failure and confirm that calls route correctly to your failover destinations. You know it works before you need it.
Outage Alerting
Real-time alerts sent to your IT team and IP Four when a failover event is detected. You know immediately when your primary connection has failed and when it has been restored.
Resilience designed, tested, and maintained.
Resilience Requirements Assessment
We assess your business continuity requirements for telephony. Identify which numbers are critical, what failover destinations are appropriate, and what recovery time objective you need.
Failover Architecture Design
Design your failover configuration including primary routes, secondary routes, and mobile divert destinations. Ensure every critical number has a tested failover path.
Redundant Route Provisioning
Redundant SIP routes provisioned across multiple carriers. Geographic redundancy configured at the platform level. All routes tested before go-live.
Failover Configuration and Testing
Failover rules configured and tested in a controlled environment. Simulate connection failure and confirm calls route correctly. Document the failover behaviour for your records.
Alerting and Monitoring Setup
Monitoring configured to detect connection failures and failover events. Alert routing set up to notify the right people immediately. Escalation paths documented.
Ongoing Resilience Management
Quarterly failover tests scheduled automatically. Failover destinations reviewed annually or when your team structure changes. Resilience maintained as your business evolves.
Resilience protecting businesses across the UK.
Challenge: An Edinburgh financial services firm had experienced two broadband outages in 12 months that left them unreachable by phone for several hours each time. Clients were unable to reach their advisers during market hours.
Outcome: Resilient SIP trunking with automatic mobile failover deployed. Next outage lasted 4 hours but zero calls were missed. All key numbers diverted to adviser mobiles within 8 seconds of connection failure.
Challenge: A Bristol healthcare practice needed to ensure patients could always reach reception even during IT or connectivity incidents. Their previous ISDN setup had no failover capability.
Outcome: SIP trunking with geographic redundancy and mobile failover configured. Quarterly failover tests passed consistently. Practice manager reported complete confidence in telephony continuity for the first time.
Challenge: A Manchester legal firm had a planned office move and needed to ensure telephony remained available throughout the transition period when connectivity at the new premises was being established.
Outcome: Temporary mobile failover activated during the move period. All calls reached the right people throughout the transition. New office SIP trunks activated and tested before mobile failover was removed.
Never miss a call due to a connection failure again.
We will assess your current telephony resilience and design a failover configuration that keeps your business reachable through any outage. Quarterly tests included as standard. Free assessment, no obligation.
