—— Customer Story ——
Carrier-grade voice in Europe, delivered in months, not years
A global enterprise CX platform needed 99.99% uptime and in-jurisdiction data processing for regulated European customers. SignalWire’s Dedicated Real-Time Region made it possible, without years of in-house engineering.
—— The Challenge ——
A voice platform gap that threatened enterprise growth
Four-nines uptime. Enterprise contracts won. Years of build time saved.
Before: Shared Cloud
99.95% availability ceiling — over 4 hours of potential downtime per year
No path to single-tenant isolation
Voice traffic crossed jurisdictional boundaries
3–7 years of internal platform engineering required
Enterprise contracts at risk
Support escalations consumed engineering time
After: Dedicated Real-Time Region
99.99% availability — roughly 22 minutes maximum downtime per year
European voice launched in months, not years
Tier-1 carrier wins and tens of thousands of agents onboarded
Latency and packet loss reduced through in-region processing
Support escalations dropped with proactive monitoring
A scalable blueprint for future dedicated-region customers
A Dedicated Real-Time Region: Single-Tenant, In-Country
1
Single-tenant isolation
All signaling and media processing moved inside the customer’s own dedicated region, eliminating noisy-neighbor interference and delivering consistent performance at high call volumes.
2
Bring-Your-Own-Carrier SIP integration
Enterprise clients retained their existing carriers via BYOC SIP trunks, removing porting costs and migration friction while gaining SignalWire’s programmable call control.
3
Controlled change management
The dedicated infrastructure aligned release cycles and maintenance windows with the customer’s schedule, replacing ad-hoc updates that had previously broken call flows.
4
Second Frankfurt region for in-country residency
Added to satisfy Deutsche Telekom’s requirement that data never leave Germany, opening the door to one of Europe’s largest carrier relationships.
Recovery is automatic
Non-fatal errors trigger recovery phrases automatically. The caller may never notice. Fatal errors execute graceful shutdown with a hangup hook that captures final state for debugging.
