Zero downtime.
Zero dropped calls.
Switching telecom carriers is terrifying for most IT teams. We built a side-by-side migration protocol that completely eliminates the risk of an outage.
Plan your migrationSide-by-Side Testing
We provision your UnlimCall SIP endpoints. You configure them inside your dialer (e.g. ViciDial) alongside your existing carrier. You route just 5% of your outbound traffic through us to verify latency and connect rates in real-time, without touching your main production flow.
Number Porting (LNP)
Once you are satisfied with the audio quality, our compliance team initiates Local Number Portability (LNP) requests for your existing Caller IDs. Your old carrier is legally required to release them. We handle the paperwork.
The Cutover
With numbers ported and STIR/SHAKEN certificates applied, you update your dialer's dialplan to send 100% of traffic through UnlimCall. You can now safely cancel your legacy carrier contract.
