Migrating your communications infrastructure from another CPaaS platform to Twilio requires porting numbers, rebuilding integrations, and running parallel environments long enough to validate the new setup before cutting over. Done incorrectly, a migration causes downtime, lost calls, and message delivery gaps that are difficult to recover from. Our Twilio migration service handles the complete technical transfer from Vonage, Plivo, Telnyx, Bandwidth, or any other provider with zero downtime as the deliverable.
What's Included
Phone number port-in coordination, webhook and API endpoint rebuild in Twilio's environment, A2P 10DLC or toll-free re-registration on Twilio where required, parallel testing on a staging Twilio account before cutover, cutover coordination during low-traffic windows, and 30 days of post-migration monitoring are all included. We also document every difference between your previous platform's behavior and Twilio's so your development team knows exactly what changed and what to test.
How It Works
We start with a full inventory of your existing CPaaS configuration, every number, every webhook endpoint, every messaging service, every voice routing rule. We then rebuild this configuration in Twilio, adapting for platform-specific differences in API design and webhook payload format. Numbers are ported only after the Twilio configuration has been tested and confirmed working on staging. The cutover itself is a webhook or DNS switch, not a rebuild, so it takes minutes rather than hours.
Who This Is For
Businesses that chose a CPaaS platform early and have outgrown its feature set or support quality, teams experiencing persistent deliverability problems on their current platform that the provider has been unable to resolve, companies that need Twilio-specific products like Flex, Verify, or Studio that are not available on their current provider, and organizations consolidating their communications stack onto a single vendor are all candidates for migration.
Why Choose Telphi
CPaaS migrations have a predictable set of failure points: number port timing mismatches, webhook payload format differences between platforms, and campaign re-registration delays that cause delivery gaps. We have run migrations from seven different CPaaS platforms to Twilio and know where each one diverges from Twilio's model. Our clients have not lost a single call or message during the migration period on any engagement we have managed.
Conclusion
If you are ready to move to Twilio or evaluating whether it is the right decision for your business, start with an honest technical assessment of what your migration actually involves. Book a free consultation with our team and we will map the migration scope before you commit to anything.
