Programmable Voice

BYOC Trunking for Programmable Voice is now Generally Available GA

Twilio Bring Your Own Carrier (BYOC) Trunking for Programmable Voice is now Generally Available.  BYOC Trunking is a distinct new offering that allows you to use your existing PSTN Voice Carrier partner(s), keep your phone numbers with that Carrier, and add Twilio Programmable Voice capabilities at your own pace.


  • Add programmability to your existing Phone Numbers by redirecting incoming calls delivered by your PSTN Carrier to Twilio (Termination).  
  • Send outgoing calls directly to your PSTN Carrier, including redundancy and load-balancing across multiple SIP destinations, and use Twilio’s Super Network as a fallback (Origination).  
  • No porting is necessary.
