BYOC (Bring Your Own Carrier)

Connect your existing PSTN carrier to Twilio’s programmable platform and keep using your numbers while leveraging Connect features.

Twilio overview: BYOC docs
Typical use: keep current carrier contracts/coverage while using Twilio/Connect for call control, recording, and analytics.

Trunk routing: priorities and weights

When you add multiple origination targets (SIP URIs) to a Twilio BYOC trunk:

Priority: lower numbers are tried first (1 before 2). Acts as failover order.
Weight: used only among targets with the same priority. Distributes calls proportionally (e.g., weights 70/30 send ~70% / 30% of calls).

Use priorities for resilience; use weights for load-balancing peers at the same priority.
