# BYOC (Bring Your Own Carrier)

> How to connect external PSTN carriers to Twilio and Connect, manage trunks, and compare provider options.

# 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](https://www.twilio.com/docs/voice/bring-your-own-carrier-byoc)
* 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.
