Environment

Twilio Console

User Account Permission/Role(s) Required

Your role must include permission to read SIP trunks to open the page, and permission to update SIP trunks to save changes.

Procedure

1. In the Twilio Console, select Communications.
2. Select Elastic SIP Trunking.
3. On the SIP trunks tab, select the trunk you want to configure, then open the Origination tab.
4. Under Origination settings, complete the fields:
   1. Disaster recovery URL: Twilio sends inbound calls to this URL when your origination URIs are unreachable. Optional, up to 1024 characters.
   2. Disaster recovery HTTP method: POST or GET.
   3. Header manipulation policy:choose a policy to apply to inbound calls on this trunk, or None. Optional.
5. Select Save settings.
6. An Origination settings updated. confirmation appears.

Additional Information

• Choosing None detaches any policy currently applied to the trunk's inbound calls.
• The policy list is drawn from the SIP header manipulations tab, so create a policy there first if the list is empty.
• The disaster recovery URL is a safety net, not a substitute for origination URIs. Configure at least one origination URI in the Origination URIs section on the same tab.
