SIP Management If you are an Enterprise customer and you would like to use this feature, contact support to enable access. *** ### Citations Enhancements (Enterprise) Enterprise orgs can now: * Attach multiple citation schemas to a call * Run [citation backfills](../api-v1/post/citation-schemas-backfill) on historical calls * Add descriptions to categorical variables for better clarity These updates make it easier to manage and interpret insights from your enterprise calls. For more information, see our [Citations tutorial](../enterprise-features/citations) and [API reference](../api-v1/get/citation-schemas-list). *** ### Improvements * Fixed an issue where selecting a citation schema on the phone number UI did not include the schema ID in the post-call webhook payload. * You can now filter and search for Twilio numbers when adding or managing them in the Add-Ons page. * Fixes edge case where certain outbound calls were exceeding their preset maximum duration. * Fixes error preventing background audio from being attached to inbound phone numbers. * A new Copy Link button has been added to the Selected Call view for quickly sharing call URLs from the logs page.
