# Vobiz Docs Sitemap - API Reference: SIP Trunking

> Every page in the API Reference: SIP Trunking section of the Vobiz documentation, grouped as it appears in the sidebar, with a one line summary of each.

Every page in the **API Reference: SIP Trunking** section of the Vobiz documentation (28 pages), grouped as it appears in the sidebar, with a one line summary of each. The other sections are listed on the [documentation sitemap](https://www.vobiz.ai/docs/resources/sitemap).

## Trunks

* [Vobiz SIP Trunking API](https://www.vobiz.ai/docs/trunks.md) — Create and manage elastic SIP trunks on Vobiz - auto-provisioned SIP domains, IP or credential auth, CPS throttling, and priority failover routing
* [The Trunk Object](https://www.vobiz.ai/docs/trunks/trunk-object.md) — Explore the Vobiz SIP Trunk object schema - SIP domain, auth mode, credentials, IP ACLs, origination URIs, rate limits, and all fields returned by..
* [Create a Trunk](https://www.vobiz.ai/docs/trunks/create-trunk.md) — Provision a new Vobiz SIP trunk with concurrent-call limits, CPS caps, TLS/SRTP, credentials, IP ACLs, and origination URIs - all in a single API..
* [Retrieve a Trunk](https://www.vobiz.ai/docs/trunks/retrieve-trunk.md) — Fetch full configuration of a single Vobiz SIP trunk by ID - rate limits, auth mode, SIP domain, and attached credentials, IP ACLs, and origination..
* [Retrieve All Trunks](https://www.vobiz.ai/docs/trunks/retrieve-all-trunks.md) — Paginated list of all SIP trunks on your Vobiz account - view configurations, monitor rate limits, and manage global SIP trunking resources in one..
* [Update a Trunk](https://www.vobiz.ai/docs/trunks/update-trunk.md) — Modify an existing Vobiz SIP trunk - update name, description, concurrent-call limits, CPS caps, or webhook URL without recreating the trunk resource
* [Assign Number to Trunk](https://www.vobiz.ai/docs/trunks/assign-number.md) — Assign a phone number to a Vobiz SIP trunk so all inbound calls to that DID route through the designated trunk - supports global and India DID..
* [Unassign Number from Trunk](https://www.vobiz.ai/docs/trunks/unassign-number.md) — Remove a phone number's trunk assignment on Vobiz - the DID returns to your account inventory and inbound routing via the trunk stops immediately
* [Delete a Trunk](https://www.vobiz.ai/docs/trunks/delete-trunk.md) — Permanently delete a Vobiz SIP trunk and all associated credentials, IP ACLs, and origination URIs - this action is irreversible and stops all trunk..
* [Trunk Webhooks](https://www.vobiz.ai/docs/trunks/webhook.md) — Configure HTTP webhooks on Vobiz SIP trunks to receive real-time call events - call admitted, rejected, or ended with duration, cost, and quality..

## Credentials

* [Credentials](https://www.vobiz.ai/docs/trunks/credentials.md) — Manage SIP credentials for username and password authentication on your Vobiz trunks - create, list, rotate, and revoke credentials per trunk
* [The Credential Object](https://www.vobiz.ai/docs/trunks/credentials/credential-object.md) — Explore the Vobiz SIP Credential object schema - credential\_id, username, write-only password, enabled flag, trunk association, and ISO 8601..
* [Create Credential](https://www.vobiz.ai/docs/trunks/credentials/create-credential.md) — Add a SIP digest credential to a Vobiz trunk to authenticate softphones, IP phones, or AI voice agents - unique username required, password is..
* [Retrieve All Credentials](https://www.vobiz.ai/docs/trunks/credentials/retrieve-all-credentials.md) — Paginated list of all SIP digest credentials on your Vobiz account - audit usernames, check enabled states, and manage authentication for global SIP..
* [Update Credential](https://www.vobiz.ai/docs/trunks/credentials/update-credential.md) — Rotate the password, toggle the enabled state, or update the description of a Vobiz SIP credential without interrupting other active trunk..
* [Delete Credential](https://www.vobiz.ai/docs/trunks/credentials/delete-credential.md) — Permanently revoke a SIP digest credential from your Vobiz trunk - every device or AI agent using that username loses authentication access..

## IP Access Control List

* [IP Access Control Lists](https://www.vobiz.ai/docs/trunks/ip-acl.md) — Manage IP-based authentication for your Vobiz SIP trunks using IPv4 whitelisting - restrict trunk access to known PBX and softswitch addresses
* [The IP ACL Object](https://www.vobiz.ai/docs/trunks/ip-acl/ip-acl-object.md) — Complete field reference for the Vobiz IP ACL object - covers ip\_address, enabled flag, UUID, and ISO 8601 timestamps for SIP trunk IP allowlists
* [Create IP ACL](https://www.vobiz.ai/docs/trunks/ip-acl/create-ip-acl.md) — Add an IPv4 address to your Vobiz SIP trunk allowlist so PBX systems, SBCs, or carriers authenticate calls without SIP digest credentials - 130+..
* [Retrieve All IP ACLs](https://www.vobiz.ai/docs/trunks/ip-acl/retrieve-all-ip-acls.md) — Fetch a paginated list of all IP ACL entries on your Vobiz account to audit whitelisted IPv4 addresses, enabled states, and trunk IP auth coverage..
* [Update IP ACL](https://www.vobiz.ai/docs/trunks/ip-acl/update-ip-acl.md) — Modify a Vobiz IP ACL entry to update the whitelisted IPv4 address, toggle its enabled state, or edit the description - all with a single PUT request
* [Delete IP ACL](https://www.vobiz.ai/docs/trunks/ip-acl/delete-ip-acl.md) — Permanently remove a whitelisted IPv4 address from a Vobiz SIP trunk, revoking IP-based authentication and blocking unauthenticated calls from that..

## Origination URI

* [Origination URIs](https://www.vobiz.ai/docs/trunks/origination-uri.md) — Configure outbound SIP routing destinations on your Vobiz trunk - origination URIs control where the trunk delivers inbound traffic for termination
* [The Origination URI Object](https://www.vobiz.ai/docs/trunks/origination-uri/origination-uri-object.md) — Complete field reference for the Vobiz Origination URI object - SIP URI format, priority, weight, transport protocol, enabled flag, and ISO 8601..
* [Create Origination URI](https://www.vobiz.ai/docs/trunks/origination-uri/create-origination-uri.md) — Add a SIP destination URI to your Vobiz trunk for outbound routing - set priority and weight for load balancing and carrier failover across 130+..

* [Delete Origination URI](https://www.vobiz.ai/docs/trunks/origination-uri/delete-origination-uri.md) — Permanently remove a SIP destination URI from a Vobiz trunk, halting outbound routing to that endpoint - keep at least one active URI to avoid call..
