# Admin (/docs/overview/admin)

> For the complete documentation index, see [llms.txt](https://docs.tandemcx.ai/llms.txt). Any page on this site can be fetched as Markdown by appending `.md` to its URL.

**Admin** in the left navigation covers the settings that apply to your whole organization
rather than to one workflow or one agent: who can sign in, the credentials and shared
values your workflows and agents draw on, the domains you send email from, your phone
numbers, and your balance.

The section is gated on the administrator role. Every role Tandem issues today (Owner,
Admin, and Member) carries it, so in practice everyone in your organization can open
these pages. Member is planned to become a limited role; until it does, don't rely on it
to keep someone out of Admin. See [Manage Users](/docs/overview/manage-users).

## Pages not yet documented

One Admin page has no guide in this portal yet. It works; it isn't written up here yet.

| Page              | What it does                                                   |
| ----------------- | -------------------------------------------------------------- |
| **Phone Numbers** | Buy numbers, and point each one at a workflow or a voice agent |

**SIP Trunks** connects your own carrier to Tandem over SIP. Its guide so far covers
[inbound SIP headers](/docs/overview/sip-trunks). Contact support if you need either page walked
through before its guide is written.

## Some pages are still rolling out

Email Domains, Billing, Contact Attributes, Audit Log, SIP Trunks and Sub-Tenants are enabled
per organization. If one isn't in your sidebar, it isn't switched on
for you yet. Contact support rather than assuming the page has moved.

SMS Sender Registration is also rolling out. Until it reaches your organization, a phone
number's sidebar shows its SMS status but no Enable SMS action. See [SMS Sender
Registration](/docs/overview/sms-sender-registration).
