## Channels

Each number has three independent toggles:

| Toggle        | What it enables                                                                                   |
| ------------- | ------------------------------------------------------------------------------------------------- |
| **SMS**       | Inbound and outbound text messaging. Incoming SMS lands in your [inbox](/user-guide/email/inbox). |
| **Voice**     | Inbound and outbound voice calls, governed by the voice mode below.                               |
| **Voicemail** | Unanswered calls fall through to voicemail.                                                       |

Leave channels off that you don't intend to use.

## Voice modes

When **Voice** is on, choose how calls are handled:

| Mode       | Behavior                                                        |
| ---------- | --------------------------------------------------------------- |
| **WebRTC** | Calls ring into the Bizzy web app for you to answer in-browser  |
| **IVR**    | An automated menu routes callers before (or instead of) a human |

Additional modes may appear in the UI depending on what's rolled out for your
account.

## Recording

If recording is enabled on the number, both inbound and outbound calls are
recorded. Recordings are retained per your account's retention settings — see
[Admin Guide → Billing](/admin-guide/billing/index) for storage implications.

<Warning>
  Call recording laws vary by jurisdiction. In some regions you must notify or
  obtain consent from both parties. Check local requirements before enabling
  recording.
</Warning>

## Emergency address (E911)

US local numbers must register an E911 emergency address before they can place
outbound calls — open the number's **Emergency** tab to add and validate one.
See [E911 Emergency Addresses](/admin-guide/compliance/e911) for the full
registration flow, statuses, and troubleshooting.

## Name and display

The **Name** field is how the number appears in the Bizzy UI — it's internal
only. Outbound caller ID is set by Telnyx at the provider level.

## Removing a phone number

Phone number removal releases the number back to Telnyx (or disconnects it if
it's a BYO number). Contact support if you need to remove a number — the current
UI does not expose self-serve deletion.
