# Phone Numbers

Telephony is how your agents make and receive phone calls.

Before your agent can pick up or dial a phone, you need phone lines. These come from a **telephony provider** (for example, Exotel or Twilio), which supplies the phone numbers and carries the calls. You can connect a provider account you already have, or rent one or more numbers directly from Sarvam.

Open **Deploy → Phone Numbers**.

## How telephony fits together

Everything builds up from a connection:

| Building block | What it is                                                                                                      |
| -------------- | --------------------------------------------------------------------------------------------------------------- |
| **Connection** | The link between Sarvam and a telephony provider. This is what actually carries your calls. You set it up once. |
| **Number**     | A phone number that lives under a connection — the number people dial, or the one your agent dials from.        |
| **Group**      | An optional bundle of numbers you can assign together instead of one at a time.                                 |

Once you have numbers, you decide how they're used: **[Inbounds](/conversations/deploy/inbounds)** to answer incoming calls, or **[Campaigns](/conversations/deploy/campaigns)** to dial out to a list.

## Two ways to connect

#### [Bring Your Own Telephony](/conversations/deploy/telephony/bring-your-own)

Already have an Exotel, Twilio, Smartflo, Pulse, Intalk, or Vobiz account? Connect it to Sarvam and use your existing numbers.

#### [Rent from Sarvam](/conversations/deploy/telephony/rent-from-sarvam)

No provider account needed. Rent numbers directly inside Conversations, Sarvam handles the telephony for you.

Not sure which to pick? If you don't already run a telephony provider, **Rent from Sarvam** is the fastest way to get a working number. Choose **Bring Your Own** if you already have provider accounts and numbers you want to reuse.

## Guides

#### [Manage Phone Numbers](/conversations/deploy/telephony/manage-numbers)

Assign numbers to agents, reassign, or release.

#### [Groups](/conversations/deploy/telephony/groups)

Bundle numbers so calls spread across them, callers see a local number, and you can swap numbers in and out easily.
