Rent from Sarvam | Sarvam API Docs

Rent from Sarvam lets you provision phone numbers directly within Voice Agents, without an external telephony provider account, credentials, or provider-side configuration. Sarvam manages the underlying telephony for you through its native Vobiz integration.

FAQ

How much do these phone numbers cost?

Pricing depends on the number. Different numbers have different pricing, which you’ll see in the catalog on the UI when you browse available numbers.

What is the minimum duration I can purchase this for?

Numbers are rented for 30 calendar days. After that, the rental auto-renews unless you cancel it.

Do I need to add a credit card to purchase this?

No. The cost of the number is deducted from your Sarvam wallet.

I already have phone numbers in my Vobiz account. Can I use those?

Yes, but not through Rent from Sarvam. If you already have an existing Vobiz account, connect it as Bring Your Own Telephony instead.
