Teltel for AI agents

TelTel provides cloud calling and SMS infrastructure, including an autodialer and contact center tools, for teams running outbound call and text campaigns. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

EVERY TELTEL CALL, ON THE RECORD
01 · USE CASES

What agents do in Teltel.

01

Look up a phone number

Check a phone number's country and carrier details before dialing it.

02

Check the account balance

Read the current account balance as a read-only check before starting a calling campaign.

03

Confirm before placing a call

Create an outbound call only after the recipient and script are confirmed, since calls can't be recalled once placed.

02 · ACTIONS

26 Teltel actions, graded by risk.

Every Teltel action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

04 · AUTH AND DATA

How Teltel connects.

Users add their Teltel api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same Teltel connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Teltel and Arc0, answered.

Q01

Can I use Teltel with Claude, ChatGPT or Cursor?

Yes. Connect Teltel to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Teltel actions you allow.

Q02

How do users connect Teltel?

Users add their Teltel api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which Teltel actions can my agent take?

26 in total: 17 read, 7 write and 2 destructive, such as “create Call”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Teltel?

Yes. Actions like “delete User Status” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Teltel too?

Yes. The same Teltel connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
