# What does the Twilio plugin support?

The Twilio plugin lets you connect Twilio SMS messaging to Crisp.

It does not support Twilio voice calling. If you need calling in Crisp, use a dedicated phone integration such as Aircall.

# Link Crisp with Twilio

* Go to [app.crisp.chat](https://app.crisp.chat)
* Go to plugins
* Click on Twilio
* Provide your Account SID and Account Token
* Choose a Phone Number

# Troubleshooting

###### I don't receive any SMS in Crisp

In this case, Crisp might fail to configure a webhook. Usually, it's because there is a conflict with a third party provider, updating the webhook in the same time.

* Connect to the Twilio Console
* Go to your Phone Numbers
* Check the webhooks
* Ensure the webhook is starting with [**https://plugins.crisp.chat/urn:crisp.im:twilio:0/**](https://plugins.crisp.chat/urn:crisp.im:twilio:0/)

![Ensure Webhook is selected in the list](https://storage.crisp.chat/users/helpdesk/website/-/6/9/a/7/69a72e90ff59f000/f003b6db-3217-44e8-be42-fe836a_1v3k1mv.png)

###### I can't reply to my users

Ensure you provided the correct ****Account SID**** and ****Account Token**** and these credentials have access your phone number.
