SMS node is used to send an one way SMS from the current agent number to the user’s number. It only works in phone call.
This node only works for phone number that has SMS enabled. Currently only Retell Twilio number can enable SMS. Read more about enabling SMS.
The SMS will be sent when entering this node. The agent would not speak when in this node.

​
Configure SMS content

You can write a prompt to let the agent infer the SMS content, or use static SMS content. Dynamic variable is supported for static SMS content.

​
How to tell user you’re sending an SMS

Sometimes you might want to inform the user on the phone call that you’re sending an SMS. You can connect a conversation node (with skip response turned on) prior to the SMS node to achieve that.

​
When Can Transition Happen

The node would transition to the next node once the SMS is successfully sent or failed to send. It should take less than 2 seconds to get that result. It will transition out of the node purely based on the SMS result.
