# 13246: Dial: SIP dialing not enabled for this account

Log Level: WARNING

## Description

You receive this warning when you try to send a call to a SIP endpoint from an account that is not enabled for SIP dialing. SIP dialing is used when you route a call with `<Dial><Sip>` or when you create a call with a SIP URI in the `To` parameter of the Calls API.

### Possible causes

* Your TwiML uses `<Dial><Sip>` to connect a call to a SIP endpoint, but the account that executed the TwiML is not enabled for SIP dialing.
* Your Calls API request uses a SIP URI such as `sip:user@example.com` in the `To` parameter, but the account that sent the request is not enabled for SIP dialing.
* The account that originates the SIP session does not have SIP dialing enabled. Twilio returns this warning at the account level before it can place the SIP call.

### Possible solutions

* Enable SIP dialing on the account that originates the call before you use `<Dial><Sip>` or a SIP URI in `To`. If you need help with account access or feature enablement, contact Support from the affected account.
* Use the correct SIP dialing entry point for your workflow. Route an active call with `<Dial><Sip>`, or create a new outbound SIP call by sending a SIP URI in the `To` parameter of the Calls API.
* After SIP dialing is enabled, allow Twilio SIP signaling IP addresses and media ports in your communications infrastructure so Twilio can send SIP traffic to your endpoint.
