Can I make an outbound call to the SIP URI of a Plivo application?

Yes, you can make an outbound call to the SIP URI of a Plivo application. For example, you can make an HTTP POST request to originate an outbound call to “sip:example@app.plivo.com” which is the SIP URL used to identify the Plivo application.

Having said that, if you’re expecting to receive calls delivered to your SIP URI, you would create a SIP endpoint that’s attached to your Plivo application in the ‘Endpoint’ tab and share them with others, not the SIP URL of your application.
