is there a way to pause the execution of a dialplan?  The sleep and answer_delay commands only pause the media but the rest of the dialplan still executes right away.

The use case I have is this:

1. Dial FS from a WebRTC client.

2. Answer the call to start the handshake

3. Sleep for 2.5 sec to handle the handshake delay.

4. After that make a curl call to tell another system that the call is connected.
