[Freeswitch-users] Pausing dialplan execution

Guys, 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.
