Post Dial Delay - the time between the call starts (an INVITE) and there's a progress indication (a 183 or early media).
You can find the delay time set as a channel variable:
In Seconds:
- progress_mediasec
- progresssec
In milliseconds (1000 = 1 second):
- progress_mediamsec if there was media
- progressmsec if there was no media
In MicroSeconds (1000 = 1 millisecond)
- progress_mediausec
- progressusec
Only one will be set, the other will be 0. PDD in seconds = (progress_mediamsec + progressmsec) / 1000
