I tried quickly with a rtpengine that was not running, and kamailio
started fine and then was responding fast for sip requests.
To clarify: you actually have more rtpengine configured (at least two)
in a set and one is not available, right?
Is the CPU usage very high? Because it is strange that is responding,
but with long delay ...
Cheers,
Daniel
