[Freeswitch-users] session.recordFile issue when used right after "phrase" application

[Anthony Minessale]

You also could probably do session.execute("sleep", "2000");
But a beep is a more logical indication of when you can start recording.

I would not avoid phrase macros, they were designed to make ivr more
flexible and easy to design.
I think the problem is not related to performance it's a temporal issue so
the beep buys time for a lead-in on the recording.

The XML from the phrases are stored in memory and parsing them does not
become a bottleneck until about the 500 calls per second mark.
