[Freeswitch-users] Inline execution concept

[Avi Marcus]

Tim, that's an excellent description. Can you please find/add/update that
on the wiki?
It would be great if most answers on this mailing list to explain something
were links to the wiki. Or even better if the wiki was so well organized
and explanatory that they wouldn't even need to ask.

-Avi
