[Freeswitch-users] is loopback really 'evil'?

[Michael Collins]

Always ask this question: WHY do you need loopback? What does loopback give
you that you can't get elsewhere?
For example, in the default dialplan we use loopback for voicemail so that
people can do an attended transfer to send a call into the target's
voicemail.

My recommendation is this: if you are tempted to use loopback but aren't
sure if it's the only way to accomplish what you want, then ask here or on
IRC. In many cases you can use loopback w/o any drama. However, some people
abuse loopback by doing crazy things that Tony never dreamed of when he
created mod_loopback. That's the primary reason that loopback is "evil."

So... ask away!
