[Freeswitch-users] return to shell only when call from originate is complete?

Try https://github.com/sjthomason/PyESL - pure python implementation using
the same API as the official one.

I'd generate the UUID yourself and set origination_uuid in the dialstring,
which means you can subscribe to events on that call before the
origination. CHANNEL_HANGUP and CHANNEL_DESTROY might be good ones to watch
for to know when it's complete.
