What messages do you want to send? Be Specific.
Like i said you CANNOT blindly  call sendmsg on any channel that was not
first parked to indicate you should be controlling it.
Also like I already said, if you open a new inbound event socket connection
and isssue "myevents <uuid>"
it is identical to as if that was an outbound event socket from the desired
channel.  It's new in latest trunk.

Probably if you explain *exactly* what you want to accomplish there is some
simple way to do it.
Don't fret about the difference between inbound and outbound there is no
difference besides you cant control calls that
were not in park.

I'll tell you what, i'll lift that restriction in latest trunk and you tell
me if it breaks anything or if it makes your life
easier since it's not really doing much but protecting you from yourself. So
with latest code you can use your one socket
to send messages to the other leg too.
