[asterisk-users] Why is this happening?

I understand all this.  However, here is my question.

MY on 4569  OTHER SIDE 1027.

Is both the incoming and outgoing traffic on OTHER SIDE going in and
out of 1027?  I understand IAX uses only one port.   I guess the down
side to this would be that MY couldn't contact OTHER SIDE if OTHER
SIDE dropped off, because it isn't working on standard port 5649.
Correct?
