I would highly recommend doing a test with your provider and your PBX
to see if there are any interop issues. Also, OpenZAP has a PRI issue
where channels don't go back to DOWN (i.e. idle/on-hook) properly.
It's a known issue that is being worked on but it's being done in a
volunteer's spare time so there's no ETA on that. I would recommend
that you hop on IRC and join both #freeswitch and #openzap channels.
User Cypromis is putting some openzap stuff into production next week
so you might want to pick his brain on the issues that he sees.
