I think this is not a good idea since an inbound call could arrive
between 1) and 2) making the channel no longer available (the app isn't
named ChanIsAvailAndReserveForOutgoingCall). Use ZAP/g1 (or whatever
your group is) - works for me on PRI (both as net and as cpe) -
depending on the behaviour of the other side ZAP/G1 could reduce the
likelihood of the same channel being used by both sides.
