---------------------------------------------------------------------- 
under: based on the time frame for 1.6.2.x support, we will never see a
version of 1.6.2 in maintenance mode past 1.6.2.15.

Since 1.6.0.x is no longer in maintenance mode, then if you post a patch
we can move this forward possibly by at least determining if the same issue
is present in 1.6.2.

Beyond that, debugging will be done against Asterisk 1.6.2.x
