As far as I can see, the reason is that there's 2 local channels created (see local_new() in chan_local.c) but I think only one of the 2 (and not the good one) inherit _ prefixed variables (see local_call()).
Comments:	By: Kevin P. Fleming (kpfleming) 2005-11-07 20:08:41.000-0600 This is not fixable, as it is behaving 'by design'. The single _ prefix variable is being inherited into the channel created by app_dial, but that is not visible in the dialplan. It is _not_ inherited into the channel created by chan_local, because that is a second level of channel creation and single _ prefix variables only get inherited into a single level of channel creation. By: Kevin P. Fleming (kpfleming) 2005-11-08 15:48:11.000-0600 Mark has decided to change the behavior here, to make chan_local appear more like a single channel instead of its current two-channel appearance (even though it uses two channels internally). To that end, chan_local now _moves_ all the variables from the incoming channel to the outgoing one, rather than using the inheritance method. This should solve your problem.
