Summary:                    [patch] Zaptel/DAHDI channel name don't change after
a hookflash event
Description: 
During a conversation using Zaptel/DAHDI channels, pressing flash on
Zap/1-1 creates a new channel named Zap/1-1 instead of Zap/1-2 like
previous asterisk versions, so there are 2 active channels with same name.
Looking further in SVN tree, seems that this is broken since Asterisk
1.4.5. exactly is broken between releases 66312 and 66602 when changed
function asprintf to ast_safe_string_alloc inside func zt_new. It compares
channel names 'Zap/1-1' with content of var 'b2' that has the remaining
part of the string, '1-1' instead of the full channel name string.
(see diff
http://svn.digium.com/view/asterisk/tags/1.4.5/channels/chan_zap.c?r1=66312&r2=66602
or attached svn diff)
I don't think that is a new convention for names, seems like a bug to me
introduced when wanted to correct http://bugs.digium.com/view.php?id=9825.
