just to clearify
although i dont recomend useing $chan and such in aliases, but rather simply sending the proper parms to them, you CAN use them in aliases provided that the aliases are called by an event :P
and even in timers in aliases that are called by an event where $chan will resolve as the $chan identifer will resolve before the timer is set .. although in this case, the alias was not called by an event so obviously $chan would be $null
