> There is a bug in app_meetme where pbx_builtin_setvar_helper is used to set a status variable for a channel.
> However, the SLA applications also use the meetme functions, which means that when these are used, chan is NULL and thus global variables are set, erroneously polluting the global variable namespace with nonsense.
> This fixes this by ensuring that these status variables are set only if a channel exists.
