variable('DIALSTATUS') returns nil on some situations

Hi Jay,

I place a call by dial(...)

Almost everything is OK with last_dial_status, except the situation, when caller cancels the call during ringing. In this case last_dial_status should return :cancelled

but it returns with error

undefined method `downcase' for nil:NilClass

Well, I tracked down that actually variable('DIALSTATUS') returns nil, which was caused by empty string returned by Asterisk

For the moment I use next workaround:

if variable('DIALSTATUS').nil?

dialstat = :cancelled

else

dialstat = last_dial_status

end
