call_into_context doesn't accept async

def call_into_context(channel, context, options={})

        deprecation_warning
        args = {:channel => channel, :context => context}
        args[:priority] = options[:priority] || 1
        args[:extension] = options[:extension] if options[:extension]
        args[:caller_id] = options[:caller_id] if options[:caller_id]
        if options[:variables] && options[:variables].kind_of?(Hash)
          args[:variable] = options[:variables].map {|pair| pair.join('=')}.join('|')
        end
        originate args
      end

Locally I just added

        args[:async] = options[:async] if options[:async]

But I don't know the implications of doing so.
