What integer values are in response_timeout and interdigit_timeout? Just curious, because if they are too large then it will indeed block while waiting for events.

I have this code below in which I want to receive and extract dtmf events.
It seems all previous events are queued and received together at this point as the while loop is run. I don't know why it does this I only need the current events to be received.

Another issue happening at this point when I press any digit 0-9 on the phone it is not getting an incoming dtmf events



while @con.connected
    #debug   
    puts "start loop"
   
    #no digits
    if dtmfbuffer.length == 0
        e = @con.recvEventTimed(response_timeout)
    # there are digits
    elsif dtmfbuffer.length > 0
        e = @con.recvEventTimed(interdigit_timeout)
    end


    if e
        name = e.getHeader("Event-Name")
        puts "#{name}"
        break if name == "SERVER_DISCONNECTED"
        if name == "DTMF"
            digit = e.getHeader("DTMF-Digit")
            duration = e.getHeader("DTMF-Duration")       
            dtmfbuffer << digit
            puts "*** Dtmf #{digit} dur:#{duration} from #{@cli}"
        end
    end

    if dtmfbuffer.length > 9
        break
    end
        #debug
        puts "end loop"
end
