    The round robin routing routine in chan_misdn.c is broken.
    
    it rotates between ports but never checks the channels in the ports.
    
    i have extensivly tested it and verified it works on 1 upto 4 ports.
    before the patch only 1 out of each port was used now all are used as
    expected.
    
    (closes issue ASTERISK-18413)
