In traffic_shaper_wizard_multi_all.xml wizard when you get to the VoIP bandwidth screen there is a box for each WAN, and each LAN, to define VoIP bandwidths.

For example, let's say you have 2 WANs and 7 LANs.

The values are checked in a loop that doesn't appear to be matching things up right. It's looping over the number of local interfaces (in this case 7), and taking the value of conn{$i}downloadspeed (wan) and local{$i}downloadspeed (lan), when it gets to $i=2, this breaks as only WAN 0/1 exist. It gives an error about exceeding 80% but it's comparing it against a zero/null value so it's really an invalid value, not exceeding a limit.

Looks like it may be similar to the correction made in b0d088eb6fe3cf91ddd4aade1540a5749f551aa7 to one of the other wizards.
