We have several different phone systems in our school district. Some schools are on NEC, others Toshiba DK16e, and also Toshiba CIX.

I have been successful in removing the toll restrictions on some teacher's phones (locals) on the NEC and DK16e systems (using the programming sequence from a compatible phone) but I'm unable to figure out how to remove the toll restriction on the CIX system...

Any help would be appreciated. Thanks!
