SX200-ICP ARS with leading digit of 3 problem

[Bellpatrick]

I have several SX200ICP's that I an adding ARS entry's for IP trunking. When I try to add a leading digit of 3 the system says it is already assigned. I can add 30, 31, 33, 34, 35, 36, 37, 38, and 39 as leading digits but not 3 or 32 or 328. if I break it down further I can add 3280 through 3289 just not 328, 32, or 3 as a leading digits. I have looked everywhere and I cant find any service codes, extension numbers or anything really that would be conflicting. anyone else ever run into this? it is happening on all three systems.

By default the 200 ICP has an ext 328 programmed as a telnet socket in form 12

You can check form 35 for devices starting with 32

If you already have access codes 3X then the system wont allow a single digit
