I have the Toshiba CTX100 phone system and using auto attendant and I'm trying to turn the ringer off some of the phones that ring when a caller dials "0" for the operator. The problem that I have is I have 4 phones located in a very small area and when a caller hits "0" the 4 phones ring within .5 seconds apart so it sounds like constant ringing because they don't all start ringing at the exact same time, does that make sense?
