I have a phone number in Iceland that some people here can call and others get a fast busy. Tried this number from different phone types and the only difference that I can see is the bcc field on my station is different than the others. I can get through. I know if anyone picks up a phone with the same COR it should behave the exact same way, but it's not. I'm baffled. any ideas and if this bcc field means anything on the station level. I can't change the value of it either.
