I understand, I was just saying that in some scenarios it could happen where caller A rings the MC keys and rolls to the AA, and while there a second call rings the MC keys. If the personnel are able to, they could answer the second call prior to the first caller returning from the AA for round two. Total side issue, I know.
In general the COS involved in a call with the shortest CFNA timer wins. I don't think there is a 'master' DN. What version is this?
