Is the extension in a station group?

Example: I had a station group set up with five members in sequential order. The first member is the receptionist and she wants to be able to get a second call notification on her call 2 button so she can have a chance to answer a second call also. The only way to do this is to create a station group with only her in it. Then overflow that group to another group with the rest of the extensions in it.
With Camp On active and the station groups set up this way. She now gets a second call notification. I know, strange arrangement for seemingly a simple request. I would have thought simply having a second call button would have told the system that she can except more then one call.
