Hello, I've just installed Attendent Console and am testing. Pilot point 5705 with mbrs ac1-line1, ac1-line2. 1st call to 5705 goes to ac1-line1. 1st call busy, 2nd call goes to ac1-line2. This is all good so far. If those 2 callers are still on line, the next call is busy. Both lines are allowed multiple calls per line. Any ideas??
