having centrex service may be the gotcha. as stated, the real telcos offered some solutions; ground start trunks, multi line hunt groups with no secondary directory numbers or even pri will reduce the number of hang up calls your receptionist gets. but not all communication systems can accommodate either. if i understand correctly, it is the actual directory numbers associated with lines two through x that are receiving multiple robo calls. i have often wondered, if robo calls were answered and received an sf tone before an auto attendant option transfer to live attendant, would it reduce the amount of automated telemarketing calls, but loop start service as centrex complicates early call disconnect service.on the other hand loop start is required for caller id service .
