ATA 186 with Billing machine

How should I connect ATA 186 with PCO Billing Machine, so that the calls are automatically registered and billed.

Re: ATA 186 with Billing machine

You might have seen the billing machine giving the printouts immidiately after the call terminates. The system goes like this...From my ATA box both the lines goes to Billing machine and then from billing machine I connect my telephone instruments. Problem is ...I have to press the activation button manually...which I want to be automatically taken. For this I have to Reverse Polarity on these 2 lines which can be configured on my ATA. Now how to Reverse the polarity and what will be the values ??
