we intend to use the named phones as public phones in callshops, i.e. as public "telephone boothes". The phones are good for this, because we can send accounting information on the display during the call.
But we do NOT want the call duration to be displayed. There is no law that forces us to do this and the shop owners don't want it, because the end customer is making longer calls without it, so spending more money on it.
Is there a way, a switch, that displaying the running call duration can be switched off? If not, this would be a really good, better said necessary, feature to have for us!
With kind regards,
