Verifone P400 -goes offline constantly
My credit card terminal keeps freezing up and I have to unplug it constantly to reboot it which takes several minutes which is an eternity when you have a line of customers. Nobody seems to understand this product. I am supposed to have ports 443 and 4443 open (was anyone else told this during their installation? I wasn't and AT&T cannot get the job done either.) Is it necessary to have a private VPN for the credit card terminal, or is there a workaround getting those impossible ports open? Anyone else having issues with their terminal going offline or do you all have enough money to support an IT manager?
