Hi, I have two Philips DECT phones: Onis2 Memo (TD6511/BS6511) - british standard and one Onis TD6211/BB191P (BS6211) - french standard. Both of them does not show nothing as callerid connected to an ATA186 or to the PSTN line. A cheap analog cordless (GE) can get the callerid (both name and number) when is connected to the same ATA. With the X100P I have succeed make it get the correct callerid from the PSTN line. There is any french or british list member who succeed using callerid functionality on ATA186? Thanks, Dan
