I installed a 408 board with Caller ID on an R6 V10 Legend. Caller ID will not display; I was on a joint visit w/ the carrier so I know it works at the block according to their equipment. I went into lines/trunks to change the delay and when I try and input the trunk number I get waveoff. I know the trunk numbers are right. Any suggestions? When you call, the display says 'no caller ID.' Thanks in advance.
