I have a 3825 router with 2 4-port FXO cards that has been in use for a couple of years now. Recently, we have been unable to make calls through the PSTN lines connected to those ports except we restart the router. After an extended period of use, the problem comes again and we then have to restart the router yet again. This has sort of turned into a daily affair and I know this definately isn't normal.
Below is the show ver output:

I'm lost as to what to do and would appreciate any form of guidance to identify where the problem may be as i dont want to have to replace the cards and then find out that the card was never really the problem.
Thanks in advance.
