I am having problems with the caller ID on my 522. It will not work at all. All my phone ID's work fine, but not the 522. I have dsl, but all the filters are in place. I just cant figure out why it works with my phones, but not the 522. I have a call into DiSH and they said that it is a known issue. Seems weird that some work and some dont though. Thanks for any help you can give.
