By filter, do you mean the one that goes to the phone line to the phone?

If so, you might want to check that it is going to the PHONE and in the right direction.

Also, it would GREATLY help if you explained how/if the phone is working. You did not make it clear as to whether that even worked, but as of now, i would assume the phone is working fine, as you did not mention it.
