Hello People I bought a new corded phone with caller ID recently to replace the old one. The new phone has considerably more humming than the old one. Q1. Is there any config I should do to the PAP2T? Or too bad I have bought an "unsuitable phone"? Q2. If there really are such things as "unsuitable phones" for PAP2T, which are the 'suitable phones"? Q3. If this question has been discussed before, please guide me to it.
