security on phone

Hello @user_26n1a7 Thank you for taking your time to create this post here in Forums. What a great question! It depends on what you mean by phone, if you are referring to our landline. For added security on a landline, Xfinity offers features such as Caller ID, Caller ID Blocking per call/line, and Anonymous Call Rejection. These features help manage incoming calls and protect against unwanted or spam call.  You can also check out https://www.xfinity.com/support/articles/voice-callplan-overview For our mobile devices, we do have some call blocking and reporting features as well. Could you tell me which service? All around! Security and privacy are very important to us! And we like to included different options for all of our services.
