A:AnswerToo complicated to write here. The directions came with the phone. If you don't have access to the directions, look them up online on Vtechs website.
A:AnswerNot to my knowledge to both questions. There is no port. Need to use speakerphone button. The newer model audio ringer and dialing out sounds distorted or it could be comcast poor service. Battery life quality has gone down from my old vtech and it did annouce who was calling which this one justs beeps. Older ipads have jacks.
A:AnswerRubald - The VTech CS5129-26 does not have Caller ID announce feature. You may check the model LS6425-3 and IS8151-3 that has the feature you are looking for. Thank you! - VTech Support
