20 Most Recent Vtech IA5854 5.8 GHz Cordless Phone Questions & Answers

A guess - Some phones have a conference, room monitor or intercom feature. Make sure all intercom use is off on each handset as well.

first of all using magic jack compared to a hardwired is complete nonsense, in an electrical storm if your building is hit it fries the magic jack gear, and you cannot dial 911, secondly, there is no battery back-up compared to dc fed phone lines!

Sounds like you have a defective microphone in your handset. Maybe caused by dropping of phone or water damage. Try land line phone not cordless. Just to ensure that you can hear the caller and can be heard over your phone line.

If you can complete a call successfully go and purchase another cordless phone.

Sorry, you can't. Your new headset uses the DECT 6.0 protocol where your old 5.8GHz headset uses a different protocol. It would be like trying to play a videotape on a DVD player.

Since the IA5854 isn't a DECT 6.0 system, you're obviously asking about another model. Enter the model into the search box at http://www.vtechphones.com/support/general/manuals to download a copy of the manual.

This phone doesn't give you a way to change the ringer volume. However page 9 of this manual describes how to change the ringer style.
