I have a Panoramic router with a Panasonic wireless phone system connected to it. Sometimes, when the phone rings and I answer, I can't hear anyone and they can't hear me. It does it just a couple of times a day but can be frustrating to both parties. I upgrated the router, no help. Switched to different phone manufacturer, no help. Unplugged the printer which is on wifi to see if the printer was trying to use fax line, no help. I've run out of ideas.
Any problems with the internet at the time of the issue with the phone? Also, does it happen with outgoing calls too?
No internet issues. Does not happen with outgoing calls.
That rules a lot out. How do you have the phone wiring set up out of the back of the phone modem/router? Do you have it going direct into a phone or into a phone jack? Does the jack use a line splitter?
