Never had this before. I have a site with 4 TRUE analog POTS lines, not SIP, and using 9508 sets. Using speaker phone after they dial 9 for an available line they hear a loud feedback squelch until the call is answered.

This is happening on all 9508 sets. Could it be the card module? This is a new installation from Cox so the modem is new but they did have to come out because the first modem they installed did not work.
