Hello all,
Today I rewired my GPO 300 Mark 1 to the BT fitting. I can dial out ok but when I put down the hand set it doesn’t hang up. It just plays the dial tone quieter. Any ideas what may be causing this? I’ve checked the contacts and they are broken when the receiver is down.
Any help is very much appreciated!
