Phone/ASDL Secondry Socket
I have installed a secondry socket (extension from main socket) with a phone port and an ASDL port. The ASDL port is working fine but the phone will not work from the phone socket. The same phone will work from the master box and did work from the extension box until recently. I have changed the extension box but to no avail. Has anyone any idea why this should be?
Many thanks.
