Upgrade your existing Talkswitch 24-CA to a Talkswitch 48-NLS!

This kit is NOT the for older Talkswitch 24, that is a different kit. This kit is easy to install if you can use a screwdriver. A new case is included as there are more holes in the Talkswitch 48-CA case since it has more incoming and outgoing lines. You simply unscrew the board inside from the old case, screw it back into the new case, and plug the new board on top of the old board. You now have a real Talkswitch 48-CA. The settings for the original 2 lines in, and 4 local extensions remain unchanged!
