Hi Petros
If you are using the Nexer / LDK-24 version 1.0, 3.0 and 3.7 you can use the elder keysets from LG Nortel (Goldstar)
like LKD-30DS, LKD-30LD or LKD-8DS.
Today new LDK-24's are delivered in version 3.7, and this version can handle almost any 2 wired LG / Goldstar keyset.
The problem will come if you have an elder LDK-24 in version 1.0 and want to install the new keyset type: LDP-7000 (7004, 7008, 7016, 7024 and 7024 LD). All these phones need version 3.0 or 3.7 of the Nexer / LDK-24.
To see the software version of an LG LDK PBX press Trans/PGM and 72 on any keyset installed with the LG LDK PBX.
There is no solution to your problem.
If your LDK-24 is in version 1.0, only elder LG /Goldstar keysets can be used, not the LDP-7000 series!
