goldstar GSX 408/816 configuration

[goldstar408]

hi everyone. i have recently fitted a goldstar 408/816 system, and i am having trouble configuring the unit so the CLI (caller line ID) and call waiting works. i am currently using BT feature lines so if anyone can help me on this i would really appreciate it. on normal standard handsets CLI works but with the goldstar unit and handsets CLI and call waiting does not work.
if there is no way CLI and call waiting can work with goldstar what are alternate solution .
thanks in advance

I think CLI became common after the GSX was brought to market.

You may be struggling to get it working on that PABX.

An alternate solution would be to get an LDK or at least a PABX made this century
