CLIP on Analog

So. I am trying to set CLIP on an Analog user. The PABX accepts the command, but then the phone does not ring!
I have put a scope on it, and the PABX is not sending ringing voltage anymore. But the call is placed correctly (when you go off hook, the call completes). When I take off the CLIP option, the phone works as normal.
This problem occurs on more than one Z24_2 board on different shelves. My Alcatel is running OXE Rls 11.1

Any suggestions would be gladly received :)

I think you need a daughter board for the CLIP. Do all your boards have it ?
From the documentation:

Three daughterboards are available:
• The CLIDSP board is used to detect tones and to assign its own DSPs to CLIP detection (see the CLIP on analog trunk group - Overview).

• The METCLI board is used to implement:
• Metering (12kHz or 16kHz detection)
• Detection of the polarity when idle
• Detection of CLIP impedance (required in certain countries in order to implement the CLIP
function)

• The GSCLI board is used to implement:
• The Ground Start protocol (USA)
• Detection of the polarity when idle
• Detection of CLIP impedance (required in certain countries in order to implement CLIP)
The APA4 board does not permit both daughterboards (METCLI and GSCLI) to be connected, as there is only one dedicated slot available. The APA8 board, however, allows both daughterboards to be connected (METCLI on interfaces 1 to 4 and GSCLI on interfaces 5 to 8, or vice versa).

i think, for internal analog users clip is possible only on z32 or ez32 boards.
