CLASS modem Card on A Law

[lexer]

Hi

I'm installing a CLASS modem Card on a 11c rls 25.40 PBX, I want to CLID on analog CLASS phones. The PBX has A-Law configured, The CLID doesn't work for A-Law, If I change the PBX for working in µ-Law the CLID works.
Does Anybody has a 11c PBX with CLASS modem Card working in A-Law?
I dont know If I'm missing something

I just set the following:
Ld 13 (create cmod ports)

Set CLS CNUA and CNAA for analog phones

In Australia with FALC cards?

Thanks for answer worldwidedialtone.

I'm in south America and the PBX has to be set up in A-Law. I'm using Anlg M/WLC cards
