[asterisk-ss7] Cannot block CallerID with libss7

[enrico mario]

Hello,
I cannot block CallerID with attila's libss7. I've two crossed boxes with
the same software version and specular configuration. I had some checks with
"core show channels verbose" inside Asterisk, and with a protocol analyzer
(showing Calling Party Number with Presentation Allowed)
My setup:

[[[extensions.conf]]]
...
exten => 03312,1,Set(CALLERPRES()=prohib)
exten => 03312,n,Set(CALLERPRES(num)=prohib)
exten => 03312,n,Set(CALLERPRES(name)=prohib)
exten => 03312,n,Dial(DAHDI/g1/${EXTEN})
...

[[[chan_dahdi.conf]]]
[trunkgroups]

[channels]
echocancel=yes
echotraining=no
context = default
signalling = ss7
ss7type = itu
ss7_called_nai=dynamic
ss7_calling_nai=dynamic
usecallerid=yes
hidecallerid=no
callerid=asreceived
group = 1
linkset = 1
pointcode = 10
adjpointcode = 9
defaultdpc = 9
...

Anyone has suggestions? Thank you!

Mario
