I would put a Verbose statement after Proceeding to verify the value returned
from ISDN channel, like this:
- Same => n,Verbose(RC value ${CHANNEL(reversecharge)})

Did you set CHANNEL(reversecharge) somewhere?

I tried this, but it did not work. What can be the problem?
[PABX]
exten => _x.,1,Proceeding()
same => n,GotoIf($["${CHANNEL(reversecharge)}" ="-1"]?allow:block)
same => n(allow),Dial(SIP/1584,30,tT))
same => n(block),Hangup()

exten => 100,1,Proceeding()
same => n,GotoIf($["${CHANNEL(reversecharge)}" = "-1"]?allow:block)
same => n(allow),Dial()
same => n(block),Hangup()
Please note that CHANNEL(reversecharge) is only valid on ISDN channels.
