[asterisk-users] Block Collect Calls on ISDN trunk

[Rafael dos Santos Saraiva]

Richard


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()

Att,
Rafael Saraiva
