[asterisk-users] Block Collect Calls on ISDN trunk

[Danny Nicholas]

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)})

This is a variable received from the isdn channel.

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.
