Asterisk - remote ringback

    This could be a long one, sorry. The question will be
    short, but right down at the bottom

    Making use of the instructions on Nerd Vittles & with
    a lot of help from chandave on Voxilla, I've setup
    Asterisk with a special Sipgate DID number.

    If either my wife or I call it on from our mobiles,
    it rings & should hang up after a couple of rings. (For
    some reason, it's not hanging up in this example but is in
    the 2nd example, though the call back works fine)

    Then, using DISA, Asterisk will wait 8 seconds and call
    me back using the trunk specified in line h,100. This happens
    to be a premicell to make use of bundled minutes. Once I
    answer, it asks me for my password & then gives me
    a dialtone. I can then ring out on any of my trunks,
    exept for the one doing the call back of course.

    Example 1

    In extensions_custom_conf:

    [custom-sipgate-in]
    exten => 1234567,1,NoOp(Incoming call from Sip #1234567); replace 1234567
    with your Sipgate DID
    exten => 1234567,2,ringing(3)
    exten => 1234567,3,Wait(5)
    exten => 1234567,4,Congestion
    exten => 1234567,5,Hangup
    exten => h,1,SetCIDNum(${CALLERIDNUM:0})
    exten => h,2,GotoIf($["x${CALLERIDNUM}x" = "xMyMobileCLIDx"]?100)
    exten => h,3,GotoIf($["x${CALLERIDNUM}x" = "xWife'sMobileCLIDx"]?100)
    exten => h,99,Goto(999)
    exten => h,100,System(echo channel: SIP/spa mobile/${CALLERIDNUM} >
    /tmp/${CALLERIDNUM});spa mobile is the name of my chosen callback trunk
    exten => h,101,System(echo context: custom-disa-callout >>
    /tmp/${CALLERIDNUM})
    exten => h,102,System(echo extension: ${CALLERIDNUM} >> /tmp/${CALLERIDNUM})
    exten => h,103,System(echo priority: 1 >> /tmp/${CALLERIDNUM})
    exten => h,104,System(echo callerid: 01234567890 >> /tmp/${CALLERIDNUM}) ;
    Your CallerID for your SIP account goes here
    exten => h,105,System(echo sleep 8 > /tmp/${CALLERIDNUM}.2)
    exten => h,106,System(echo cp /tmp/${CALLERIDNUM}
    /var/spool/asterisk/outgoing >> /tmp/${CALLERIDNUM}.2)
    exten => h,107,System(chmod 775 /tmp/${CALLERIDNUM}.2)
    exten => h,108,System(/tmp/${CALLERIDNUM}.2)
    exten => h,109,Goto(999)
    exten => h,999,Hangup()

    [custom-disa-callout]
    exten => s,1,Playback(enter_pin)
    exten => s,2,Authenticate(17599)
    exten => s,3,Background(pls-wait-connect-call)
    exten => s,4,DISA(no-password|from-internal)

    ***************************************

    edit or create & edit disa.conf (in /etc/asterisk)

    add the line

    SecureNumericPassword|outbound-allroutes ;replace SecureNumericPassword with
    numbers!

    ***************************************

    Create a DID (1234567)

    Point it to custom app, replace 1234567 with your Sipgate DID
    custom-sipgate-in,1234567,1

    =======================================

    Example 2

    In extensions_custom.conf

    [custom-landline-in]
    exten => 7654321,1,NoOp(Incoming call from Sip #7654321)
    exten => 7654321,2,ringing(3)
    exten => 7654321,3,Wait(5)
    exten => 7654321,4,Congestion
    exten => 7654321,5,Hangup
    exten => h,1,Goto(100)
    exten => h,100,SetVar(num=0044${CALLERIDNUM:1})
    exten => h,101,GotoIf($[$num :
    ^0044[1-2][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]]?:999) ; Priority
    999 should be a Hangup()
    exten => h,102,SetCIDNum($num)
    exten => h,103,System(echo channel: IAX2/sipdiscount/${CALLERIDNUM} >
    /tmp/${CALLERIDNUM})
    exten => h,104,System(echo context: custom-disa-callout >>
    /tmp/${CALLERIDNUM})
    exten => h,105,System(echo extension: ${CALLERIDNUM} >> /tmp/${CALLERIDNUM})
    exten => h,106,System(echo priority: 1 >> /tmp/${CALLERIDNUM})
    exten => h,107,System(echo callerid: 01234567890 >> /tmp/${CALLERIDNUM}) ;
    Your CallerID for your SIP account goes here
    exten => h,108,System(echo sleep 20 > /tmp/${CALLERIDNUM}.2)
    exten => h,109,System(echo cp /tmp/${CALLERIDNUM}
    /var/spool/asterisk/outgoing >> /tmp/${CALLERIDNUM}.2)
    exten => h,110,System(chmod 775 /tmp/${CALLERIDNUM}.2)
    exten => h,111,System(/tmp/${CALLERIDNUM}.2)
    exten => h,112,Goto(999)
    exten => h,999,Hangup()

    **************************************

    Create a DID (7654321)

    Point it to custom app, replace 7654321 with your Sipgate DID
    custom-landline-in,7654321,1

    **************************************

    In the above example, I'm attempting to allow a call back
    ONLY to numbers that start 01 or 02 and are 11 digits
    long - so that it can be used from any landline or payphone.

    Line h,100 strips the leading zero & prepends 0044 and
    sets this number as the variable num

    Line h,100 checks that the number (now) is in the format
    00441XXXXXXXXX or 00442XXXXXXXXX, I think. If the number
    isn't in this format, it should go to priority 999,
    which is a hang up.

    Unfortunately, the call back nevers happens. (it works great
    in example 1)

    Any experts see any errors around lines h,100 to 103 in example 2?

    you could try

    exten => h,100,SetVar(test=${CALLERIDNUM:2:1})
    exten => h,101,GotoIf($[${test} = [1-2]]?103) ; Priority 103 would be the
    continuation of the call
    exten => h,102,Goto (custom-landline-in,h,999);

    This has assumed the cli is presented in UK number format not 0044 also I
    havent tested the length but thats not hard.

    I havn't tested that it would work but it looks ok.

    Hello Ian,

    Thanks for taking the time to reply.

    I will check out your suggestion!

    Could you, by any chance explain the arguments used in:
    exten => h,101,GotoIf($[${test} = [1-2]]?103)

    Cheers.

    Havng reread it it looks wrong.

    The following should work though
    (still not tested it but it looks ok)

    exten => h,101,GotoIf( $["${CALLERIDNUM:1:1}" = "1"]?105) ; Priority 105
    would be the continuation of the call
    exten => h,102,GotoIf( $["${CALLERIDNUM:1:1}" = "2"]?105) ; Priority 105
    would be the continuation of the call
    exten => h,103,GotoIf ($[${LEN(${CALLERIDNUM})} = 11]?105) ; Priority 105
    would be the continuation of the call
    exten => h,104,Goto (custom-landline-in,h,999);

    as to what its doing 101 checks to see if the second digit is 102 checks to
    see if its 2 then 103 checks that its 11 digits long.

    That's very clever. I've been amazed at how many different ways there are of
    doing things.

    I've (only just) got it all working with the following:

    [custom-landline-in]
    exten => 7654321,1,NoOp(Incoming call from Sip #7654321)
    exten => 7654321,2,ringing(3)
    exten => 7654321,3,Wait(5)
    exten => 7654321,4,Congestion
    exten => 7654321,5,Hangup
    exten => h,1,Goto(100)
    exten => h,100,GotoIf(${CALLERIDNUM} :
    0[1-2][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]])?:999)
    exten => h,101,System(echo channel: IAX2/sipdiscount/0044${CALLERIDNUM:1} >
    /tmp/${CALLERIDNUM})
    exten => h,102,System(echo context: custom-disa-callout >>

    exten => h,103,System(echo extension: ${CALLERIDNUM} >> /tmp/${CALLERIDNUM})
    exten => h,104,System(echo priority: 1 >> /tmp/${CALLERIDNUM})
    exten => h,105,System(echo callerid: 01234567890 >> /tmp/${CALLERIDNUM})
    exten => h,106,System(echo sleep 20 > /tmp/${CALLERIDNUM}.2)
    exten => h,107,System(echo cp /tmp/${CALLERIDNUM}
    /var/spool/asterisk/outgoing >> /tmp/${CALLERIDNUM}.2)
    exten => h,108,System(chmod 775 /tmp/${CALLERIDNUM}.2)
    exten => h,109,System(/tmp/${CALLERIDNUM}.2)
    exten => h,110,Goto(999)

    I can see that you have a false destination but no true destination, Does i
    fail if you dial in with a mobile or have international CLI.? I have not
    seen Gotoif documented like this. are you sure its not just steppng through
    as i can see a clossing bracket but no opening one.

    Well spotted..........it doesn't fail on my mobile....funny, I thought it
    did - it must've failed before for some other reason. Bugger. What's
    missing?

    Well I dont know whats missing as Iv never seen this way of using the Gotoif
    command. Where is this way documented ?
    Personaly I use it like i posted earlier or comparing against entries in
    the database.
    The wiki has some good info on Gotoif its worth a read.
    For what you are trying to do I would use authenticate a that way it proves

    Thank you Ian.

    I've been in discussion with a chap on the voxilla website. He's helped me a
    great deal - I have a different call back number, as a direct result, that
    is doing exactly what I need for that application. (it authenticates by
    CLID)

    http://voxilla.com/PNphpBB2-viewtopic-t-6320-postdays-0-postorder-asc-start-0.html

    However, for this particular application, I want to be able to call from any
    (& only a) landline, then call back to the same landline, then authenticate
    by password & get a VOIP dialtone. (Actually I will then want to restrict
    calls to landlines @ the dialtone as well) I think I'm being a little dense
    & am not getting too far with the latest attempt!

    Hi Ian,

    The kindly chap on Voxilla, "chandave" just posted a reply...........and now
    it's working as a hoped it would.

    exten => h,100,GotoIf($[${CALLERIDNUM} :
    0[1-2][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]])?:999) ;999 is a hang
    up.
