Hi,

Is there any way to provide optional parameters like RedirectionNumber at
ACM and ANM messages?

I do the following:

${module}^sig$=;message-oprefix=osig.
${module}^sig$=;osig.BackwardCallIndicators=charge,called-free,called-ordina
ry,isup-path,isdn-end,echodev
${module}^sig$=;osig.RedirectionNumber=79859675977
${module}^sig$=tone/milliwatt;

As a result I see the following ACM

ISDN User Part
    CIC: 1
    Message type: Address complete (6)
    Backward Call Indicators: 0x0
        Mandatory Parameter: 17 (Backward call indicators)
        .... ..00 .... .... = Charge indicator: No indication (0x0000)
        .... 00.. .... .... = Called party's status indicator: No indication
(0x0000)
        ..00 .... .... .... = Called party's category indicator: No
indication (0x0000)
        00.. .... .... .... = End-to-end method indicator: No End-to-end
method available (only link-by-link method available) (0x0000)
        .... .... .... ...0 = Interworking indicator: no interworking
encountered (No.7 signalling all the way)
        .... .... .... ..0. = End-to-end information indicator: no
end-to-end information available
        .... .... .... .0.. = ISDN user part indicator: ISDN user part not
used all the way
        .... .... .... 0... = Holding indicator: holding not requested
        .... .... ...0 .... = ISDN access indicator: terminating access
non-ISDN
        .... .... ..0. .... = Echo Control Device Indicator: Echo control
device not included
        .... .... 00.. .... = SCCP method indicator: No indication (0x0000)
    No optional parameter present (Pointer: 0)

And the following ANM

ISDN User Part
    CIC: 1
    Message type: Answer (9)
    No optional parameter present (Pointer: 0)

I'm using latest SVN R3387.
