Summary:                    AEL & CUT
Description: 
CUT doesn't seem to work like I would expect.

This works:

macro route-enum-2(exten, Timeout, DialOpts, dns) {
    Set(ENLCOUNT=${ENUMLOOKUP(+${exten},ALL,c,,${dns})});
    if (${ENLCOUNT} > 0 )
    {
        for(count=1;${count} <= ${ENLCOUNT};count=${count} + 1) {
            Set(ENL=${ENUMLOOKUP(+${exten},ALL,,${count},${dns})});
            if (${LEN(${ENL})} > 0) {
                if ("${ENL:0:3}" = "sip") {
                    Dial(SIP/${ENL:4},${Timeout},o${DialOpts});
                } else if ("${ENL:0:4}" = "iax2") {
                    Dial(IAX2/${ENL:5},${Timeout},o${DialOpts});
                } else if ("${ENL:0:4}" = "h323") {
                    Dial(H323/${ENL:5},${Timeout},o${DialOpts});
                };
            };
        };
    };
};



This doesn't work:

                switch (${CUT(ENL,:,1)}) {
                    case sip:
                        Dial(SIP/${ENL:4},${Timeout},o${DialOpts});
                        break;
                    case iax2:
                        Dial(IAX2/${ENL:5},${Timeout},o${DialOpts});
                        break;
                    case h323:
                        Dial(H323/${ENL:5},${Timeout},o${DialOpts});
                        break;
                    default:
                        NoOp(blah);
                };

Hmm.

NoOp(the result of cut is '${x291}'...)  gives  "sip", as expected.

Then this works:
Set(x291=${CUT(ENL,:,1)});
switch (${x291}) {
    case sip:
        ...


But this doesn't:
switch (${CUT(ENL,:,1)}) {
    case sip:
        ...




Here's the trace:
    -- Executing [s at macro-route-enum-2:10] NoOp("SIP/nonposter-006f7da0",

I guess I'll assign the result from CUT to a variable in my dialplan
instead of using CUT directly.  (I thought I tried this already...  lack of
sleep...)
