asterisk users - Apr 2008 - AEL: how to copy a variable without interpretation of the content

I've got the next AEL:

       TEST=${X-CALLID};
       NoOp(${TEST});

where X-CALLID=ctprueba-1208953210.12 (passed by a custom sip header)  

Executing I've got the error:

[2008-04-23 13:24:01] WARNING[15638]: ast_expr2.y:742 op_minus: non-numeric
argument
    -- Executing [1009 at fromsip:8] Set("SIP/172.16.4.6-b6c06688",
"TEST=0") in new stack
    -- Executing [1009 at fromsip:9] NoOp("SIP/172.16.4.6-b6c06688",
"0") in new stack
 

So my problem is how to copy the X-CALLID variable with no interpretation of the
content?


Thanks
Eric Dantie

X_CALLID=SIP_HEADER(X-CALLID);
NoOp(${X_CALLID});

Strangely, working...
TEST should be "ctprueba-123456789.12"  but not ctprueba-123456789.12
But got the value.

Thanks.
