Seems to work here, as long as the attribute is of type "octets".
This test file:

bjorn at obelix:/usr/local/test$ cat testfiles/3
User-Name = ppp1 at example.com
Password = b
NAS-Port-Type = xDSL
Calling-Station-Id =\000
MS-CHAP-Challenge = 0x00

results in:

bjorn at obelix:/usr/local/test$ bin/radclient -x localhost:1812 auth testing123 -f testfiles/3
Sending Access-Request of id 178 to 127.0.0.1 port 1812
        User-Name = "ppp1 at example.com"
        Password = "b"
        NAS-Port-Type = xDSL
        Calling-Station-Id = ""
        MS-CHAP-Challenge = 0x00
rad_recv: Access-Reject packet from host 127.0.0.1 port 1812, id=178, length=20

Received on the server as:

Packet-Type = Access-Request

        User-Name = "ppp1 at example.com"
        User-Password = "b"
        NAS-Port-Type = xDSL
        MS-CHAP-Challenge = 0x00
        NAS-IP-Address = 127.0.0.1
        Stripped-User-Name = "ppp1"
        Realm = "example.com"


Calling-Station-Id is a FreeRADIUS "string", not to be confused with
a RFC2865 "string".  MS-CHAP-Challenge is a FreeRADIUS "octets" type.
