Re: "utran-cell-id-3gpp" parameter not appended in P-Access-Network-Info header

Hello-

The bad header you're seeing:

                  P-Access-Network-Info: ; 3GPP-UTRAN-TDD

is coming when SipUnit calls javax.sip.header.HeaderFactory.createHeader(
                    header_name.trim(), value.trim());
where header_name = "P-Access-Network-Info" and value = "3GPP-UTRAN-TDD; 
utran-cell-id-3gpp=208021D0F1234567".

Apologies to the NIST LIST but I haven't been keeping up with IMS header 
discussions. Is this the wrong way to get the header in this case (IMS 
header), when given a string that could by any kind of header? (IMS or 
non-IMS)

(Note, if SipUnit is doing the right thing, inside createHeader is this 
snippet
            StringMsgParser smp = new StringMsgParser();
            SIPHeader sipHeader = smp.parseSIPHeader(hdrString);
            if (sipHeader instanceof SIPHeaderList)
            {
            }
  and the instance check is returning false in the problem scenario - is 
it correct? This is as far as I looked.)

Thanks for any help,
Becky
