You can use the parsing function to create the appropriate instance
of the header, e.g. (pseudocode):
pjsip_contact_hdr *hdr;
char *hvalue = "<sip:user at host>";
hdr = pjsip_parse_hdr(tdata->pool, "Contact", hvalue,
strlen(hvalue), NULL);
if (hdr == NULL)
// not valid header value
Note that hvalue MUST be null terminated (i.e. the current doxygen
comment/documentation is wrong as it doesn't mention this).
