That is interesting. How you set the From header when you send INVITE?
A tag in nua_handle() or in nua_invite()? In any case, according to
the spec it is O.K. to change the From URI as long as the From tag is
kept same.

You need the response sequence number (RSeq) from the 180 response in
the RAck header. The following should work:
{
sip_rack_t rack[1];
sip_rack_init(rack);
rack->ra_response = sip->sip_rseq->rs_response;
rack->ra_cseq = sip->sip_cseq->cs_seq;
rack->ra_method = sip->sip_cseq->cs_method;
rack->ra_method_name = sip->sip_cseq->cs_method_name;
nua_prack(call_handle, SIPTAG_RACK(rack), TAG_END());
}
...but it seems to me that there is no tests for PRACK as a user
method in test_nua. Hmph.
