[sr-dev] gruu lookup

while testing tryit client, i started to wonder how lookup is done when request uri of an in-dialog request contains a public gruu such as in this: BYE sip:bar@test.fi;gr=urn:uuid:38056f74-308b-42c9-b16d-0fa61b6ff1a1 SIP/2.0 registrar/lookup.c has: if(puri.gr.s==NULL || puri.gr_val.len>0) { /* aor or pub-gruu lookup */ ul.lock_udomain(_d, &aor); res = ul.get_urecord(_d, &aor, &r); ... why is lookup done based on aor bar(a)test.fi instead of gruu urn:uuid:38056f74-308b-42c9-b16d-0fa61b6ff1a1 found in location/instance field? -- juha
