Here it goes, apologies for the length:
The registration process is done via TLS and therefore I "can not" post the trace. However, the resulting data is the following:

What I was refering to is that in the logs the lookup process is using sip:sam@M.N.O.P, which is not found because what exists in the registrar database is sam@domain.com. In the Contact header of the 200 OK the local IP is used instead of the FQDN form. I might have been misleaded by the logs or the gruu lookup process, but in the following lines of the code (you were right about the lines and verion):
The first log ouput comes from the following lines of lookup.c:
120 if(puri.gr_val.len>0) { 121 /* pub-gruu */ 122 inst = puri.gr_val; 123 LM_DBG("looking up pub gruu [%.*s]\n", inst.len, inst.s);
But afterwards, there are these lines, with the return -1 statement: 154 /* aor or pub-gruu lookup */ 155 ul.lock_udomain(_d, &aor); 156 res = ul.get_urecord(_d, &aor, &r); 157 if (res > 0) { 158 LM_DBG("'%.*s' Not found in usrloc\n", aor.len, ZSW(aor.s)); 159 ul.unlock_udomain(_d, &aor); 160 return -1; 161 } 162
This is the point where I would need expertise help, because it looks like it uses the "short" AoR (without URI gruu parameters) according to the logs and a -1 is returned. Afterwards there are the lines used to lookup the pub and temp gruu but are not, as far as I understand, used because of the return -1.
What is my mistake in the above assumption?
Thanks a lot for the amazing fast reply.
Samuel.

Hello,
can you send a trace that includes the registration as well as the call?
The pub-gruu is using the AoR, iirc.
Also, the line you refer to is not matching anymore with latest 4.1.x -- paste the code around it to locate it properly.
Cheers, Daniel

Hi all,
I'm having some issues treating requests within dialogs with gruu enabled with kamailio 4.1.2.
I've got the "standard" configuration of WITHIN route with the adition of the next lines:
if(is_gruu()){ route(LOCATION); };before the the RELAY route call in the loose_route section.
The "problem" is that the ACK with a pub-gruu on the Req-URI is not properly lookup. In the logs I can see the following statements: 2(4232) DEBUG: registrar [lookup.c:123]: lookup(): looking up pub gruu [urn:uuid:d63b1c4f-d7dc-4f4e-87f1-948123266dc0] 2(4232) DEBUG: registrar [lookup.c:158]: lookup(): 'sam@A.B.C.D' Not found in usrloc
Where A.B.C.D is the local IP of the UA.
Looking at the code, this last line looks like is looking for the "standard" URI (username@domain) instead of using the pub gruu. Am I right with this assumption or am I missing something from the code? As far as I could look, it looks like there's an exit -1 statement in the line 158 of lookup.c which disables the following gruu treatment.
Since the username with IP is not registered, this ACK is lost and the sesion is not stablished (lost ACK).
Can anyone provide some hints why is this failing?
Thanks a lot in advance! Samuel.
