Hi, Rodrigo!
Can you print the $ru variable before and after each lookup() query?
Something like:
$var(ru) = $ru;
xlog("R-URI before caller lookup: $ru\n");
lookup("location", "", "$fu"); # this takes the caller from FROM uri,
which I think is more suitable than from contact uri
$ru = $var(ru);
# continue your processing here
xlog("R-URI after caller lookup: $ru\n");
...
# now do the real lookup for the callee
xlog("R-URI before callee lookup: $ru\n");
lookup("location");
xlog("R-URI after callee lookup: $ru\n");
Make sure they are all correct, or if they are not, send me these logs.
Thanks,
Răzvan Crainea

Hi Sevpal.
Yes. That is what I was doing. It worked very well.
But, nowadays I'm using db_mode = 0 for usrloc. So, the information is
always only in RAM. In this case, the query will return no result.
That is why I'm trying to read the attr column from table location,
from RAM, and get specific information for the caller.
For the callee, everything is all right.

Hi, have you tried/considered running a simple query on the database
and parsing for the information you need?

Hi Răzvan.
I have tried that idea. But that didn't work. The SIP INVITE message
is being changed by the OpenSIPS in a wrong way, in my point of view.
Do you know some way to save the entire SIP INVITE message before
calling lookup() and then make the saved message take place after the
lookup() execution?
My original message is:
INVITE sip:[email protected] SIP/2.0

This is being changed to:

So, the caller is receiving its own SIP INVITE.
That is why when A calls B, is A that rings, not B.
It is becoming a bit complicated. So, I suspect I'm going to the
incorrect direction....

Hi, Rodrigo!
Have you tried restoring the R-URI after the caller lookup? Something
like:
$var(ru) = $ru;
lookup("location", "", "$fu"); # this takes the caller from FROM uri,
which I think is more suitable than from contact uri
$ru = $var(ru);
# continue your processing here
....
# now do the real lookup for the callee
lookup("location");
Don't do the lookups in the reversed way, because you might loose some
contacts.
Best regards,

OpenSIPS is more than a SIP proxy/router as it includes
application-level functionalities.

Dear OpenSIPS-users,
The table location has the column attr where I use to store specific
additional information for each registration.
Whenever A calls B, I have to read this specific information from the
A record and from the B record. That is, I need to get and handle
specific information about the caller and callee.
For the callee, I use to invoke the lookup("location") function that
put the needed information in the attr_avp. That is good and works
very well. Then, I just have to read the attr_avp to get such
specific information.
For the caller, I use to invoke:
$var(aorChamador) = $(ct.fields(uri));
lookup("location","","$var(aorChamador)");
However it causes amazing side effect in the SIP signaling. Ex: When
A calls B, B stays quiet and A rings. So A can answer A. Crazy!
According to the documentation, lookup will overwritten the
Request-URI. I guess that is why the SIP signaling become incoherent.
How could I get the caller attr specific information without side
effects?
Any hint will be very helpful!!
Best regards.
