[OpenSIPS-Users] How to invok lookup() and get attr from the caller, without side effects?

[Răzvan Crainea]

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,
