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

<p>Dear OpenSIPS-users,</p>
<p><br>
</p>
<p>The table location has the column attr where I use to <span>store
specific additional information for each registration</span>.</p>
<p>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.</p>
<p><br>
</p>
<p>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.</p>
<p><br>
</p>
<p>For the caller, I use to invoke:</p>
<p><br>
</p>
<p><span style="color: rgb(0, 111, 201);">$var(aorChamador) =
$(ct.fields(uri));</span></p>
<p><span><span style="color: rgb(0, 111, 201);">lookup("location","","$var(aorChamador)");</span><br>
</span></p>
<p><br>
</p>
<p>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!</p>
<p>According to the documentation, lookup will <span><span>overwritten</span></span>
the
<span>Request-URI. <span>I guess that is why the SIP
signaling become incoherent.</span></span></p>
<p><span><span><br>
</span></span></p>
<p><span><span>How could I get the caller attr specific
information without side effects?</span></span></p>
<p><span><span><br>
</span></span></p>
<p><span><span>Any hint will be very helpful!!</span></span></p>
<p><span><span><br>
</span></span></p>
<p><span><span>Best regards.</span></span><br>
