<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>
</p>
