<p>Have you tried to limit the number with max_contacts() parameter
? if you set the value to 1 it should only keep one AOR per
contact. If that doesn't do what you want you are going to have to
set up some logic to do a lookup foir a previous registration and
manage the contacts that way, probably with a
is_contact_registered function.<br>
<br>
there are plenty of optoins in the register module</p>

<div>Hi , </div>
<div><br>
</div>
<div>I am using opensips 3.4 .</div>
<div><br>
</div>
<div>While saving the contact I have called the save unction as
below . </div>
<div> </div>
<div>
if(!save("location","max-contacts=1,force-registration,path-lazy"))<br>
sl_reply_error();</div>
<div><br>
</div>
<div>My requirement was to save a single contact for a username.
If there will be multiple registration then over ride the
older one with the latest one . </div>
<div><br>
</div>
<div>After this, I can see my calls getting forked between 2
contacts . I can see that the IP addresses of both contacts
are different, but the username part is the same. </div>
<div> <a href="http://user@10.0.0.1:45670"
moz-do-not-send="true">user@10.0.0.1:45670</a></div>
<div> <a href="http://user@10.0.0.2:58095"
moz-do-not-send="true">user@10.0.0.2:58095</a></div>
<div><br>
</div>
<div>This means the system saves both contacts for the user.
Consequently, during lookup, it finds 2 contacts and
simultaneously forks the call to both destinations. </div>
<div><br>
</div>
<div>In my case, the request comes from the ALB, which has a
dynamic IP. Also the call id can be different. If I open
multiple browser tabs and register the same user from both
tabs, the registration will originate with different IPs and
call IDs. </div>
<div><br>
</div>
<div>How I will save single contact in this case ? </div>
