<br>Hi Daniel, thank you for looking into this. I understand what you are saying and what is happening is very similar.<br> The linksys is set to 10 secs, so around 8 secs it sends a new registration. Kamailio replies with 30 but the linksys <br>ignores it and keeps sending the registration every 8 secs. But the fact is that the AOR is being updated every <br>8 seconds, as you can see below [at the bottom of the email], which can be a problem with a lot of customers <br>and registration interval of 2-3 secs.<br><br><br>mysql> select username,contact,received,expires,cseq,last_modified,user_agent from location where username =

Hello<br>
<br>
This is how my registrar module is configured, hoping that
min-expires set to 30 wont allow registration attempts more
often than 30 seconds, but if I configure a UAC to register
every 15 seconds I see that kamailio allows it. Shouldn't it
reply with "422 Session Interval Too Small" or "423 Interval Too
Brief"?<br>
</div>
</blockquote>
it will not allow a REGISTER with Expires value less than 30sec. But
even the phone sends a REGISTER with Expires 3600 (for example), it
can send again in 10 sec another REGISTER with Expires 3600. In
order to see if there is something incorrect, send us full REGISTER
requests and the replies.<br>
<br>
Cheers,<br>
Daniel<br>
