<p><tt>Hi Dominic,</tt></p>
<p><tt>The 200 OK returned by OpenSIPS should definitely contain a
120s expiry time. Thanks for the detailed explanation - I will
look into this asap.<br>

<div>Hi all, I have the following setup:</div>
<div>-sip device is registering to OpenSIPS setup as a
mid_registrar who then fowards registers to asterisk once
they are authenticated<br>
</div>
<div>-OpenSIPS is setup in contact throttling mode with
outgoing expires set to 3600 sec. <br>

<div>The scenario I came accross is the following:</div>

<div>1-the sip device sends a REGISTER to OpenSIPS (expires
3600)</div>
<div>2-OpenSIPS authentifies the REGISTER and sends back
challenge to the sip device</div>
<div>3-sip devices sends authenticated REGISTER to OpenSIPS,
here the expires would normally be changed to 3600 but in
this case it was already set at 3600.</div>
<div>4-Asterisk receives the REGISTER, alters the expires to
120secs and replies 200 ok to OpenSIPS</div>
<div>5-OpenSIPS forwards the 200 ok but with 3600 sec expires.</div>
<div><br>
</div>
<div>My Questions is:<br>
</div>
<div>I was expecting OpenSIPS to automatically update the
expires in it's usrloc to 120 seconds and send 120 sec in
its 200 ok. Should I be doing something in a return route
for the REGISTERs in order to update that and send the
correct value or should opensips be doing that
automatically? Currently I am calling
mid_registrar_save("location") when I receive the REGISTER
but doing nothing when I receive the 200 ok.</div>
<div><br>
</div>
<div>Thanks in advance</div>
