<tt>Hi Abdul,<br>
<br>
Not sure if this is applicable for us. According to the script
sample, the fr_timer (in seconds) is 10....Is this value too low
for a server to properly reply back ??<br>
<br>
I guess that bug is Kamailio specific. We are on the safe side ;)<br>
<br>
Regards,<br>

<div>Hi Opensips team,<br>
<br>
</div>
I faced instant message timeout issues with MSILO module
while setting SIP IM server using kamailio.<br>
</div>
It turned out that fr_timer values was too low to wait for
MESSAGE delivery to the destination (online/offline both
cases) that server was replying with 408.<br>
</div>
Which result in message sending failed on sending side where
as IM was reaching to the destination.<br>
<br>
</div>
The same issue is true for <a
href="http://www.opensips.org/html/docs/modules/2.3.x/msilo.html#idp5682352"
moz-do-not-send="true">msilo sample configuration</a> for
opensips. <br>
Kindly update it at your end as well. This will save lot of time
for the ones who want to use opensips as IM server.<br>

Good move. You removed the timers so that they
use their default values :)<br>
<br>
Same need to be done in sample msilo script<br>

Hello Abdul,<br>
