BTW can I set interval between these ping packets?<div>I think 4-5 minutes will be good enough to not kill application and retain the connection for some routers...</div><div class="gmail_extra"><br><br><div class="gmail_quote">

Hello,<br>
<br>
this might be actually related to tcp connection keepalive:<br>
<br>

<br>
IIRC, nathelper pings only udp contacts.<br>
<br>
Cheers,<br>

Greetings.<br>
May anyone give me advice?<br>
I have working Kamailio with TLS.<br>
It is used by iOS softphone - i developed own one based on resiprocate.<br>
All signalling is TLS.<br>
Almost everything is fine.<br>
<br>
But looks kamailio sends CRLF messages sometimes.<br>
If it happens when softphone is in background mode - it is killed by iOS<br>
  (as iOS prohibits too often awakes from background mode).<br>
<br>
How I can disable these messages?<br>
I see natping_interval = 30 and ping_nated_only=0<br>
Should I set natping_interval to zero ?<br>
</blockquote>
<br>
Either set the interval to 0 or set ping_nated_only=1 and make sure to not set the NAT flag for the iphone clients.<br>
<br>
A problem may be firewalls/NAT between the iPhone and Kamailio, as they may drop the TCP connection is there is no activity for too long time.<br>
<br>
regards<br>
Klaus<br>
