Hello,

this might be actually related to tcp connection keepalive:

IIRC, nathelper pings only udp contacts.

Cheers,

Greetings.
May anyone give me advice?
I have working Kamailio with TLS.
It is used by iOS softphone - i developed own one based on resiprocate.
All signalling is TLS.
Almost everything is fine.

But looks kamailio sends CRLF messages sometimes.
If it happens when softphone is in background mode - it is killed by iOS
(as iOS prohibits too often awakes from background mode).

How I can disable these messages?
I see natping_interval = 30 and ping_nated_only=0
Should I set natping_interval to zero ?

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.

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.

regards
Klaus
