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 ?
Thank you :)

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.

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

IIRC, nathelper pings only udp contacts.
Cheers, Daniel

BTW can I set interval between these ping packets? I think 4-5 minutes will be good enough to not kill application and retain the connection for some routers...
