Thanks for your Henning, at least I will sleep better knowing I am not completly idiot :-))
I haven't noticed related to INVITE timers (such as the 408) because I only make my client behind NAT to register and re-register and verify it is always reachable in time thanks to this TCP keep-alive. Tomorrow I will try to make a couple a calls to see if I get this 408 you mentionned.
Is there a way (either with a parameter or changing source code) a to control the frequency of TCP k.a. ?
Cheers Pascal

The TCP connection is kept alive and TCP Keep-Alive packets are sent when the TCP connection is idle.
But I don't understand why the time between KA is not linear: [..] Could you explain me where do come from these values of 75 seconds, 23,
54
?
Everything works well: my client behind NAT is kept connected but I'd
like
to understand why it does work :-)
Hi Pascal,
sounds indeed interesting. :-) Perhaps a problem with the internal timers.. Do noticed also other timer related problems, like for internal INVITE 408 replies or similar?
Cheers,
Henning
