So the question is: Does natping also works with TCP and TLS? Has someone ever tried this?

I have never tried because we don't have nats in my project. Now, if the natping thing updates de expire-timer that the ser tcp core keeps (in the tcp_conn object list), then there is no problem. I mean, the problem is not the nat machine closing the binding ... the problem is ser executing a "close" on the socket. This may either then shutdown the nat binding, or in most end-points mean that no incoming connections can be accepted (most end-points do not support incoming tls call establishment ... they can only connect to a tls server, that is, a sip proxy).

Hi Cesc,
cant this be "fixed" with haveing the natping from server-side? (like sending options requests every say 80 sec? (or even more if you adjust it in the ser's source?)

Mmm ... one comes to mind ... ser/openser will close the tcp/tls connection after a couple minutes of inactivity by the phone ... thus, you either change this in ser's source code or you force your phone to re-register every 90 seconds or so ... otherwise, the tcp/tls connection is closed, thus the phone cannot be reached (for incoming calls).

thanks for the pointer.
Are there known issues for TCP+TLS to work across NAT? The few NAT travesal sloutions I am aware of such as STUN, nathelper+rtp proxy seem to work with UDP only.

Hi,
I am wondering whether SER has any support for TLS as a security mechanism? Thanks,
Yes. It is in the experimental tree: http://cvs.berlios.de/cgi-bin/viewcvs.cgi/ser/experimental/tls/
You can also try openser, which has TLS integrated in the stable version 1.0.0
