Perhaps your service provider is adding it or something then, but that would be
very unusual. I would have a chat with your network team

Due to some limitations of the nat helper pinger (3 backends, one should
ping at hh:mm:00, the other at hh
Thanks.
This is a network capture taken on Kamailio server that showing VSS
Monitoring ethernet.

This is not a LAN network. UAC is on Internet behind a NAT device so I
can't capture the traffic in the network.
According your message, you think UAC send close notify alerts even during

Hello,
if it happens also between INVITE and 200ok or between 200ok and the
ACK, then very likely sending the OPTIONS will not help. Probably the
far end routers have a broken implementation of NAT.
Is this happening only for a specific group of users, or happens
randomly for different users?

Hello,
Thanks for this feedback.
Here the description of the issue I am trying to solve.
I use already tcp_keepalive.
Call flow is:
UACs --> Nat device --> Kamailio
Transport protocol is TLS.
Kamailio sends TCPs keepalive (tcp_keepalive option) to the softphone
located behind the nat devices
Hello,
nathelper module does ping OPTIONS only for UDP.
For tcp/tls, there is transport layer keepalive:
- https://www.kamailio.org/wiki/cookbooks/5.0.x/core#tcp_keepalive
What is the problem you are trying to solve with this? Maybe there are
some other options for it.
Cheers,

Hi,
Is it possible to send ping OPTIONS over tcp or tls?
If yes, could you me how?

Abdoul.
