does it make sense for Kamailio to create a connection if a client behind NAT has lost the connection? because It will almost always fail.
It does make sense for IPv6 but not in IPv4 networks.

Ohh, misinterpreted tcp_no_connect=no is tcp_no_connect=0, which is the default.

My other remark related to user location was for the case of tcp_no_connect=yes, which I thought is what was meant initially.

Hello,

do you have tcp_no_connect=no in your config? Because I think the default value is 0.

It is useful when you have client behind the nat that closed the connection, but the contact record is still valid in location table.

Cheers,
Daniel

I'm trying to understand the scenario when `tcp_no_connect` should ever be set to `no`.
Kamailio comes with `tcp_no_connect=no` by default which means it will try (and seemingly always fail) to create an outbound tcp connection when a UAC's tcp connection is lost. This in-turn could start building up the tcp write queue and can be disastrous at scale.
So why would this setting (`tcp_no_connect=no`) ever be useful?
Thanks
