Description
tcp_send_timeout option does not apply for outbound connections.
Reproduction
- Establish TCP OPTIONS between Kamailio and target node.
- On target node block incoming traffic from Kamailio node using iptables.
- Notice on Kamailio node that TCP retransmission packets don't follow tcp_send_timeout settings, instead they fall back to kernel's net.ipv4.tcp_retries2 settings.
