[SR-Users] TCP Keepalive for NAT'd Clients

[Daniel-Constantin Mierla]

Hello,

you can set per tcp connection lifetime using tcpops module:

   - https://www.kamailio.org/docs/modules/stable/modules/tcpops.html

You can do that when you get the INVITE, before sending a negative
response from kamailio.cfg. Or, if you relay the invite, set a failure
route for it and do the operation there.

Cheers,
Daniel
