[SR-Users] Debian: Kamailio: -> FIN - SYN -> on new port

[Kevin Browne]

Hi, am looking for some specific Kamailio help i cant seem to find anywhere
(

#

running Kamailio on Debian/buster ...

##

after receipt of tcp FIN, port is closed.

when signaling is required again from Kamailio side.

Kam is attempting SYN on FINd (closed) port.

this is rejected RST.

How to change SYN to re-establish tcp on new ephemeral port?


##

another description, same problem:

FIN received from (external) cisco (call owner) due to port recycling, not
to keep port open after x minutes. everything is as expected re ACKs and
such.
When Kam wants to send REFER to cisco after the FIN, tcp attempts a SYN (as
we'd expect) but sends SYN on old closed port.

##

Where to change this Kam/OS/other is where i'm attempting to identify, then
figure how to change.

Thank you.
