newborn updated ASTERISK-28980:
-------------------------------
Description:
Client establishes a SIP TLS connection to server.
Client IP 192.168.82.32
Server IP 10.2.60.23
We have a some kind of buggy channel between servers.
>From some time, the server stops to receive packets from client.
client continues to push data with no response from server (look tcpdump output from 19:08:18.661449).
When it happens i do the following:
Clean out pjsip.conf (loaded empty one)
then invoked 'module reload'
then restored the pjsip.conf
then invoked 'module reload' again.
Nothing happened, client continue sends TCP Push flag instead of new SYN or Reset/SYN. Router on the server side just rejects this because it does not belong to any session.
How to fix it without restarting the whole asterisk?
Here is a tcpdump fragment from client side.
