> Key: ASTERISK-28980
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-28980
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: pjproject/pjsip
> Affects Versions: 13.34.0
> Environment: CentOS 7 with latest updates
> Reporter: newborn
> Assignee: newborn
>
> 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 and drops the session without sending anything to 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.
> No changes. The client continues sending data with TCP Push flag header 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 destroy a SIP TLS/TCP session on the client without restarting the whole asterisk process?
> Here is a tcpdump fragment from client side.
