Hello,

RTP proxy is enabled, happened for PSTN termination.
also happpened when 2 SIP client behind the different NAT, or when the 2 SIP client behind same NAT, the BYE message will cause the same error message.

The configuration file is just the same as the file from startup package for RTP Proxy.

you should get some error messages in syslog /var/log/syslog or /var/log/messages. Something happened and openser couldn't process the message. If you do not get something satisfactory, run openser in debug mode:

debug=7
log_stderror=yes

Do you get this situation often or it happens once in a while.

Cheers,
Daniel
