Hi All,
I'm having to work with another SIP UAS acting as a location server, and I have ser as my 'frontend' so all clients talk to ser, and ser will register and with the location server.
In my logs I see the warning: Jul 15 14:26:31 frig /usr/local/sbin/ser[18931]: WARNING: upstream bug - 0-terminated packet
This happens when I t_relay my REGISTERS to the 3rd party location server. The packets look fine to me. Any ideas?
Here follows a trace (from ngrep), the logs from syslog, and our ser configuration. I'm aware that the location server is not challenging on REGISTERS :)
Thanks! -Jev

It is what it tells to be -- the received packet is broken in that it includes a zero character in the end. We honor such request but issue a warning about them. use "ngrep -x" to inspect the packet in hexcode.

Thanks Jiri,
For my edification, which standard is this actually violating? RFC3261 or other?
Thanks again, -Jev

It is what it tells to be -- the received packet is broken in that it includes a zero character in the end. We honor such request but issue a warning about them. use "ngrep -x" to inspect the packet in hexcode.
