[reSIProcate] Stack sends a 400 Bad Request()

Tue Mar 13 11:23:20 CDT 2007

Byron,

No, we aren't currently using this pre-processor. I'm happy to turn it on if
you think it will help.

Regards,

Rob.

I am having a hard time finding a code-path that could be doing this without
writing any logs. Did you enable PEDANTIC_STACK by any chance?

Best regards,
Byron Campen

All,

Can anyone spot the problem with the received INVITE in this trace? If we
use the older 0.9.0 version of the resip stack the INVITE is not rejected.
I've tried with resip 1.1-RC2 and this is the result. 

I'm unsure about the top most Via header but we have tried by-passing this
proxy and the result is the same.

Regards,

Rob.
