The current mechanisms to debug issues in SIP network are not very
efficient. It requires to enable debugging logs across different
devices, recreate the problem and then collect the logs. The idea is
to provide a solution to automatically enable relevant logs (SIP
messages and any other debugging logs meaningful to SIP devices), and
also to indicate where the logs are to be collected or stored. The
enabling of logs will happen at all the SIP devices(upstream or
downstream). This will help to get the logs from all the SIP devices
in a Common logging format (CLF). The solution extends SIP to
provide the infrastructure to enable logging for upstream and
downstream devices with each server deciding how much troubleshooting
information it wants to log - with freedom to simply ignore requests
if required. This document specifies a new header called "Log-Me"
Header in all the SIP messages.
