The OpenSER standard configuration file is installed at /etc/openser/openser.cfg. It is one of the simplest configuration files for OpenSER. It is the ideal script to start explaining the functioning of OpenSER. There are several sections that you should be familiar with, along with basic modules, parameters, and functions.
By the end of this chapter you will be able to:
Identify the sections of the
openser.cfgconfiguration fileIdentify the limitations of the standard configuration
Use the
ngreputility to track SIP transactionsUse the XLOG module to log the route processing
Use the
append_hfcommand to mark packets tracked in thengreputility
The standard configuration is a good starting point. It has a minimal functionality, it does not support authentication, so you can connect your SIP phones without a password. Anyway, you can call from one phone to another and we will test it later.
