The module implements global flags. The difference between the
|
|
global flags and flags that can be used in the configuration file
|
|
or AVPs is that they the scope of the global flags is not limited
|
|
to the SIP message or transaction being processed. Global flags are
|
|
always available, their contents is not forgotten when a SIP
|
|
transaction gets destroyed in SER.
|
|
</para>
|
|
<para>
|
|
Global flags can be accessed from the configuration script, for example:
|
|
</para>
|
|
<programlisting>
|
|
if (is_ugflag("1")) {
|
|
t_relay_to_udp("10.0.0.1", "5060");
|
|
} else {
|
|
t_relay_to_udp("10.0.0.2", "5060");
|
|
};
|
|
</programlisting>
|
|
<para>
|
|
The value of the global flags can be manipulated by external tools
|
|
such as the web interface of SER or cmd line administration
|
|
tools. One particular application of global flags could be runtime
|
|
configuration changes without the need to restart SER.
