I am new to FS and trying to setup a SBC using the example 2 in the FS wiki website. The link is http://wiki.freeswitch.org/wiki/SBC_FreeSWITCH_Configuration_Example_2.
There are parameters in the example that I have to replaces for it to work with my own scenarios. However I have problem understanding the following lines. Is there anyone able to explain what does this mean
<condition field="${sip_redirect_contact_0}" expression="(((192.168.)|(172.24.)|(10.10.))\d+\.\d+(:\d+)(;dtg=\w+)?)">
The bits I am not sure is )\d+\.\d+(:\d+)(;dtg=\w+)?). What does this do?
This will match certain (IPv4) IP addresses, with ports specified:
192.168.x.x:y 172.24.x.x:y 10.10.x.x:y
optionally ending in:
;dtg=xxxx
In the given example, the rest of the XML is executed conditionally on this match. If the sip_redirect_contact_0 matches the expression, then the <actions> are executed, otherwise the <anti-action> is executed.
Regards,
