Using a web server to handle XML CDRs
One feature of FreeSWITCH's mod_xml_cdr is that it can use HTTP POST actions to send CDR data to a web server, which in turn can process them, and perhaps put them into a database. This mechanism has several advantages:
- Modern web servers can handle enormous amounts of traffic
- Multiple FreeSWITCH servers can post to a single CDR Server
- Multiple web servers can be set up to allow failover and redundancy
It will automatically retry in the event of a failure, on the same web server or on another web server. Eventually, if all the retries on all the web servers fail, it will write to the disk so that the record can be processed later.
The recipe presented here will focus on the steps needed to get a web server set up to process incoming POST requests with XML CDR data.
Getting ready
You will need an operational web server that you control. Most Linux/Unix and Windows systems can get an Apache web server installed. Detailed instructions on configuring a web...
