[Users] Variables

[Douglas Garstang]

All,
 
I can't find any documentation of OpenSER use of variables. I'm sending a lot of info to syslog with xlog(), and with multiple threads (processes?) and multiple calls running, all the output is out of sequence. As a result, I'd like to prefix the debug output with the call-id. The call-id however is very long and I'd like to cut it down and only display a portion of it.
 
How can I extract a string from a SIP message, cut it up, extract the portion I want, and print that portion? OpenSER doesn't seem to have any concept of assigning variables by:
 
variable = value
 
Thanks,
Doug.
