Parsing IP and PHONE NUMBER from ACCOUNTING packet

28 Dec 2009

      I am new to RADIUS and have been given the responsibility of managing our
RADIUS server. We use it to process the CDR's that come from our VOIP
switches. I have read the documentation, and googled several search terms
but can find an understandable example.

I would like to parse a VSA from the ACCOUNTING and create a variable that I
can use in the SQL statement.
...
From these fields I need IP and PHONE NUMBER:
I would like to parse the attributes: 

Calling-Station-Id and Called-Station-Id

Here are sample ATTRIBUTE VALUES:

Calling-Station-Id =
"<sip:4784711856@192.168.32.19;user=phone>;tag=20c013a8+1+99ff0002+fdf42201"

                PHONE NUMBER              :  4784711856     ... To a
variable %{orig_number}

                IP                                            :
192.168.32.19 ... To a variable %{orig_ip}

                Called-Station-Id =
"<sip:14787458977@192.168.35.237;user=phone>"

                PHONE NUMBER              :  14787458977   ... To a variable
%{dest_number}

                IP                                            :
192.168.35.237... To a variable %{dest_ip}

My goal is to include the new values in the SQL statement :

.... the new fields above are in the UPDATE statement

        accounting_start_query_alt  = "UPDATE ${acct_table1} SET orig_ip =
'%{orig_ip}', orig_phone = '%{orig_phone}', dest_ip = '%{dest_ip}',
dest_phone = '%{dest_phone}', AcctStartTime = '%S', AcctStartDelay =
'%{Acct-Delay-Time}', ConnectInfo_start = '%{Connect-Info}' WHERE
AcctSessionId = '%{Acct-Session-Id}' AND UserName = '%{SQL-User-Name}' AND
NASIPAddress = '%{NAS-IP-Address}'"

Thanks in advance for your assistance.
