Adds -x parameter which allows for sip header to radius attributes #38

…t b2bua reads and add's it's contents as radius attribute/ value pairs
a routine (a class really) that B2BUA will execute after call controller is initialized but before any actions are taken. Examples of such routine is one that extracts a specific header, does some simple parsing and adds its contents as radius attribute/value pairs. The syntax for that routine would be something like the following: --pre_auth_proc=HDR2Xattrs[X-foo-hdr] PR: #38

Hey, @twmobius thanks for the idea and sorry for the delay. I have been bit overloaded with other projects and stuff. I liked the idea, but the way it parses a header is bit too "generic" (read hackish), so I would not like to see that in the main b2bua loop. So I extended the original idea and allowed an arbitrary transformation/pre-conditioning routine to be run before we handle over INVITE to the UA stack for processing. This should allow to have all sorts of weird and wonderful things that you and other may suggest as being useful to have. So your original use case would be --pre_auth_proc=HDR2Xattrs[X-Test-Header] |

Hi @sobomax! That's great news, thanks for taking the time! You know, the way you approached the problem could be the start of a plugin subsystem inside b2bua that could allow for arbitrary modification of SIP/ Radius requests (like middlewares or via events - hooks) without having to explicitly accommodate for every weird case out there. |
pre-call-originate ("po_proc") routine to do various
conditioning, such is in this case appending arbitrary
attributes into accounting request. 3 such functions are
provided:
- VAL2Xattrs: append to both originate and answering accounting
requests;
- VAL2XattrsO: append to originate request only;
- VAL2XattrsA: append to answering request only.

This PR adds a new parameter (-x) in the b2bua_radius.py script which allows for the user to specify a SIP Header from which b2bua reads radius attribute/value pairs from. The pairs are being added to the authentication request being created from b2bua.
