I am trying to implement a radius based solution
using FS. I have seen that the mod_radius_cdr module
is actively maintained. so I have a few questions/remarks :

1) When I place a call and my radius server is down, the
call blocks forever instead of just radius_timeout * radius_retries
seconds (I have declared only one server). I would expect that
FS would stop trying to send an Acc Start packet after some
time and get on with the call.

I have not seen this behavior. If you can duplicate this, and propose a patch, it would be gladly welcomed.

I rebuilt and retried and the behavior persists.

The call progress freezes and I get the following in the log :

2009-01-22 20:48:32 [DEBUG] switch_core_state_machine.c:435 switch_core_session_run() (sofia/internal/9333@xxx.xxx.xxx.xxx) State ROUTING
2009-01-22 20:48:32 [DEBUG] mod_sofia.c:130 sofia_on_routing() sofia/internal/9333@xx.xxx.xxx.xxx SOFIA ROUTING
2009-01-22 20:48:32 [DEBUG] mod_radius_cdr.c:152 my_on_routing() [mod_radius_cdr] Entering my_on_routing

After I hangup the client and issue a shutdown in FS I get the following :

2009-01-22 20:50:50 [CRIT] sofia.c:794 sofia_profile_thread_run() Waiting for 1 session(s)

repeatedly and FS never exits.

2) I have also noticed that FS sends only 1 packet (I waited for a minute)
instead of 3 (default in the config) since the first (and second)
attempt failed.
If my server was up (the port was responding) but it returned a req. failed
answer would the above time-out be valid?

I have not seen this behavior.

The same here after the rebuild.

3) When I tried to load the dictionary.freeswitch to my freeradius
server, it complained :

Don't do that. The dictionary is for use with the radiusclient library. FreeRADIUS already includes a dictionary for FreeSWITCH VSAs ( you may need to uncomment it to have it loaded into FreeRADIUS ).

I cannot find any reference to Freeswitch in the freeradius integrated dictionaries (in the share folder). Can you pinpoint the
directory that a dictionary.freeswitch (or other FS related dictionary) resides?

4) The radius attributes included in the current requests are
a) hard-coded, b) limited in number. I think many of us would like to
use more attributes. Or even better define what to include (and what to
put in them) using a
config file (the same maybe?)

This has been proposed. There isn't yet a mechanism, though the intent is to use a general purpose FS VSA for this. The code needs to be added to the mod_radius_cdr module to allow that to be a run_time configuration option.

A general purpose VSA that holds only one value or many? Or a mix (array like)?

5) Does the module send accounting packets only for the a-leg
of a call or for both legs? (Maybe that could be configurable too).

If anyone is interested in the above questions/remarks please post
a reply. I would really like to know how many of the mailing list users
are also interested in FS radius support and your opinions on the matter.

Again, patches are welcome. :)
