Hi community,

I am preparing a setup of Kamailio with radius accounting on a docker-compose=
 environment. When configuring the acc_radius module I had to navigate throug=
h some old doc by Daniel and inspecting the code itself. The thing is that it=
 seems working, but not. And, yes, I already trying without docker :)

Context: two containers, host newtork, to keep it simple
- one with kamailio + modules (acc, acc_radius with rad_cli) + radius client =
configuration
- another with freeradius + radius client configuration.
I ensure that all data correspond and radius config is fine and spin them up.=
 Run some radius commands to test and let's try some accounting...

Executing a failed call and triggering the account flag method, I receive an =
opaque -1 error from the module:
```

```
Log accounting is working ok, but radius accounting not. Time for troubleshoo=
ting.

I tried to enable client debugging, but the module does not respond. So I mod=
ify the source directly... tested with `radclient` , `radtest`, `radsniff`...=
 all seems to work when trying manually... I also used an internal radcli fuc=
tion `rc_check()` and it works. Meanwhile, I was unable to make it work with =
the module and the radcli library.

So another log output using internal functions to debug the configuration:
```

```
The configuration seems ok, accepted by the library and seems to be applied p=
roperly, but when trying to parse its values... all seems like rubish...
```

```
I'm using `libradcli4 1.2.11-1+b2` for running on the container and `libradcl=
i-dev 1.2.11-1build1` for compiling.

Open to hear ideas, somebody using it actively on latest 5.7 release?
Some updated documentation flying around?
I was thinking to open a GitHub issue to handle the documentation issue.

Thanks in advance!
