Thanks David for your answer, but can you explain how radius can do that
since sending BYE messages is more at the signaling level. I dont quite
understand how radius can even communicate at the SIP signaling level.

You could use radius.

Hello,
In "/doc/PREPAID.txt" it talks about "an external call control
module
(not provided by CDRTool) that maintains call status and terminates calls by
sending BYEs to both SIP end-points"
What is this 3-party module and where can I get it?

Of course Radius itself can't do it.
There is a related project that I've not tried but it could be what you are
looking for:

Thanks Iñaki for your suggestion. After reading the documentation at the
site you mentioned below I now understand that the "external call control
module" that is discussed in "/doc/PREPAID.txt" of CDRTool is a modified
freeradius radius server which is "able to connect on the CDRTool prepaid
engine through TCP API and implement a basic prepaid level for calls passing
through OpenSER" and it is able to send "information back to OpenSER through
the recommended way of SIP-AVP. The avps received will be available in
openser as: callMaxDur and credit, where callMaxDur is the maximum duration
the user is allowed to be connected with the destination and credit
represents the amount of credit available at starting of the call"
Now going back to my question about this module that is able to "maintain
call status and terminate calls by sending BYEs to both SIP end-points" this
means that once the "callMaxDur" and "credit " information is sent
back from
freeradius to OpenSER, OpenSER is the one "sending BYEs to both SIP
end-points". How can I make OpenSER do this? How can OpenSER use the
callMaxDur information sent in the SIP-AVP pair to terminate a call with a
BYE after X amount of minutes?

Hi Matteo,
I was in the same position like you are now, months back.
At least in OpenSER (please note that 1.4 is no longer tagged as OpenSER,
but Kamailio) it was hard to do call-control since SER like was not
initially developed to be dialog aware server. Dialog module is coming
slowly to be there but I have the feeling it will take a bit time more to
have a mature product out.
In the mean time I decided to go with an easier approach, so have installed
Yate ( I am sure Asterisk or Freeswitch can do the same job as well, but it
is just about having yate on hands on that time). In my case Yate will take
the timeout value from Private SIP Header and process it as global timer of
the call (Yate acts as SBC or B2BUA). If the call does finish before the
timer is hit, Yate will do the job and disconnect both legs of the call
(inbound and outbound) by sending BYE to both parties, therefore reaching
the scenario wanted. However, this is considered like a security whole in
Yate since anyone could achieve call disconnects by using the right private
header, so u must set also an ip acl inside yate for the calls where u
process the private-timer header.
I am at your disposal if you need further help with freeradius-cdrtool
connector (planning to release out a new version soon, just hope that the
time will stay still to give me that opportunity ;-) ).

DanB

They can not, because H.323 does not allow "custom-headers" you could
only use the "standar ones", H.323 it's a binary protocol, so no way
to add customs headers and "magicatly" they appears on the UAS side.

Our scenario it's simple and also very common:
- User go to the website and register for a new prepaid-account
- User get it SIP credentials and config data
- User go to him Asterisk PBX and configure him's account
- User IS a SOHO with 10 employers with 10 SIPPhones behing their
Asterisk PBX
So .. now .. how do you control that if they have 10€ on their account
and the 10 employers beging to do calls outsite, the credit runout on
a middle of 2 (for taking the simplest scenario) simultaneous calls
from that user to the PSTN world.
How do you control that on your scenario? you give each account a
call-limit of 1 ? ... do you give them 10 accounts instead of 1 ? and
on that case, again ... how do you control that 2 accounts from the
same "USER" do not runout of credit ?
P.D.: Please, only reply to the list, not need to CC me, I'm

Apologies for the Me Too post, I would also find this very useful as I

this situation really make sense, restricting to one call per user is not
worth
since the more usage is the more provider make the money
only concern from provider side is, how to restrict them the balance they
have
this is big concern of all the providers, iam also digging the same issue.
can some one come across any solution, kindly post back it will be good to
hear back.
await for the solution
DanB :-) i have look at the module created using yate, looks good asper the
document.
may be if you add the option of mulitple calls would be good option.

calls from the same user.
And how would you treat such scenario?

We've found the only way to do this accurately is to use a B2BUA like Asterisk.

Thanks Iñaki for your suggestion. After reading the
documentation at the
site you mentioned below I now understand that the "external call control
module" that is discussed in "/doc/PREPAID.txt" of CDRTool is a modified
freeradius radius server which is "able to connect on the CDRTool prepaid
engine through TCP API and implement a basic prepaid level for calls passing
through OpenSER" and it is able to send "information back to OpenSER through
the recommended way of SIP-AVP. The avps received will be available in
openser as: callMaxDur and credit, where callMaxDur is the maximum duration
the user is allowed to be connected with the destination and credit
represents the amount of credit available at starting of the call"
Now going back to my question about this module that is able to "maintain
call status and terminate calls by sending BYEs to both SIP end-points" this
means that once the "callMaxDur" and "credit " information is sent
back from
freeradius to OpenSER, OpenSER is the one "sending BYEs to both SIP
end-points". How can I make OpenSER do this? How can OpenSER use the
callMaxDur information sent in the SIP-AVP pair to terminate a call with a
BYE after X amount of minutes?

Thanks David for your answer, but can you explain
how radius can do that
since sending BYE messages is more at the signaling level. I dont quite
understand how radius can even communicate at the SIP signaling level.
Of course Radius itself can't do it.
There is a related project that I've not tried but it could be what you are
looking for:
