We have a similar setup where in our case we send username:password
together, as in:
uac_replace_from("sip:username+password@foobar.com<username+password@foobar.com>
");
The whole idea in using the prepaid account setup, as I described to you,
was to have the prepaid account do the authentication for you, such that the
local accounts created from the end user point are not forwarded onto your
provider as your provider will not know what to do with them, and so they
will not authenticate..
What I would suggest is to find out how (in what form) the provider expects
to receive from you (i.e. Openser2 --->Provider). If you are already using
their service you could probably run a trace on a call or use a tool such as
ngrep to see what the packet is doing. You can then reproduce this
functionality however you choose.
The scenario I was reffering to was:
user1 ---
|
user2 --- ---> Openser1 (local accts) ---> replace 'From' with Provider
details (username, etc) ---> Provider ---> PSTN
|
user3 ---
Since the account sent to the Provider is a valid account any way, yo then
should not have to worry about authentication.
There may be a possibility that the provider is doing a SIP Authentication
challenge (e.g. sending a 407 or similar back), in which case you may need
to then send a valid response back. Again you really will have to confirm
this. You will then at least know how to proceed from there.

so when the user register locally openser1,
when he dial to us PSTN
Openser1 sending calls to openser2, its accepting since i made trusted IP
relation
but i got account from provider example XXXXXX password YYYYYY

from the provider
any help on this case

Not sure how you would do this on Asterisk, but what I am doing with
mine (billing by IP) is replacing the from header in the SIP INVITE with a
pre-paid account number for the customer. You will need to load the UAC
module for this, then do something like
if (src_ip=xxx.xxx.xxx.xxx)
{
uac_replace_from("sip:PREPAIDACCTNO@foobar.com");
}
This means that any calls made inbound to OpenSER from that IP address
will have the account number replaced with the pre-paid account number. How
you do billing is then up to you - whether using the Acc module or whether
something can be done on Asterisk, or even a third-party application. I have
heard Asterisk can send DIDs. You can then do something similar for inbound
DIDs from Asterisk.
Just beware this has some rather obvious security issues, so as a start,
you can try having the customer add a prefix to their local account numbers
which you can then authenticate against. If anyone knows of a better way,
please don't hesitate to share.

Hi all

so iam bit confused can some one clarify me how can i achive this
PSTN--OpenerSER(myserver)------------------Customer(Asterisk or ser or
any predictive Dialers)---their clients
1. how can i give access to the customer to call using his IP, and he
can creat internal Number of users
2. how can i account to his IP address billing in Acc
3. how can i forward to DID from myserver to his server blindly
4. how can i bill that DID billing also, for incoming.
