Hi,
I'm running an OpenSER server and I've got a couple of usage questions I'd
like some pointers on how I can implement them.
- I want to link multiple incoming telephone numbers to one single account
so 123456 and 45678 and 999933 can all point to the account customer1
Basically I want to do SIP trunking, but with requiring the CPE to
authenticate itself. How do I do this?
- I'm now using an Asterisk server to do some incoming call routing (mainly
some call forwarding scenarios) and I'd like to remove the Asterisk
dependency. How do I retrieve values based on the called destination from a
database? I've tried looking at AVPops, but haven't yet found any clear
documentation on how to use it.
Thanks!

Hi Andreas,
do you want to have this multiple-DIDs aliasing for inbound or outbound
calls (a single user to be able to received calls routed to these DIDs
or a single user to be able to generated outbound calls using any of the
assigned DIDs) ?
For more about AVPops - see the online documentation :
http://www.openser.org/docs/modules/1.2.x/avpops.html
if you have more specific question, please post them here.
regards,
bogdan

Both actually ;-), if at all possible. I want to be able to offer my customers
multiple numbers using a single account where the customer doesn't have to
configure each destination number in his/her CPE. I really want to
authenticate as much as possible so I know I can "trust" the information
coming back from the CPE and don't have to worry about that in the rest of my
system.

I've looked some more at the documentation in the wiki at openser.org and a
couple of the examples I never noticed before were something like what I
want to do. Thanks for the link anyway.

For inbound calls it is rather simple - just use aliases to map the DIDs
over the username.
The problem is for outbound calls - the issue is how the user may choose
the outbound DID. here you can do several tricks:
1) use RPID to advertise the selected DID - user selects the
outgoing DID via an interface on the proxy
2) user change the the CPE cfg to use a specific DID in FROM hdr,
but maintaining constant the auth username to be able to do auth.

Where can I find more information on aliases? I've seen the alias_db module,
but that is just the backend, it doesn't really describe what frontend the
backend supports.

I'd prefer option 2 because that is what I think matches with the way I feel
it should work.

in this case the user will be uniquely identify via the authentication
ID; he can use for SIP ID whatever DID he has assigned (which will get
into From hdr). Authentication will work, but for checking the mapping
between the auth ID and SIP ID use the "user_db" module with uri table.

alias_db provides both frontend and backend - it fully implement alias
support with DB backend (no cache).
you may also consider using the register+location module to get the same
functionality (with permanent contacts) - it may do caching, but more
difficult to provision.

aliases to map the DIDs

Up to now I've been adding additional entries for destination number <->
username relations and it seems to work, but that was for CPEs that register
extra those extra destinations. And it uses the standard usr_loc functions.
Will alias_db magically work? Is there an example I can use as basis for my
configuration? I haven't been able to find one, but that might be my fault.
