[Users] DID Handling -> Transitioning from Asterisk/SipX

[T.R. Missner]

Max,

We are doing this same thing but our method is somewhat of a hack.
We effectively use a system call from within the cfg script to lookup
the DID in a postgres db.
The lookup returns the domain the DID belongs too ( our customer's
switch ).
We then re-write the RURI and forward the message along using t_relay.

This is a simplification but I think you get the point.

I would also like to know if there is a more 'proper' way to accomplish
this lookup.

The difference between what we are doing and what it seems openser was
built to do is the lack of registrations.
If we implemented registrations then I think we could use the userloc
module.
Am I right about this?

Is there a better way to implement 'static registrations'?

T.R.

Subject: [Users] DID Handling -> Transitioning from Asterisk/SipX

Hi all,

As our requirements scale (number of DIDs, number of users, number of
simultaneous calls, etc) it is very apparent that our needs require us
to move from a softswitch/pbx application environment onto a Sip Router
based platform. While I have been able to run though the documentation
and bring online a working OpenSER platform I am still confused about
DID handling in the system.

I need to be able to take a series of DIDs that we are being passed from
the carrier and forward the call to the end user's switch untouched
(i.e. 18005551212 at me needs to be passed to 18005551212 at customer). I have
been reading through aliasing but this does not seem to be what I need
(because the customer's switch does not see the original DID). Ideally I
need to be able to maintain a large inventory of DIDs and assign them to
customers without touching the configuration files when the association
is made.


How do I accomplish this? What do I need to add/configure in the system?
How do I configure this redirect/mapping/proper terminology correctly?

Thanks in advance,
Max
