Hi everyone
I'm trying to implement OpenSIPS-like mid registrar functionality using UAC
module
Up to now, I was simply performing authentication on my kamailio instance,
saving to local domain and forwarding the request to another proxy
I'd like to lower the number of requests sent to this other proxy, by
forwarding only a few of the incoming requests. This is not a problem to
do, but then comes the handling of expiration. If the SIP UAC is
disconnected, the registration expires on my kamailio instance, but I don't
know how to correctly notify the other proxy on the unregistration (I was
trying to build and send a request using uac_send_req(), but this is
useless as I can't set the CSeq value)
While looking for a solution to my problem, I discovered that OpenSIPS had
a mid registrar module doing exactly what I'd like to do (according to the
documentation at least). I also saw old messages on this list that it was
possible to achieve the same result with UAC module on kamailio
In particular, I don't see why (or if) I need to populate the uacreg table.
I don't see why it should be necessary, and it would have a great impact on
performance to use a db for this matter. I also don't need (I think) to
have different local and remote from and to URIs
I think I need to build the a new REGISTER request using $uac_req, but I
don't see any contact header in the outgoing request, despite having set
reg_contact_addr value
Thanks for any clue you could give me

Are you sure it's the wrong list?
1) OP said "OpenSIPS-like" --
2) OP said: "I discovered that OpenSIPS had a mid registrar module

Sounds like you didn't read carefully! No worries, I am guilty of that
all the time on this very list. :-)

Have you tried by setting the CSeq header inside $uac_req(hdrs)?
Then there is the option with t_uac_send() from tm module:

This kind of mapping allows more flexibility, you can set the same
username/domain for remote and local users. But you can also have
mapping on different providers. So I can run my kamailio at asipto.com
with user id daniel(a)asipto.com, which can be then mapped to
TELNUMBER(a)sipgate.com. So my kamailio registers to sipgate.com server
with TELNUMBER and when someone is calling from PSTN the TELNUMBER, the
call is forwarded to my kamailio at asipto.com, which will route it
further to my phone daniel(a)asipto.com.
If you have same user id, the you can eventually skip uac_reg_lookup().
I think I need to build the a new REGISTER request using $uac_req, but
I don't see any contact header in the outgoing request, despite having
set reg_contact_addr value
The $uac_req(...) variable and uac_req_send() function are from the same
uac module but they are independent of uac_reg_*() functions and uacreg
db table. You have to add the Contact header in $uac_req(hdrs) if you
want it the REGISTER generated with $uac_req(...) variable and
uac_req_send() function (or with t_uac_send() from tm).
If you go with the uacreg db table and uac_reg_*() functions, then on
unregister from end point you can use uac_req_disable() to perform
unregister to the remote server. Then there is uac_req_enable() to get
it back registered to the remote server when new registration comes from
end point.
When a registrations expires due to time out, you can have an
event_route executed from usrloc module where you can do uac_req_disable().
I think you have all the pieces that you need to enable/disable
registrations to remote server based on registration/unregistration of
the end point. By setting a larger expires value inside uacreg table,
you should achieve what you look for.

Daniel

I tried, it simply adds another CSeq header, not replacing the generated
one (I also tried with User-Agent header)
I may have to replace it manually on tm:local-request event route
Then there is the option with t_uac_send() from tm module:
I did not know about this uac from TM module
I tried the function, but it doesn't seem to accept variables as
parameters... I must be doing something wrong, it is almost useless if it
can't be used with variables
Thanks

I looked at the code and it is supposed to evaluate variables. Can you
show how you used the function and eventually what was sent to the network?
