David,
Do you use the "uac" module to do the changes over the TO/FROM headers or ??

Hi Bogdan,
Currently the SUBSCRIBE is not handled locally, but forwarded to a
server which implements RFC 3842.
In my application, the UAC’s register with OpenSIPS (Registrar module)
which in turn registers them with the external server (Registrant module).
The TO/FROM headers of further requests are modified to reflect the
domain of the server and the requests are forwarded to the server.
In-dialog responses are automatically modified with the reverse
modifications and forwarded back to the UAC.
This works fine for all requests except the SUBSCRIBE/NOTIFY.
Ideally the re-SUBSCRIBE would contain the same modifications, and the
NOTIFY’s would have the reverse modifications.
(I am OK with manually making the transformations, but the
re-SUBSCRIBE’s do not seem to be processed via the route script)
I am open to a solution where opensips handles the subscribes
(presence_mwi?), but I don’t see any way I could retrieve the MWI
indication from the server.
Thanks,
Dave

Hi David,
How do you change the TO / FROM hdrs in initial SUBSCRIBE ?? Is the
SUBSCRIBE handled locally (opensips as presence server) or you forward
it further ?

Hello,
I am using OpenSIPS in an application relaying SIP messaging
between clients and server with modifications to the “To”, “From”
and “Contact” headers.
This is working well for call control, however the server also
provides MWI via Subscribe/Notify, and unfortunately this does not
work properly.
There are two basic issues:
1.Although the initial SUBSCRIBE can be modified and relayed
successfully, it cannot create a dialog. Any subsequent
“in-dialog” re-subscription messages seem to be automatically
relayed but the “To”, “From” and “Contact” modifications are not
included. These re-subscribes do NOT go through the configuration
file route script so there is no opportunity to make any
additional modifications.
2.“In-dialog” NOTIFY messages from the server do not get routed
back to the client, but appear in the configuration file route
script with “totags”. These can be manually routed back to the
subscriber but any attempt to modify the To and From headers fails
(due to the presence of the totags).
Questions:
-Is there any way to configure OpenSIPS to allow for automatic
relaying of the Subscribe/Notify messages in an application such
as this?
-Is there a way to make use of the Presence modules to achieve the
same function (The server will not issue PUBLISH commands).
Thanks,
Dave
