[OpenSIPS-Users] Relay Subscribe/Notify for MWI

[Sidwell, David]

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
