Dear SerUsers:
I am running SER 0.9.4 and have just finished reading all the README's of
all the modules, but cannot find what I am trying to do.
I want to check all incoming messages to see if the SIP URI in the "From:"
field is presently registered. I am using MySQL for registration and
authentication. If the SIP URI is the "From:" field is NOT registerd I want
to return a "403 Forbidden" message. I know that From: fields can be
spoofed, but I want to do this anyway.
Does anyone know of an existing module that can help with this? Or of anyway
to do this?

You could probably try the EXEC module, and write a small aplication that
could do a SQL query and return yes or no.

If you are comfortable with modifying the code, you could create your
own "registered_from" function ...
Take a look at the module usrloc (or is it registrar?), where the
function "registered" comes from. The file lookup.c contains the
definition of the function ... just change the header taken (instead
of the ruri, take the From header ... or the To ... or the Contact ...
or ... ) and voila! I did it for my test lab ... it works.
