I need a way to store somewhere some computed values relative to sip messages. That is, I need some kind of "variables"!

I need to access to these "variables" both from a custom SER module and from the ser.cfg script.

I think that the solution are AVPs. Am I right?

yes

But I'm a little confused about the many "incarnations" of the AVP. After looking a little around I have understood that from inside the module I have to use the functions in "usr_avp.c". Am I right? Then there are the "avp" and "avpops" modules.

My question is: they all refer to the SAME avps?

yes

Thas is, if I save an avp value by means of "usr_avp.c", then I can access the SAME avp by means of "avpops"?

yes

Or they are different and separate implementations?

avp and avpops modules are different and separate implementations in the meaning of design and features, but both are dealing with usr_avp. The features of avpops are documented in module's turorial at: http://www.voice-system.ro/docs/avpops/

Thanks.

P.S. I'm using SER 0.9.3.
