Hello Eduardo,

Thank you so much for your response!!!! I have not had a chance to
further look into
the mediaproxy or rtpproxy modules regarding this issue however, will
do so in the
next few days.

Would it be possible to provide a snippet of the opensips scripts that
include the
mediaproxy implementation that you explained above:

* Saving RTP streams to media_sessions table
* Do you cross check "media_sessions" with "acc" for the various
instances (early media, re-invites, T38)using OpenSIPS script? Or is
this done in background directly on the database?

As you would imagine, we already have ACC module working, and looking
how to integrate  media accounting using RTPProxy if possible, or by
somehow patching mediaproxy to work behind NAT.

I really hope the folks from RTPProxy or AG could comment on this kindly.

Regards,

Nick.
