[OpenSIPS-Users] CDRTool + RTPProxy - Media Based Accounting

[Eduardo Lejarreta]

Good morning Nick.

Saving RTP streams to media_sessions table -> this done through "config.ini"
mediaproxy configuration file. -> "accounting = database"
You should do cross check in background because you have to wait DB
registers to be written by "acc" and "media_sessions" tables. For real time
on-line behavior you should use Radius accounting.

Regards.

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.
