Re: [dispatch] Session recording in SIP

[Roni Even <[e-mail]>]

Hi,
I agree that this is an important work but I am not sure about a WG. This
may be done in XCON and AVT.
Note that the recording is not only for point to point call but at least for
three parties like in call center scenarios

I also did not notice any mention of the playback part but it should also be
addressed

This is important work to be done in RAI.  Key management for secure 
recording is an important component that needs to be addressed.

draft-wing-sipping-srtp-key-04 addresses many of these topics.

Thanks,
Alan
