[Serusers] Fwd: Re: AW: AW: [Sipping] FYI: RADIUS & SIP

[Juha Heinanen]

we are using radius accounting, but do not use the records for actually
billing users.  they are available to the users via web interface for
information only.

my opinion is that it is hard to do accounting in a proxy, because it
may not always be on the path of all sip messages.  it is also very easy
to send e.g. a bye message via the proxy that doesn't actually close the
call in modified UAs.

in summary, accounting internet sip calls in proxy is close to
impossible to do and accounting of pstn termination is best to do in the
pstn gws through which also the media flows.
