USTelecom has put on a free webinar about this, with guests from VeriSign.
It might be on interest.

Subject: voip calea interfaces

I'm looking into the FCC ruling to require CALEA support for certain
classes of VoIP providers, as upheld by the DC circuit court a couple of
weeks ago [1]. The portion of VoIP that is covered by this order is pretty
narrow (ie, you provide telephony-like voip services for $$ [read the
specs for the real definition]), and the FCC is looking at narrowing it
down further but has not done so yet. Meanwhile, the deadline for
implementation -- May 14, 2007 -- is starting to get pretty close.

The operational part of this subject, and the reason for this mail, is the
implementation of the wiretap interface. Obviously there are going to be a
range of implementation approaches, given that there are a wide variety of
providers. I mean, big-switch users probably just enable a feature, but
small providers that rely on IP PBX gear with FXO cards will have to do
something specific. Are vendors stepping up to the plate? Did you even
know about this?

Off-list is fine, and I'll summarize if there's interest.
