I think you should tell "what do you want to do ?"
May be guys here can tell you whether Asterisk is the right choice for you or not.
Anyways, talking about SIP and Asterisk, it can do SIP to PSTN (PRI/FXO) and vice versa. Means it can act as a media/voip gateway.
Check this from you referece: http://www.tech-invite.com/Ti-sip-CF3666.html
Remember, Asterisk is a PBX which supports SIP, other protocols and hardwares to interface with PSTN.
Hope this helps little !.

Guillaume, merci beaucoup - thanks a lot.
The links were very useful, especially tech-inivite,
the owner of the site did a great job. I got three
books last night as well: Asterisk, Understanding SIP
(Alan Johnston) and Practical VOIP Security.
>From the books and the website I can only understand
that Asterisk comes in as a registrar/location server.
In other contexts, such as a p2p environment, I assume
that no proxies are used and no location server is
required either.
So my question is again, where does Asterisk fit in? I
can perhaps see that in an incoming call screening
scenario (as depicted here:
http://www.tech-invite.com/Ti-sip-service-14.html)
Asterisk acts as the announcement server. But in other
cases, such as 'transfer unattended' or 'call
forwarding - busy'
( http://www.tech-invite.com/Ti-sip-service-8.html),
there is no apparent need for Asterisk, is that
correct?
I would tremendously appreciate a little more detail
on scenarios where Asterisk is required/used.
