>> where exactly Asterisk 'fits' in my VOIP architecture.<br>I think you should tell "what do you want to do ?" <br>May be guys here can tell you whether Asterisk is the right choice for you or not.<br><br>
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. <br>Check this from you referece: <a href="http://www.tech-invite.com/Ti-sip-CF3666.html">
http://www.tech-invite.com/Ti-sip-CF3666.html</a><br><br>Remember, Asterisk is a PBX which supports SIP, other protocols and hardwares to interface with PSTN. <br><br>Hope this helps little !.<br><br>Vikki.<br><br><div><span class="gmail_quote">

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