Thanks Mark for your answer!<br>If you're using only OpenSER and Asterisk, this means that you pass all your calls through Asterisk and use openser only for authentication and proxying. Is that right?<br>How do you make the calls pass through in NAT environments? Is Asterisk capable of handling that? How?<br>
<br>Too many questions... i know... but i'm excited with that possibility...<br><br>BR<br><br>Nuno<br><br><br><div class="gmail_quote">2008/10/30 Mark Sayer <span dir="ltr"><<a href="mailto:datapipes@avtb.co.nz">datapipes@avtb.co.nz</a>></span><br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">We are running a similar operation but settled on just OpenSER +<br>
Asterisk. All media runs thru Asterisk so MediaProxy isn't required<br>
and a custom billing engine was easy enough to put together. Yes it<br>
uses a lot more bandwidth and CPU but the combination of accurate<br>
accounting and easy NAT transversal make it worthwhile for us.<br>
<br>
The total number of subscribers isn't an issue (there are just<br>
entries in a database) there is no difference between VoIP<>VoIP and<br>
VoIP<>PSTN for us as both are SIP connections. We haven't maxed our<br>
initial Asterisk box yet but anticipate that it will handle about 200<br>
concurrent calls depending on codec translation. A single OpenSER +<br>
database box should be able to handle several Asterisk boxes.<br>
<br>
(I'll also take comments on above, thanks)<br>
