Dmitry,<br><br>FreeSWITCH can definitely help you with all of this, HOWEVER, there's a lot in this scenario that isn't specifically FS. Let me ask you this question: do you have a programmer that can handle the interfacing necessary with FS? I believe you will need to read up on a few things:<br>
<br>Auth all SIP clients from external db - <a href="http://wiki.freeswitch.org/wiki/Mod_xml_curl">http://wiki.freeswitch.org/wiki/Mod_xml_curl</a><br>Call control - <a href="http://wiki.freeswitch.org/wiki/Event_Socket">http://wiki.freeswitch.org/wiki/Event_Socket</a><br>
LCR - <a href="http://wiki.freeswitch.org/wiki/Mod_lcr">http://wiki.freeswitch.org/wiki/Mod_lcr</a><br><br>I can tell you that there isn't already a whole package with all of this, but rather just some of the individual components that will need to be put together. Will you also need a billing system? If so you'll need to make sure that you can handle CDRs. You have multiple choices there as well. FS does not support logging directly to a backend database, but it does support generating CDR records that are "INSERT INTO..." commands that can easily be run to autopopulate your CDR table. There's also XML CDRs which allow for extremely specific parsing of call history. The catch is that you need a good XML parser and some business logic to make sure that this information is all useful to you.<br>
<br>Hope this helps!<br>-MC<br><br><div class="gmail_quote">On Sun, Dec 21, 2008 at 11:08 PM, Dmitry Mordovin <span dir="ltr"><<a href="mailto:d.mordovin@dwide.com">d.mordovin@dwide.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Hi Friends!<br>
<br>
I wish to do something like:<br>
- Authorize all sip clients in external DB, for example postgresql.<br>
- Control each call session duration, just like prepaid calling card.<br>
- LCR, if one voip provider can't connect call into PSTN, try next
PSTN supplier.<br>
<br>
Please help me, i can't understand what is docs i might to read to know
how to do it.<br>
Could you show me some links and terms. explain it?<br>
