<br>answer to your post:<br><br>1. The Database for the Oracle XE version (Carrier Core) looks like this:<br>156 SEQUENCE<br>42 PROCEDURE<br>3 DATABASE LINK<br>1 LOB<br>10 PACKAGE<br>10 PACKAGE BODY<br>76 TRIGGER<br>160 INDEX
<br>103 TABLE<br>16 VIEW<br>18 FUNCTION<br>1 TYPE<br>Whereas the packages contain more procedures (a couple hundred). These are<br>hundreds of thousand lines of PL/SQL code (used language number one...plus a<br>little bit java)
<br><br>The bigger version which will go online soon looks like that:<br><br>303 INDEX PARTITION<br>165 SEQUENCE<br>75 TABLE PARTITION<br>204 PROCEDURE<br>4 DATABASE LINK<br>33 PACKAGE<br>32 PACKAGE BODY<br>1 LOB<br>3 JAVA RESOURCE
<br>187 TRIGGER<br>246 TABLE<br>43 VIEW<br>368 INDEX<br>18 FUNCTION<br>5 JAVA CLASS<br>2 JAVA SOURCE<br>22 JOB<br><br>Also PL/SQL with some Java (perl does not work in Oracle)<br><br>2. The SIP proxy we are using is also an in-house development over the last
<br>6 years and is written in Java and performs really well. And has also over a<br>hundred thousand lines of code and is production stable since 3 years.<br><br>3. java phone which starts over webstart (jnlp)<br><br>4. user interfaces are written in PHP. Sure we could have used perl but PHP
<br>was faster for development due to lots of design in house skills. And this<br>contains admin guis and also website templates to get up and running fast.<br>The customer self provisioning is already huge and just a couple % of the
<br>solution. (there are 26 PHP applications)<br><br>5. For server tasks which do some jobs in the background we have written<br>almost a hundred of perl scripts. Generating invoices, payment interfaces to<br>banks and merchants, asterisk control, log scripts and so on. Perl is really
<br>nice for stuff like that.<br><br>6. last but not least we have an IAX client written in VC++ for windows. And<br>some firewall programs in front of the SIP proxy which are in C and<br>Objective C.<br><br>It is a very large development and we have tried to cut it lean for the
<br>Carrier Core installation. We will add now everyday but not because we have<br>to write it first real quick, but because it is a very large deployment and<br>we need to make it understandable.<br><br>The whole thing is an ongoing development for over 6 years now and is
<br>representing a multi million dollar investment. It is not a small homegrown<br>solution.<br><br>And no, it is not based on Asterisk since Asterisk was not supporting SIP<br>when we started (don't know if it was around). But we are having strong
<br>interfaces to Asterisk because it is an awesome replacement or addition for<br>Cisco Gateways and therefore we also provided fixes for the Asterisk SIP<br>part (with our sister company nikotel, Inc.)<br><br>Best<br><br>
