<div dir="ltr"><div>Hello,</div>
<div> </div>
<div> Up to now I used Asterisk as our pilot phone exchange (around 20 extensions). I am now installing and learnning OpenSIPS/Kamailio to be used as a front end to Asterisk in order to support much more extensions. I have a fe questions:</div>
<div> </div>
<ul>
<li>As far as I see Kamailio and OpenSIPS are quite interchangeable in the sense that I can take the config file from one of them and use it on the other. Am I right?</li>
<li>How do I generate music on hold? I understand that OpenSIPS is not a media server thus it cannot generate it, but can I use Asterisk to generate it? If so, is there an example config for openSIPS and Asterisk?</li>
<li>When an extension is busy I have some code in Asterisk to wait for the busy side to hangup and then generate a call to the original caller (here this feature is called "Call again") using the call files. . Is there some way to generate such a call in openSIPS like the "call files" in Asterisk, or will I have to use Asterisk for this feature?</li>
<li>And a different topic: When using more than one table in a MySQ: server, is there any difference between calling the function modparam("acc", "db_url" ...) for all tables at once, or can I call it for each one separately without having any performance issues?</li>
</ul>
<div> Thanks! __Yehavi:</div>
