I do use scripts for small no so much used<br>much simpler stuff though, e.g: a lua script takes care of authenticating users<br>when doing international calls from company extensions in the hosted PBX solution.<br><br>The other reason i chose to do<br>this as a module because C is the language i feel more comfortable with.<span class="ecxApple-converted-space"> </span><br>i hope this clarifies i little bit this.<br><br>Moving on, right now i m developing on a test freeswitch that we have and yes i noticed<br>that subscribing to the CS_INIT event does represent a big problem<br>because i get notified for every single of those events that is generated on<br>freeswitch which would be very inconvenient because as i mentioned, the same<br>switch does many other things that i m not interested in, so i m going to try the advise<br>provided and try to do it in the dial plan, i will explore this option.<span class="ecxApple-converted-space"> </span><br><br>thank you very much all!<br><br><br><br><br><br><div>> Date: Thu, 5 Mar 2015 14:19:51 +0100<br>> From:<span class="ecxApple-converted-space"> </span><a href="mailto:ssinyagin@gmail.com">ssinyagin@gmail.com</a><br>> To:<span class="ecxApple-converted-space"> </span><a href="mailto:freeswitch-users@lists.freeswitch.org">freeswitch-users@lists.freeswitch.org</a><br>> Subject: Re: [Freeswitch-users] sessions and CS_INIT events<br>><span class="ecxApple-converted-space"> </span><br>> but for the task that OP has described, writing (and maintaining it in<br>> the long term) a module is really an overkill.
