Hello,<br><br>Reading through the Wiki:<br><br><div style="margin-left:40px">"Asterisk supports the ability to write dialplan instructions in the Lua programming language. This method can be used as an alternative to or in combination with extensions.conf and/or AEL. PBX lua allows users to use the full power of lua to develop telephony applications using Asterisk"<br>
<br></div>My question is, what is the benefit of using Lua? I recently noticed that OpenSIPS added a compatibility module to use Lua as well. However, where is the real advantage here?<br><br>I mean, you have all these pieces in Asterisk like Lego blocks: AGI Commands, AMI Actions, Dialplan Applications, Dialplan Functions which I think are the ones that really limit what the PBX can do right? <br>
<br>What's the difference between calling them out from extensions.conf or even from extensions.ael and calling them from extensions.lua? What else can you do writing you dialplan in Lua? Could I maybe program N-Way calling* with it?<br>
<br>Are we talking about expanding Asterisk capabilities a huge deal? Or just performance wise during dialplan execution?<br><br>With OpenSIPS I understand its power because you may affect the SIP behavior based on db queries performed by Lua scripts, or modify the next message to be sent, but with Asterisk, you wouldn't be able to modify an ongoing session through Lua based on, e.g., an incoming INVITE to establish a new conference room, would you? Or tell Asterisk to save the Register-CallID of an endpoint as part of the sip peer settings in memory, like the contact ID field.<br>
