I don't believe there is a way to pull multiple values back from the call to api:execute. However, Lua has native pattern matching with captures. Here are a few resources for you:<div><br></div><div>FreeSWITCH book, pages 149-151</div>
<div><a href="http://www.lua.org/pil/20.3.html">http://www.lua.org/pil/20.3.html</a></div><div><a href="http://www.lua.org/manual/5.1/manual.html#5.4.1">http://www.lua.org/manual/5.1/manual.html#5.4.1</a></div><div><br></div>
<div>Here's a simple example that you can actually run with "luarun" if you want to do some testing:</div><div><br></div><div><font class="Apple-style-span" face="'courier new', monospace">-- pattern.lua</font></div>
<div><font class="Apple-style-span" face="'courier new', monospace">data = "1234#5678";</font></div><div><font class="Apple-style-span" face="'courier new', monospace">_,_,var1,var2 = string.find(data,"(%d+)#(%d+)");</font></div>
<div><font class="Apple-style-span" face="'courier new', monospace">freeswitch.consoleLog("INFO","\ndata: " .. data .. "\nvar1: " .. var1 .. "\nvar2: " .. var2 .. "\n");</font></div>
<div><br></div><div>Output:</div><div><div><font class="Apple-style-span" face="'courier new', monospace">freeswitch@internal> luarun pattern.lua</font></div><div><font class="Apple-style-span" face="'courier new', monospace">+OK</font></div>

<div><font class="Apple-style-span" face="'courier new', monospace">data: 1234#5678</font></div><div><font class="Apple-style-span" face="'courier new', monospace">var1: 1234</font></div><div><font class="Apple-style-span" face="'courier new', monospace">var2: 5678</font></div>

Hello!<br>
<br>
How can I use regexp with LUA scripts? Yes, I found I may use<br>
api:execute('regex'....) but can't understand how to get matched strings<br>
from it. For example my re is (\d+)#(\d+) and I want to get $1 and $2 in<br>
some variables.<br>
<br>
