Actions are all run AFTER all conditions are parsed so the nated var is not set yet. you can do a single condition in this case, and set nated for use elsewhere if you need it in the actions. Mike On Mar 26, 2009, at 10:27 AM, Rodrigo P. Telles wrote:

Hi Guys,

I'm trying to do some string matching against a created var and looks like I am doing something wrong but I can't find whats it.

I'm wrote an extension just for tests purposes on dialplan/ default.xml:

<extension name="nat_detect" continue="true"> <condition> <action application="set" data="nated=${cond($ {network_addr} != ${sip_contact_host} ? 1 : 0)}"/> </condition> <condition field="${nated}" expression="1"> <action application="log" data="Action=${nated}"/> <action application="set" data="proxy_media=true"/> <action application="set" data="sip_nat_detected=true"/> <anti-action application="log" data="Anti-Action=${nated}"/> </condition> </extension>

Using two SIP extensions (1000 and 1001) behind NAT and I expected too see "Action=1" on the logs/console, but I'm seeing "Anti- Action=1".

I really appreciate any inputs. I'm using FS 1.0.3 stable.

Look in the default.xml dialplan file for the "tod_example" extension. (It's near the top of the file.) It has an example of how to create an extension that simply sets a variable that can be used in other extensions in the dialplan. -MC 2009/3/26 Rodrigo P. Telles <telles-listas@devel-it.com.br>:
