Can any body help me resolve this error?

Which error? There are two errors. The first indicates that your AGI server isn’t running, or is being blocked by a firewall, or a NAT problem.

The second problem can be caused by broken SIP implementations, but is most likely due to firewall or broken NAT configurations.

Hi Thanks for your response.

I started agi server but still there is some problem.

Here is the log

I can’t find any documentation that allows a script name to be used with FastAGI. Did you mean to use FastAGI?

hitendrasinh · October 6, 2014, 7:10pm

Hi,

Java is used to write dial plan and to manage calls. There is source file called AppSIP.java and converted to AppSIP.class after compilation.

Now there is fastagi-mapping.properties file which has below lines…
AppSIP.agi = com.xxxx.xxx.AppSIP

Now, can you have some idea from given information?

Let me know if you still need anything.

david55 · October 6, 2014, 7:13pm

Don’t know about the Java side, but put the script in the standard AGI script directory and do not use an AGI: URL. Remove any code that supports the use of TCP access to the script.

Previously there was mysqlconnector.jar file which i moved to directly agi-bin dir.

Here you can see SUCCESS instead of UNKNOWN before.

Now i think once i fix java.lang.ClassNotFoundException: com.mysql.jdbc.Driver this then all things will be fine.

Can you please tell me now how can i resolve this error?

Thanks

I have only written AGI in Perl or PHP.
