[Asterisk-java-users] HELP: Fast AGI exed return value.

[Brett S. <bs...@no...>]

Help..................

I've written a Fast AGI application which calls 
BaseAGIScript.exec("txfax", data);

The application txfax is called successfully.

I have two problems.

1. txfax returns a value of -1 but the return from the call to 
BaseAGIScript.exec("txfax", data) returns a value of 0.

2. I have modified app_txfax.c to set a channel variable to indicate 
indicate the actual reason for the failure. When I attempt to retrieve 
the channel value null is returned:

e.g.
<code>
String resultVar = getVariable(SubmitFax.FAX_RESULT);
</code>

where SubmitFax.FAX_RESULT is defined as:
<code>
public static final String FAX_RESULT = "FAX_RESULT";
</code>


The relevant txfax code uses:
<code>
        ast_log(LOG_DEBUG, 
"==============================================================================\n");
        ast_log(LOG_DEBUG, "Fax send not successful - result %d.\n", 
result);
        ast_log(LOG_DEBUG, 
"==============================================================================\n");
        char varResult[64];
        sprintf(varResult, "%d", result);
        pbx_builtin_setvar_helper(chan, "FAX_RESULT", varResult);
<code>

The last lines of the txfax_exec method is:

<code>
    ast_log(LOG_DEBUG, "returning=%d\n", res);
    return res;
}
</code>


The log file displays the following:

Mar  9 22:41:44 DEBUG[18786] app_txfax.c: 
==============================================================================
Mar  9 22:41:44 DEBUG[18786] app_txfax.c: Fax send not successful - 
result 3.

agi://192.168.0.3/CallTxFax.agi?channel=ZAP/g0 completed, returning 0



And if I run ngrep I see the following:
