4. Your problem:

I know that this problem is discussed in another topic, but it seems to be a dead topic, and no solution has been found
http://www.brekeke-sip.com/bbs/viewtopi ... ight=twice

I have the following dialplan:
Matching:
$request=^INVITE
To=(.+)
$dialplan.findtonumber( To )=(.+)

Deploy:
$session=com.adp.dialplan.plugin.adpfordialplan %1
$target=myTarget
To=sip:45440\#%2@myTarget

As you can see I have a session plugin which handles the billing. In addition to that I have a dialplan plugin which modifies the destination number based on some internal rules of mine.
The problem is that the dialplan plugin
$dialplan.findtonumber( To )=(.+)
is called twice. I'm writing to a file within the plugin code, and from that I can conclude that the plugin is executed twice for each incomming call.
Does anyone know how to avoid this?

Thanks,
Troels

Do you have another DialPlan rule definition which calls $dialplan.findtonumber? If so, disable it.

No I do not - this is the only rule.

When you make a call to the SIP Server, how many sessions can you see in [Active Sessions] page?

One - only one.

I tried it in my environment.. but my plug-in was called once.. it seems no problem.

if possible, paste your code here.

Yes, here is the code in dialplan.findtonumber

Code: 

    static public String findtonumber(String[] arg, com.brekeke.net.sip.SIPpacket sippacket, Properties pr) throws Exception
    {
        String strSIPto = stripCalleeURL(sippacket.getValue("To"));
        int iCallPatternID = Integer.parseInt(sippacket.getValue("X-callpatternid"));
        
        //Adding leading 0 to all Italian landline numbers
        if (iCallPatternID == 14848)
            strSIPto = ItalyLandline(strSIPto);
        try
        {
           FileWriter fil = new FileWriter("c:/ondo/test/" + evstat.callid  + "-findtonumber.txt", true);
            PrintWriter ud = new PrintWriter(fil);
            ud.println(strSIPto);
            ud.close();
         }
         catch (Exception e2)
         {
         }
        return strSIPto;
    }
In the output in the textfile I can see that there has been written twice for each call.

Thanks.

Hi

I looked at the above source code and tried the same plug-in in my environment, but I did not get any issue.
It means the plug-in was executed once with a call and the text file was written once.

If you use a packet capture (e.g...Wireshark), how many INVITE can you see when you make a call?
