Hello,

I'm using the last version (git) and I have another case of missing notification .

I have compared log of working and not working case, both time DTMF event was detected (line bellow in blue) but the creation of the NTFY message is not present (line in RED) in the not working case

for the moment I cannot reproduce the error on my test server, I can only reproduce them on production and mostly when I have many calls, so maybe it's depending of the load of the server.

any idea ?

Laurent

Well,if the tone is detected,it is detected,so it has nothing to do with load.i guess the event is not fired because playcollect does not thinks it should be fired.therefore i would reccomend to check bigger wireshark dump and check all the mgcp traffic for endpoint + add more logging for dtmf processing on play collect to understand better why it hapens

Hello,

I have done more test and finally I can reproduce the bug on my test server.

when I have 2 calls connected, if the call A send a DTMF and just after the call B send also a DTMF then the second DTMF is not notified.

I have added lot of log to understand how the different listener are connected together
and I see that the flag isActive in Event object (DTMF event) of the second call is set to False, so they is no notification ...

public void fire(Signal s, Text options) {
        System.out.println("LSR | Event | fire ");
        if (this.isActive) {
            System.out.println("LSR | Event | is active ");
            System.out.println("LSR | Event | " + requestedAction.getClass().getName());
            this.requestedAction.perform(s, this, options);
        }
        else
        {
        System.out.println("LSR | Event | is NOT active ");
        }
    }

actually I don't know when/why this flag is set to False.

I have attached a wireshark trace, maybe you will see what I’m doing wrong..

I just see that if I remove the ES of the call A then it's ok ....

Hello,

After different test I saw that dtmf signal event (0,1,2 … C,D,*,#) are only created for the first IVR endpoint (see log below).

So when I send the End Signal Event just after I get the first DTMF event, all DTMF Event are rested and the isActive status is set to False until a new IVR is initialized and this not only for the call that has send the DTMF event but for both.

Hi
Try to remove static for all tones classes
For example for dtmf 8 remove static near dmtf_8 object definition:
https://code.google.com/p/sipme-media-server/source/browse/controls/mgcp/src/main/java/ua/mobius/media/server/mgcp/pkg/dtmf/Dtmf8.java?r=6608c40637d5a9a6cf24f89f3024aba95a5302a6#38

Same for all tones.
Best regards
Yulian Oifa
