[mobicents-public] Could not use DTMF at MMS v2.0.0.CR2

[Normandes Jr]

I could not use DTMF at MMS v2.0.0.CR2.
Look my code:

public void onCreateConnectionResponse(CreateConnectionResponse event,
ActivityContextInterface aci) {
...
MgcpConnectionActivity mgcpConnectionActivity =
(MgcpConnectionActivity) aci.getActivity();
String audioFileUrl = "file:///tmp/8kalaw.wav";
EndpointIdentifier eid = event.getSpecificEndpointIdentifier();
MgcpEndpointActivity eActivity =
mgcpProvider.getEndpointActivity(eid);
play(eActivity, mgcpConnectionActivity, audioFileUrl);
}

public void play(MgcpEndpointActivity eActivity,
MgcpConnectionActivity connectionActivity, String audioFileUrl) {
EndpointIdentifier endpointID = eActivity.getEndpointIdentifier();
ConnectionIdentifier connectionID = new
ConnectionIdentifier(connectionActivity.getConnectionIdentifier());

NotificationRequest notificationRequest = new
NotificationRequest(this, endpointID,
mgcpProvider.getUniqueRequestIdentifier());
RequestedAction[] actions = new RequestedAction[]
{ RequestedAction.NotifyImmediately };
EventName[] signalRequests = null;
signalRequests = new EventName[] { new
EventName(PackageName.Announcement,
MgcpEvent.ann.withParm(audioFileUrl),connectionID) };
notificationRequest.setSignalRequests(signalRequests);
RequestedEvent[] requestedEvents = {
new RequestedEvent(new EventName(PackageName.Announcement,
MgcpEvent.oc,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Announcement,
MgcpEvent.of,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmf0,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmf1,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmf2,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmf3,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmf4,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmf5,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmf6,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmf7,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmf8,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmf9,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmfA,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmfB,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmfC,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmfD,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmfStar,connectionID), actions),
new RequestedEvent(new EventName(PackageName.Dtmf,
MgcpEvent.dtmfHash,connectionID), actions) };

notificationRequest.setRequestedEvents(requestedEvents);

notificationRequest.setTransactionHandle(mgcpProvider.getUniqueTransactionHandler());
NotifiedEntity notifiedEntity = new NotifiedEntity("localhost",
"localhost", 2727);
notificationRequest.setNotifiedEntity(notifiedEntity);
mgcpProvider.sendMgcpEvents(new JainMgcpEvent[]
{ notificationRequest });
}

Follow the MGCP stack:

What I am doing wrong?

Thanks,

Normandes Junior.

[Vladimir Ralev]

What phone do you use? Can you make a wireshark recording. Note that there is a known problem with some phones (linphone) - if the DTMF duration is shorter than 80ms it is not detected (both inband and RTP DTMF).

[Normandes Jr]

I am using SJphone for linux. The configuration for RFC 2833 is:
* Signal duration (ms): 270
* RTP payload type: 101
* Signal volume (-dBm0): 10

This message appears many times at MMS log:
WARN [JitterBuffer] Packet RTP Packet[marker=false, seq=21314,
timestamp=424160, payload_size=160, payload=8] is discarded by jitter
buffer( packet time=53020, current time 53058

Thanks,

Normandes Junior.

[Vladimir Ralev]

Same with linphone, but this one doesn'r happen regularly.

[Normandes Jr]

I can change the configuration of SJphone, what should I configure to
solve this issue?

Don't know about sj. See if there are settings for shifting the timestamps. But i guess you can also try to increase the jitter buffer in MMS to some big value. It does have some effect with linphone.

[Vladimir Ralev]

Oleg or Amit should comment on this. Last time I heard, these packets are just arriving too late for some reason.

[Normandes Jr]

I did some changes here. The message about Jitter stop, but the SBB
still not receiving the DTMF... :(

What softphone do you use?

Twinkle works fine, and older linphones (2) work too

[Normandes Jr]

With twinkle works fine. I will try with NGN, and I update here to let
you know about the results.

Thanks.

[Amit Bhayani]

can you please pass the wireshark trace.

Also is the silence suppression on? If yes can you disable it once and try?

[Oleg Kulikov]

You need to increase duration of the tone. Keep your finger on the button more time.

2010/5/8 Amit Bhayani <amit.b...@gmail.com>

[Normandes Jr]

Amit,

What part of wireshark do you want to see? How could I identify
just the RTP that has the DTMF?

At our NGN mobicents media server could not recognize all the time.

Thanks,

Normandes Junior.

[Vladimir Ralev]

The best would be a complete wireshark trace of the SIP, RTP and MGCP. But most likely just the RTP will suffice. I am pretty sure your phone sends the DTMF, but may be something is off and unexpected in MMS.

[Normandes Jr]

OK, follow the wireshark trace. (I erased some RTP parts)

I pressed the digits: 5,6,7 and 8 but at SBB I just received the digit
7.

Where should be the problem? I really need this funcionality at my
system, if it is simple to solve, please give a direction that I
compile MMS here. If I didn't solve this issue, I will have to migrate
the media server.

Thanks very much.

[Vladimir Ralev]

Well, it seems the DTMF duration is about 80ms which might not be cought by MMS. Exactly the same problem with linphone. Oleg or Amit may give you some advice if this is fixable. AFAIK they are planning on addressing this in next release anyway.

[Normandes Jr]

I hope this should be possible to fix. My boss give me a time to solve
or we really have to move out from Mobicents. :(

I don't understand the bug, because at other versions this worked, at
version 1 for example, I didn't have this kind of problem. And I can't
say to my future clients to keep their fingers at phone, and depending
of the phone, this kind of workaround is not possible.

Thanks,

Normandes Junior

[Vladimir Ralev]

OK, I debugged this issue a bit and found it is actually a silent negotiation bug. You should be able to fix it by applying this patch to media/core/servlet-impl

### Eclipse Workspace Patch 1.0

#P mms-impl

Index: src/main/java/org/mobicents/media/server/impl/AbstractSink.java

===================================================================

--- src/main/java/org/mobicents/media/server/impl/AbstractSink.java (revision 11689)

+++ src/main/java/org/mobicents/media/server/impl/AbstractSink.java (working copy)

@@ -93,6 +93,11 @@

      * @return preffered format or null if sink can not determine it

      */

     protected Format selectPreffered(Collection<Format> set) {

+     if(set != null) {

+     for(Format f : set) {

+     if(!"LINEAR".equals(f.getEncoding())) return f;

+     }

+     }

         return set != null ? set.iterator().next() : null;

     }

 

This patch is sub-optimal, but should work. Oleg and Amit can take a closer look, basically DtmfConverter is trying to find a codec that convert from linear to linear which doesn't result in anything and thus the DtmfConverter.codec is null, nothing is called. Twinkle avoids this by using speex as prefered codec by default it seems.

[Amit Bhayani]

This doesn't look like DTMFDetector problem to me but more of silence.

The wireshark trace is not giving clear idea but definitely I see some timegap between packets. Would it be possible for you to submit trace that I can open @wireshark and analyse?

One more thing to make sure that this could be silence problem, can you disable silence from your phone? If there is no way to do it, keep talking on your phone to make sure your phone sends RTP continuously 

[Vladimir Ralev]

I am almost sure it is negotiation problem. I tested a couple of different settings. DtmfConverter.codec is set to null at the time the CRCX is processed. It doesn't depend on RTP content at all, becuse codec is null from the begining. My patch just forces the negoation to find any codec wheere it is somthing to linear, instead of linear to linear. But I don't know if this causes other problems or performance issues.

[Oleg Kulikov]

Codec is null because the negotiated format is LINEAR. So no need in additional encoding/decoding of generated tone signal. Duration of tone is only one problem. We will try to handle last packets of DTMF event to generate more long signal. The problem is that ending packets have same time parameters what cause silence generation after short tone signal

2010/5/12 Vladimir Ralev <vladimi...@gmail.com>

[Vladimir Ralev]

I just retested after clean reboot and got random results, so you are probably right. Not sure why I got different result with the patch before.

[Normandes Jr]

I couldn't disable silence from my phone, so I continued talking while
press some digits. I didn't get success.

Another thing about silence, I have to change the SDP of Mobicents
Media Server to be able to complete the negotiation with my NGN, I
have to change this parameter: "a=silenceSupp:off" for this:
"a=silenceSupp:off - - - -". I don't know why, actually for me
discover this problem, I had to compare the MMS SDP with Asterisk SDP,
I saw this difference and after I changed, works fine.

Do you think that this could be a problem?

[Amit Bhayani]

This parameter just informs far end that silence should not be suppressed. Actually I didn't find any standard way (RFC) for this and found that few uses a=silenceSupp:off and asterisk uses a=silenceSupp:off - - - -

Really I don't know why there is such difference.


So with a=silenceSupp:off - - - - even DTMF detection is fine?

The wireshark trace sent by you doesn't have the MGCP traces. Looking into it

[Normandes Jr]

No, even with a=silenceSupp:off - - - - DTMF detection is not
working.

I sent to you another version of wireshark trace, now with MGCP.

Thanks a lot.

Normandes Junior.

use duration property to adjust detection (components-beans.xml)

    <bean name="dtmf.detector" class="org.mobicents.media.server.impl.resource.dtmf.DetectorFactory">

        <property name="name">dtmf.detector</property>

        <property name="duration">40</property>

    </bean>

Setting this property MMS v2 doesn't start.

Because this property is not yet exposed in DetectorFactory. Its TODO and we will make it configurable before next release

In the mean time to achieve same result can you pls change
private final static int TONE_DURATION = 50;

to

private final static int TONE_DURATION = 40;

in DetectorImpl and try.

Commited factory with configured property

2010/5/13 Amit Bhayani <amit.b...@gmail.com>

[Normandes Jr]

Not working yet. MMS v2 doesn't start.

I download http://mobicents.googlecode.com/svn/trunk/servers/media/core/server-impl
and I changed the variable private final static int TONE_DURATION to
value 40.

I complied it, and then I changed the file mms-impl-2.0.0.CR2.jar for
the mms-impl-2.0.0.CR3-SNAPSHOT.jar

MMS v2 doesn't start. Am I downloading from wrong svn path?

Path is correct. what is the error message?

[Oleg Kulikov]

You also need to synchronize with server-standalone and rebuild it too

[Normandes Jr]

OK, now I compiled from: http://mobicents.googlecode.com/svn/trunk/servers/media/core
and I got this error:

Sorry, I forgot to add the property at comp-beans.xml

I will test now.

[Normandes Jr]

I am sorry, but even with duration 40 I couldn't receive the
digits... :(

It shouldn't be hard for MMS guys to reproduce the issue. Linphone 3 and SJ phone have that problem and are available for lin/win/mac. Do these work for you? I still think it may be some negotiation problem. Chaning the codec appears to make some difference.

[Normandes Jr]

How could I choose the codec?

I would like to test with other codec instead pcma.

Disable the pcma/pcmu codecs from the list in sjphone. It is in the advanced mode settings. Preferences->Audio->Compression Settings. Similarly for linphone.

[Normandes Jr]

I would like to disable from MMS v2 and not from phone, I will test
with my NGN and I can't change the its codecs. I am testing with my
real mobile.

In MMS deploy directory edit rtp-beans.xml and comp-beans.xml. Remove all entries related to g711.

[Normandes Jr]

I added a log at class:
org.mobicents.media.server.impl.resource.dtmf.DtmfEvent at method:
public static int getId(String evt) {
logger.info(">>>>>>>>> evt: " + evt);
...

And I realized that all digits are recognized here. I think that the
problem could be related with the transmission to SLEE.

Do you have some tips at what class could I modify to force the
transmission?

Thanks,

Normandes Junior.
