Call recording with MMS

[Laurent Schweizer]

Dear all,

 

I’m using the last trunk version of MMS  and I see that sometimes I have inaudible  recorded wav message

 

I have done 3 tests from the same GW to the same MMS , no restart between record.

 

First call  is NOT OK,

Second call is OK

Third call is OK

 

I have attached all record.

 

Any Idea ?

 

Laurent

On hearing it is pcma/pcmu miss match. Say data was alaw but interpreted as ulaw.

I have tried to only use pcma  so I have commented  in /home/mms/mms-server-svn/media/io/rtp/src/main/java/org/mobicents/media/server/impl/rtp/sdp/AVProfile.java other codec

 

   static {

        audio.add(pcma);

    //    audio.add(pcmu);

    //    audio.add(speex);

  //      audio.add(gsm);

//        audio.add(g729);

        audio.add(dtmf);

    }

 

 

But I still get sometimes the same issue

 

Any idea ?

It is a format mismatch between recorder and spliter so A/V profile modification will not fix this issue. Actually it happens to miss rates and it is known issue (and several others which potentialy exist) and I can fix it only in next release in a batch.

Hi Laurent ,
Can you check if the issue persist with 2.2.0 CR2
It can be downloaded from here :
http://code.google.com/p/mediaserver/downloads/list

Yulian Oifa

[Laurent Schweizer]

Hello,

I will do the test tomorrow and send you a feedback.

Hello all,

I have done the test with this version and I have sometimes the same issue.

I have also see another problem, after some time (I see it after running 1
day) the file is completely not usable I mean we cannot open them with
windows media player, I have attached an example. I have restarted MMS and
was again ok.

Regards

Laurent

Hi Laurent ,

[yulian_o]

Hi Laurent
I have commited new release at :
http://code.google.com/p/mediaserver/source/browse/

It optimizes a memory usage , and changed the transcoding logic
which in case can minimize an recording issues.

Please let me know if the issues persists.
If yes , especially that after some time a file is not readable please
let me know if you are using same filename for all recordings , or
using
different name each time. if its same file please try to use unique
name .

Best regards
Yulian Oifa

[Laurent Schweizer]

Thanks I will test this new version.

Regarding the filename, he is always different.

Hi Laurent

[yulian_o]

Hi
I have checked the files and its format problem.
If you will take a look at this link :
https://ccrma.stanford.edu/courses/422/projects/WaveFormat/

You will see that file should be started with RIFF(52 49 46 46)
While i am checking your files i see that they are started with 08 00

While checking recorded files that are created by jsr 309 tests i see
that file start is ok.

More then that if i paste first 44 bytes of data into begining of your
wav file
from other file , it becomes readable and can be played.

So bottom line its missing header problem.Looks like header is not
added to file and therefore
recorded file can not be readed.

I will make further inverstigations , and will post an update.
Best regards
Yulian Oifa

[Laurent Schweizer]

Thanks for the feedback

For info, I'm not using jsr 309 but MGCP.

With the 2.2.0 CR2 I don't have this error (or at least not after a
restart)

Laurent

Hi
i have modified a recorder and commited a changes
Please try to use it now.
Also please let me know if the problem exists and whether or not you
receive a warning in this case.
Best regards

[Laurent Schweizer]

Hello,

I do the test and same problem.

I also just see that the initial test that I have done with the 2.2.0-CR2
was not correct, (error in the script path ) so I have started the other
version ( SVN trunk) .

I do again the test with 2.2.0-CR2 and I see the same problem, sorry for
the wrong information

Regards

Hi

[yulian_o]

Hi Laurent
Do you receive an warning in log files (WARNING!INVALID POSITION)?
Its important to know since its either heapbuffer problem and in
this case warning should be there , or file output channel.

Best regards
Yulian Oifa

[Ivelin Ivanov]

Lauren,

Did you mean git trunk instead of SVN trunk? MMS 2.2 is hosted on git:

http://code.google.com/p/mediaserver/source/checkout

Ivelin

[Laurent Schweizer]

Hi Yulian,

No no warning.

bellow log of MMS and after MGCP trace from jain-slee to MMS

I have also attached the recorded file .

Hi I have commited a changes.

Fantastic !
Just to let you know there is a bug in FileChannel used by java.
While using write operation and then transferto operation it not
always writes both parts of data , with some kernels the first write
operation data
is discarded.
I added a force call to make sure it writes data to file , and also
changed from
transferto to transferfrom function , which allows to set the index
( position ) to which
data should be written.

Best regards

Thanks for the info,

Just a question, is that possible to retrieve the record duration with MGCP.

Actually before recording a message I play a announce (all in one MGCP
request) and as the announce can be a personal announce (so with different
duration) I cannot calculate the record duration .

So is that possible to get with MGCP the real record duration , the idea is
to not send/use record less that 1 or 2 seconds. If not I will do the record
in 2 step, one to play the announce and one to record the message.

Best regards

Laurent

Hi Laurent
The only option that exists in mgcp au packate is ap return
parameter , this way you will know how much
time was the announcement itself.
Take a look at : http://tools.ietf.org/html/rfc2897 6. Return
Parameters

But i guess it gives you nothing since it does not gives any data
about recording.

Best regards

Hi Laurent

Laurent,

Wouldn't it be wiser to split the play and record in two steps anyways, because if they are mixed, it is almost certain that you will be recording silence while the user is listening to the announcement?

Hi,

 

Yes I will split in two steps  but I think that the record is only starting after all announcement contained in the  playlist are completely played .

 

Regards

 

Laurent

This is the case. The record phase only starts after the prompt phase
has finished, in the single 'pr' call.

Thank you both for clarifying. I learned something new.

Would you be interested in sharing a simple example of your application on a blog post or the MMS wiki? Implementing these advanced IVR use cases would be of interest to a broader audience: call recording, fast forward, pattern matching...
