I have no problems with use of JMF with JTAPI. You need to use a CTI Port to transmit your files into a call. When you register CTI Port you specify a port where you will receive RTP traffic for an active call. Connect CTI Port to Cisco Call and you will receive a CiscoRTPOutputStarted event that will inform you about port and ip address where you need to transmit your file. But i need to warn you that JMF is very buggy. And sometimes you need to find a JMF sources and corrent them yourself (or write your own plgins for it). But, i am working with JTAPI and JMF about two years and still don't find better solution than JMF. All other solutions is more worse.

With my personal experience as developer, I wouldnt suggest JMF. In my opinion, JMF is ok if you are writing a client application(like a soft phone) and would be handling one or few streams at any time.
I have burnt my hands trying out JMF with server side applications trying to handle multiple streams and JMF wasnt any good with that. After a certain call load(it wasnt too huge), rtp streams started breaking up. I didnt fight too much trying to fit JMF into my solution after initial test results but it could be that I wasnt doing it right but there was very little help available to me. It was hard to find any documentation or support on JMF, most of the support and document links on Oracle website are broken and its hard to move in right direction even if you know how basic processor works with streams.
Moreover, there hasnt been any work done on JMF by Sun (and oracle now) since its last release in 2001 which was more than 10 years ago. So, it seems like an abaondoned initiative.
 
Coming to the problem as such, I have had trouble finding a robust media library/server based on JAVA so as lot of others, I had exact same question on what to use for Media streaming which can actually be seen in one of the other posts on forum. The best answer I got was writing your own RTP stack based on RFC which is what was done by one of the application developer who had responded to my post. I am myself still trying to find if ther are any better alternatives(java based) available to JMF.

Hi Sergei,

In my scenario , below are the sequence of events that needs to take place.

1. Place a call to "A".
2. After the call is connected( A picks up), send an audio file to him asking him to press "1".
3. Once he presses "1", connect a call to B.
4. Put A and B into conference.


While we are able to implement the part 1 and 4 of our scenario , we are stuck at 2 and 3. Can you please help us with the snippet if yours where you are using JMF to send the audio file to a connected party. That will really solve our problem.

Hi Sergei/Abhishek,

Can you guys please help me out with some code snippet of yours where you are using JMF . That will really help me get going with the project.

Hi Sergei,

I already implemented the transmiting of a sound file to the ctiport, but i can't ear any sound on the ctioport, but if i use JMFStudio and open a rtp session to the ip and port of the ctiport, i can ear the sound. I tried almost all CiscoMediaCapability on ctiport registration, but no success, what i´m doing wrong?

Code of ctiport registration:
....
CiscoMediaTerminal cmterm = provider.getMediaTerminal(ctiport);
CiscoMediaCapability[] caps = new CiscoMediaCapability[]{
CiscoMediaCapability.G711_64K_30_MILLISECONDS
};
cmterm.register(inetaddr, portInt, caps);
....

Code of JMF to transmit sounf file to ctiport:

Format[] FORMATS = new Format[]{new AudioFormat(AudioFormat.MPEG_RTP)};
ContentDescriptor CONTENT_DESCRIPTOR = new ContentDescriptor(ContentDescriptor.RAW_RTP);

......
DataSource ds = Manager.createDataSource(new MediaLocator("file:\\c:\\a.wav"));
mediaProcessor = Manager.createRealizedProcessor(new ProcessorModel(ds, FORMATS, CONTENT_DESCRIPTOR));
mediaLocator = new MediaLocator("rtp://192.168.32.47:8500/audio"); // ip and port of ctiport
dataSink = Manager.createDataSink(mediaProcessor.getDataOutput(), mediaLocator);
mediaProcessor.start();
dataSink.open();
dataSink.start();
......


Thanks in advance

Now with RTPManager i have the following code:

...
RTPManager rtpManager = RTPManager.newInstance();
SessionAddress localAddress = new SessionAddress();
rtpManager.initialize(localAddress);
InetAddress ipAddress = InetAddress.getByName("192.168.32.47");
SessionAddress remoteAddress = new SessionAddress(ipAddress, 8500);
rtpManager.addTarget(remoteAddress);
DataSource dataOutput = Manager.createDataSource(new MediaLocator("file:\\c:\\a.wav"));
sendStream = rtpManager.createSendStream(dataOutput, 1);
mediaProcessor = Manager.createProcessor(dataOutput);
mediaProcessor.setContentDescriptor(new ContentDescriptor(ContentDescriptor.RAW_RTP));
mediaProcessor.configure();
sendStream.start();
mediaProcessor.start();
...



But the code is executed till line "sendStream = rtpManager.createSendStream(dataOutput, 1);" the code after this line isn't executed and i don't get any exception, what i'm doing wrong?
Can help me with setting the packet size, i can't find any example in the net, and i don't see how to do that..

As i sad earlier this noise happens because JMF Packetizer default packet size 480 instead of 160. You need to manipulate a packetizer controls over the processor or find a "Packetizer extends com.ibm.media.codec.audio.AudioPacketizer" sources on the net, change default packet size and reassembly yours JMF package. There is a site with most complete JMF sources, enjoy

Hi,
 
My requirement is a similar one as :
1. Place a call to  'A'
2. On 'A' answering the call, a pre-recorded message should be played and call gets disconnected
3. Next call to be connected to  'B'.
4. If 'A', does not answer within some time say 60 seconds, call should be disconnected
5. Then place a call to 'B' so on.
 
I have implemented the above using JMF integreting with JTAPI. I could implement 1,2,4 steps, but facing issues on making the next call immediately.
First call is successful for the scenario either 2 or 4 (mentioned above) but on making the call to another party, the call gets connected, it rings for a fraction of second and gets disconnected even before the call can be answered. Also, please let me know if its possible to make calls in this manner one after another for a group of numbers using JTAPI.
 
Kindly help me in resolving this issue.
 
Thanks & regards,
Halini

Can you provide the logs from the JTAPI client itself?  These are configured via jtapi.ini (you can use the jtprefs UI app, shipped with the JTAPI plugin.)  Please enable all log types at detailed level.
