unfortunately libssl that ships with Fedora9 is lacking a few functionalities that libsofia needs. You can however install the libsofia-sip package for Fedora 9 (1.12.8) and compile your vdk application against that one (please take care not to have both libsofia, from F9 and VDK package in you library path). It should work but I cannot assure evetything will be fine since all testing of VDK is done against libsofia 1.12.9 (that introduced more than one bug-fix).

Please note also that Fedora 9 ships with Qt 4.3.4 and VDK needs at least Qt 4.5.x so be sure that the provided ones are in your path before Fedora ones.

and i cp libssl.so.0.9.8 ,libcrypto.so.0.9.8 to the VDK directory ,rebuild the tutorial 1 ,problem again ...

what's wrong ?

regards

you have to add the following switch to your Makefile

-L/home/tntneo/vdk

or, if you are using the Qt tool qmake, you need to add in your .pro file the entry

LIBPATH+=/home/tntneo/vdk

Hope this helps

libjthread-1.2.1.so is one of the dependencies of VDK, you should have got a copy of that in the same directory where VDK was installed. You should instruct your compiler to look in that directory for VDK libraries, try the following command before launching your application:

export LD_LIBRARY_PATH="/home/tntneo/vdk"

and then try again to run you application.

when i want to build the example i got tihs warning message

/usr/bin/ld: warning: libjthread-1.2.1.so, needed by /home/tntneo/vdk/libvdk.so, not found (try using -rpath or -rpath-link)

can you help me to solve the problem
i'm on qt4.5.0 et ubuntu 9.04

it is indeed a high priority on our roadmap to provide a vdk version that is compatible with QtCreator on windows!

Unfortunately, what is holding us back still is that a 3rd party library vdk depends on is not compatible with the mingw 5.x compiler used by QtCreator. Vdk code is already compatible with mingw, so, as soon as this problem will be resolved we'll make available a package compatible with QtCreator.

best regards

VDK is able to handle multiple calls at the same time, either putting them in conference or handling one at a time. The trial version can handle just one call, that is, if you are busy in a conversation you cannot receive any other incoming call nor start another one.

VDK's VirtuaDev technology handles the connection between media sources; incoming audio of a SIP call is a device, speakers another one, wav files another and so on. To write a softphone for example you have to connect microphone to network line and network line to speakers, that is a total of two concurrent VirtuaDev connections. Again, if you want to play an audio file you need to connect the file device to the speakers, that will cost you just one connection. In the trial version the amount of available VirtuaDev connections is 4.

Hope this helps,

regards

• Only one VoIP call at once can be handled
• The number of devices that can be connected at a time is limited to 4

Can you elaborate further? Pardon me because i am still new with this but i want to learn. Thanks.

the tasks you mentioned can be very easily implemented using VDK, at the moment you can try out the trial version which is downloadable from this website.

The simple tutorial that is available within the documentation should help you to get a grip on how to do what you need, there are described exactly the steps you mentioned.

Unfortunately only c++ language is supported at the moment. In a few weeks time we will provide Java and .Net interface modules and we're working on a native PHP interface but we cannot give you an estimate delivery time for that at this moment.

Please come back to this forum if you need further assistance.

I'm working as S/W developer. Mostly developing in php, javascript etc etc.

Recently I was given  a project to work with VoIP, which is first time I'm even aware of software like this. I was suggest  to go for VDK.

Here's the brief note of what I was told to do:

1.Register and have an account with SIP

2.Outgoing call

3.terminate the established call.

Will I be able to do this with VDK?

If YES, apart from VDK s/w what else I need to run the script and how to run.

I'm total newbie so any help would be appreciated.

Thanks

Rachel

Thanks for your help!
