I am trying to upgrade IPP5.3 to 7.1 . I need to add "speech.lib" and I tried to compile IPP7.1 samples and create all speech related .lib files and add them. (I didn't find any specific speech.lib file.) I also add the .lib files available with speech-codecs. Code is compiled successfully but at run time I am facing this problem. * * *Error in VoIP Initialize. Error: System.ServiceModel.CommunicationObjectAbortedException: The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it has been Aborted.* * * Any help is grateful . Thanks in Advance. Deepak -- -------------- next part -------------- An HTML attachment was scrubbed...
