I am looking to purchase a completed utility that will convert a Nortel CallPilot Audio File (VBK) to a MP3 format. At present the only method of playing these files is via the CallPilot Player (for Windows only). This play is capable of exporting files to WAV, however this is obviously not a good solution for mass-conversions or for non-Windows users.
According to Nortel the format is based on the H.232 format, however it is not the same. I can provide various samples of the VBK audio file along with their WAV conversions. I can also provide a copy of the Nortel CallPilot player for development purposes.
I would like to purchase a utility that can run at the linux command line and convert these audio files when called.
