Re: [OpenSER-Users] Off topic: generating ringback tone from audio files

Hi Guys, I also have done it and it worked like a charm. I could even queue streams (more steps), all being played inband, therefore no charge from PSTN side. It all depends on your carrier whether he (or his partners) will open one way channel on PSTN side or generate his own stuff when receiving Progress indicator on ISDN (#C7) side - even Cisco ASes have this option built in as a dial-peer command.
