Until this point, my home voiceover studio delivered audio either via e-mail, ftp upload, or mailed CD's to clients. Recently, however, I was approached about an IVR recording job in which the client wanted me to dial into his phone patch (not ISDN) to deliver audio files directly to his in-house IVR unit.
So I've gone about researching some basic phone-patch devices and I quickly got lost in a sea of couplers, adapters, and hybrids.
I've been looking at units from JK Audio. I think what I need is a Telephone Handset Audio Tap. Essentially, I want to dial in with the handset, mute the phone, and play the audio back from my DAW's output into the phone line to my client in California. Does anyone have experience with this sort of device (or any phone patch devices for that matter) that could lend some advice?
