Ooma may want to chat with some of the radio stations conducting live reads for its recent on-air commercials. At least one show host in the D.C. described the service as “good as a land line” — an undersell of a product (telo) that provides G.722 wideband with about five times the fidelity of a good PSTN call.
This writer suspects the “next step” for ooma will be to test seeding telo phone sets to radio stations for promotional purposes. Anyone figured out how to put a G.722 phone call directly on the radio?
Sure — we have a big radio station in San Francisco using ZipDX numerous times each day to do live remotes.
How do they put wideband “into” the radio? Or do they downconvert to PSTN?
The whole idea is to keep the audio in better-than-PSTN fidelity, so we don’t want to down-convert.
At the studio, we interface to the SIP phone’s headset jack, and route that into the station’s audio mixing facilities.
The remote reporter’s voice is heard by radio listeners in wideband. And the reporter hears IFB (interruptible feedback) from the studio.
