In part 1 I addressed Soljon’s question about how to physically connect a G.722 capable SIP phone to a traditional audio mixer for use in an online radio project.
I understand and appreciate the intention to use a phone as the audio interface device. Phones are effectively appliances, offering excellent audio quality combined with simplicity of operation and high reliability.
This very logic leads me to use my Polycom IP650 in some unusual ways. For example, when I occasionally guest host the VUC calls I will call the ZipDX wideband conference bridge on one line, then call the Talkshoe G.711 bridge on a second line and perform an on-phone conference to connect the two bridges. Finally I engage the call recording function on the IP650 to give me an uncompressed WAV recording of the entire call.
