Delivering Multicast Audio on IP Phones

This post serves as a place to collect information to deliver Multicast audio on IP Phones. The testing is done on Yealink phones however we will be doing required testing on Cisco/Linksys SPA series phones as well.

To change the format and codecs of the audio, I’m using the open source tools – Audacity.

The codec and audio formatting that work is:

Codec PCM S16 LE (s16l)
Type Audio
Channels: Mono
Sample rate: 8000 Hz
Bit per sample 16
