Carry audio via IP?

Hi all! I'm trying to use IP as link to broadcast audio. Not music only voice audio so is less complex. I work a lot with IP phones and some other audio codec as GSM and SPEEX. But now i want to do but using hardware and not a computer. What i remember is that the more simple way to digitalize voice is using G.711 codec. (u-law)

And i remember that Motorola have some chips that comes in some telecom carrier equipment. This is the MC145540 this is a ADPCM Codec. This device can be controlled via SPI and get me the ADPCM input/output in two IC pins.

Because i don't have any experience using this processors and i read some topics about VOIP in the forum i posted this so maybe is helpfully to others.

Best Regards Frank
