If it says just G711 then it can do both ulaw and alaw. Also, if we are not using the PVDM3-32 module in a shared environment, then since this is a "low complexity" use, you could probably run 32 active calls. Although most IOS versions will not let you configure "low" as a codec complexity type.

audio - Decode G711(PCM u-law) - Stack Overflow
https://stackoverflow.com/questions/3251782/decode-g711pcm-u-law
The audio is encoded in G711 (PCM ulaw). Do I need to decode the PCM audio data to a raw audio data before I could pass it to the audio engine to play? If so, is there some sample code on how to decode it? I am confused as somehow I believe PCM is already RAW. Could I just feed it directly to the audio engine on Android for example?
