For example, there's a range of different "voip" codecs that can do the job, some with pretty decent quality. I have been able to get a demo system with full voip 2-way audio going on a small external Cortex M4 MCU, with support for the full range of standard telephony codecs. I plan to port a subset of that to run directly on the ESP8266 for some derivative uses.
I'm interested in this module as well, any updates or have you moved on? I'm working on a commercial voip project that I'd love to have your help on, possibly as a contractor. We need two way mono audio in a pretty compact form factor, thus the ESP8266. PM me if you are still around and interested.

I'm just getting into the esp8266 world and came across your render as I was wondering if one could add an amp to aboard. Did you ever get any of the boards made? Did they work well?
Thanks, Martyn
