[asterisk-dev] MFC/R2 Asterisk Channel Driver

[Denis Galvão]

There are three companies producing R2 boards in Brazil:

Digivoice: www.digivoice.com.br
Khomp: www.khomp.com.br
Pika: http://www.pikatechnologies.com

The first two companies are brazilian and have been playing with R2  
for at least a decade and both has really good and well tested  
products. I can confirm by my own.

Which of those did you tested?
