Can Sangoma A102DE support R2 for china

Hello:
My customer wants to confirm the R2 support by Asterisk+Sangoma E1 cards.
the link show that it works:
https://www.baidu.com/link?url=MhAf1dd0uAuSbDhaT5epkh7wQWVTPQX1UbM0c-TdQ-DVMXxUnPJvd-2uIdFtlTgehOLX6kCqeygOtgjlKe1gpS9EwHFJeuR6sABBFV3FzE_&wd=&eqid=c91cda7b000276420000000659fa75f0

I notice there is no any update for R2 for long time already.
Anyone from sangoma tech can give me a answer?

Thanks!
