ETC with zaphfc

I’ve an Asterisk with a Digi International Datafire Micro V (a 1 BRI board with HFC-S chipset). I’ve installed bristuff-0.3.0-PRE-1l and all is working right.

I’d like to known if is it possible to make an ETC (explicit transfer call) with zaphfc.

Also, is it possible to use chan_capi on a generic boad with HFC-S chipset?

Thanks in advance
