[asterisk-users] Zaptel/mISDN and call transfer

You can run chan_capi on top of mISDN, but I have never done this myself 
(be careful to not confuse mISDN with chan_misdn). Anyway, I am not sure 
what "mISDN hardware" would be, whereas "CAPI hardware" would refer to 
cards that come along with a CAPI interface/driver like Eicon Diva or 
various AVM products, possibly also HST products.

Or Sangoma (which uses zaptel), or Sirrix (comes with its own channel 
driver). My personal suggestion would be that you take a closer look at 
Eicon and Sangoma.

That won't work.

By the way, you might want to also search for "call deflection" (CD) and 
"partial reroute" (for PtP = point-to-point connections = 
"Anlagenanschluss") next to ECT. See:
