Description:Asterisk and zaptel do not allow a card to handle HDLC for ISDN D channel, but zaptel does it itself. It would be more efficient if zaptel allowed cards to handle HDLC because that would reduce the central processor load.

You should consider placing a bounty for that one.

sangoma cards handle the HDLC onboard I think.

Are you aware if it is even possible for Digium cards to handle HDLC onboard?

Actually, if the board handled the HDLC, wouldn't that make hybrid voice-and-data PRIs impossible?

If someone has a need for this, they can write the code to handle it.  At that point, it can be submitted here.  Until then, it is completely pointless to leave this open.
