You need a pppd with plugin support:
kernel 2.2.X - ppp-2.3.11
kernel 2.3.99 - ppp-2.4.0b2
usage example:
Make a single call to arcor:
pppd call isdn/arcor
Make a call on demand to arcor:
pppd demand connect "" idletime 30 holdoff 1 call isdn/arcor
Make a multilink call with to channels to AVM test server:
(Only working with 2.3.99-pre8 with ppp_synctty patch)
pppd call isdn/avm-ml
pppd call isdn/avm-ml
Make a single call to arcor with outside dialing prefix "0"
pppd call isdn/arcor numberprefix 0
Make a single call to arcor using controller 2:
pppd call isdn/arcor controller 2
