See DAHDIAcceptR2Call() or ZapAcceptR2Call() application
CLI> core show application  DAHDIAcceptR2Call

Basically you will set in chan_dahdi.conf

mfcr2_accept_on_offer=no

This way the call will NOT be accepted immediately when the call is offered.
The call will be instead sent to the dial plan without being accepted, then
you MUST call DAHDIAcceptR2Call(yes) to accept the call with charge or
DAHDIAcceptR2Call(no) to accept without charge, you must do it BEFORE
answering the call ( that is, before doing Answer(), or before any other
application that implicitly answers the call like Playback), if you don't
accept the call explicitly with DAHDIAcceptR2Call, the call will be accepted
implicitly on answer with the default mode specified in openr2 or depending
on the specified mfcr2_charge_calls parameter in chan_dahdi.conf
