There is no ability to match to an endpoint currently based on the
transport traffic comes in on. You can try enabling the line option[1]
which may allow the inbound calls to be directed to an alternative
endpoint. If this doesn't work you'll need to match all incoming to a
single endpoint and direct things appropriately in the dialplan based on
the dialed number.
