Subject: [PATCH] B410P gets incoming call packets on ISDN but Asterisk doesn't
 see the call.

The Cisco 1751 with VIC 2-BRI ports sends out SETUP messages on the
broadcast TEI as if the BRI were PTMP even though it is configured for PTP
mode.

Make PTP mode also accept frames on SAPI=0, TEI=127 (Broadcast).
