Summary:                    [patch] B410P gets incoming call packets on ISDN but
DAHDI doesn't generate the call in Asterisk
Description: 
Experienced on both Asterisk 1.6.2.13 and Asterisk 1.8.0, with
Asterisk-Addons 1.6.2.1, libpri 1.4 SVN 2087,
dahdi-linux-complete-2.4.0+2.4.0, compiled from source on an OpenSuse 11.3
(32 bit), kernel 2.6.34-12.

One ISDN B channel, configured as TE, with span => 0,1,0,ccs,ami, but I
tried all kinds of timing and line build type without having changes.

When I call from outside, the ISDN receives a call packet, but doesn't
generate the call in Asterisk:

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).
