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:
