I created tcpdump package for IP04 to capture raw packets

I spend a little time to write a working dropbear ipkg mk file dropbear.mk. it is copied from asterisk.mk and adopted to dropbear.mk, here is the link:

I have been playing around the leading-edge IP PBX IP04 box a while, when it is shipped to me, it is fully working IP PBX, two FXO, two FXS. It did not satisfy my curiosity though, so I take a step further, destroyed the firmware, cross rebuild the firmware, flashed the nand, compiled the zaptel,asterisk and its ipkg package. Here is what I did:

1, svn the kernel and oslec( open source echo caneller)
svn co http://svn.rowetel.com/software/baps/trunk baps
svn co http://svn.rowetel.com/software/oslec/trunk oslec


2, enter baps directory and fetch/untar the compile toolchain
wget http://blackfin.uclinux.org/gf/download ... 386.tar.gz
.
tar xzf blackfin-toolchain-07r1.1-3.i386.tar.gz

3, edit uClinux.mk to correct "UCLINUX_SITE" link to:
http://blackfin.uclinux.org/gf/download ... e/350/3340
and make the kernel image and copy it to /tftpboot:

make -f uClinux.mk uClinux (generate uImage)
cp uClinux-dist/images/uImage /tftpboot

4, cp oslec to baps directory, edit zaptel.mk to set "ZAPTEL_EXTRA_CFLAGS" to DCONFIG_4FX_SPI_INTERFACE, then make zaptel and zaptel package

cp -r /usr/src/oslec /usr/src/baps/
make -f zaptel.mk zaptel
make -f zaptel.mk zaptel-package

5, make asterisk and asterisk package

make -f asterisk.mk asterisk
make -f asterisk.mk asterisk-package

make -f asterisk-gui.mk asterisk-gui
make -f asterisk-gui.mk asterisk-gui-package

make -f native-sounds.mk native-sounds
make -f native-sounds.mk native-sounds-package

6, create ikg snapshot and copy packages to webserver
cd ipkg
../scripts/ipkg-make-index.sh . > Packages
scp *.ipkg Packages /your/web/server


7, flash ip04 firmware

reboot ip04 and type enter while in u-boot

8, install zaptel, asterisk ipkg

change the first line in /etc/ipkg.conf on your IP04:

src snapshots http://you.web.server

root>ipkg update
root>ipkg list
asterisk - 1.4.4-1 - Asterisk PBX
asterisk-gui - 1.0-1 - asterisk-gui
native-sounds - 1.0-1 - Asterisk native sounds
oslec - 1.0-1 -
zaptel-spi - 1.4.3-1 - Zaptel
Done.
root>ipkg install zaptel-spi
root>ipkg install asterisk

9, change some part of zapata.conf and users.conf as

zapata.conf:
.....
;group=1
callgroup=1
pickupgroup=2
immediate=no

group=1
signalling = fxs_ks
channel => 1,2

group=2
signalling = fxo_ks
channel => 3,4
......

copy zapata.conf zapata.conf.post, then change /etc/init.d/zaptel to:

zapscan;
ztcfg;
cp /etc/asterisk/zapata.conf.post /etc/asterisk/zapata.conf;;

users.conf
....
[trunk_1]
....
zapchan = 1,2
....
trunkname = Ports 1,2
....
group = 1

[6001]
fullname = Analog User 1
....
zapchan = 1
context = numberplan-local
....
group = 1

[6002]
fullname = Analog User 2
....
zapchan = 2
context = numberplan-local
....
group = 1

[6003]
fullname = Analog User 3
....
zapchan = 3
context = numberplan-local
...
group = 2

[6004]
fullname = Analog User 4
....
zapchan = 4
context = numberplan-local
...
group = 2
