[HowTo] how-to compile chan_datacard with FREETZ for fritz!box 7170/7270

Hello,
I need to compile chan_datacard with FREETZ for fritz!box 7170/7270.
I think to asterisk 1.6.2.17 + chan_datacard (trunk if possible).
Can someone help me?
Thank you.

I don't understand if FREETZ (that I know) and OPENWRT (that I don't know) are the same or if they are different.
If they are the same, why I can't find "rules.mk" file (refered in the Makefile that you shown me in previous message) on my Ubuntu with FREETZ installed?
If they are the different, how can I download OPENWRT for Fritz!box on my Ubuntu operating system?

Well, I have compiled asterisk (1.6.2.17.2) and chan_datacard (release 54) with FREETZ (trunk).
It works pretty well.
Although I have a problem of delay in the audio signal by Fritz to the person who has been called, but no delay by the person who has been called to Fritz.
This problem RESOLVES ITSELF if you make a second call IMMEDIATELY.

I also tried chan_datacard (trunk, i.e. release 184), but with bad results.

My questions are:
1) How are the results with OpenWRT? The call is good? No delay?
2) I am interested in using OPEWRT, but I have yet to find a HOW-TO. Can you help me?

I see that the problem does not arise:
- when Asterisk is just started;
- when a call was just made by Asterisk (SIP call, without chan_datacard);
Instead, the problem occurs after the system "Asterisk-chan_datacard-K3520" remain inactive for a few minutes (at half-sleep), then the processor speed and memory speed reading are crucial to wake up the system that is sleeping.

So, I put a patch to the problem:
before making a call with chan_datacard, I wake up the system in this way:
- I make a call by chan_datacard calling the same number of SIM contained in the K3520 (so it is busy);
- Wait 15 seconds with Wait(15)
With these two steps I wake up the system "Asterisk-chan_datacard-K3520".
Finally, I make the call by chan_datacard and WORKS FINE, even if I have to wait 30 seconds to listen ringing.

It would be interesting to see who is to blame in this situation.

Ok, thanks.
Can you tell me in which thread you write, so I can follow up the issue (I translate German to English by google translate).

I have used FREETZ.

1) Go to your ubuntu computer and, from command prompt, type:
svn co http://svn.freetz.org/trunk freetz-trunk -r 7450

2) cd freetz-trunk

3) from http://freetz.org/ticket/706 download (in the directory freetz-trunk):
- asterisk_1.6.2.20_chan_capi_datacard_dongle.patch

4) apply patch, typing from command prompt:
patch -p0 < asterisk_1.6.2.20_chan_capi_datacard_dongle.patch

5) compile, typing:
make menuconfig
(in HardwareType, select 7170 or 7270)
(in FirmwareLanguage, select english or deutsch)
(in FreetzLanguage, select english or deutsch)
(in PackageSelection/Testing, select asterisk with chan_capi, chan_datacard, chan_dongle)
(in AdvancedOptions/KernerlModules/Drivers, select usbserial.ko)
make

6) new firmware image is under "images" directory

THERE IS NO DELAY NOW !!!!!!!!!!!!!!!

I use fritz!box 7170 Firmware version 29.04.82freetz-devel-7450M
and K3520 dongle with firmware 11.314.21.31.00
My dongle.conf file is empty
instead my datacard.conf is:

[general]
interval=15
language=it
;jbenable = yes
;jbforce = no
;jbmaxsize = 200
;jbresyncthreshold = 1000
;jbimpl = fixed;
;jbtargetextra = 40
;jblog = no

[datacard0]
context=datacard-incoming
audio=/dev/ttyUSB1
data=/dev/ttyUSB2
group=1
rxgain=12
txgain=2
autodeletesms=yes
resetdatacard=yes
;u2diag=0
;usecallingpres=yes
;callingpres=allowed_passed_screen
disablesms=no



in extensions.conf you can call by K3520 dongle with
exten => _X.,1,Dial(Datacard/datacard0/${EXTEN},45,tT)
exten => _X.,2,Hangup()



if you telnet your fritz!box e type "lsmod" from command prompt can you see the line
usbserial ..... 6
NOTE: the 6 at end of line is the proof that chan_datacard use usbserial module,
if you don't see it, you have to load it by typing from command prompt

insmod usbserial vendor=0x12d1 product=0x1001 (this is for K3520 stick, elsewhere you can type "insmod usbserial")



then, you can start asterisk.



HOW SMALL IS YOUR DELAY?
200-500 ms?

This is the firmware for 7170 (normal version, it is not the SL version).
You have to use a usb memory stick.

Note: after download, you have to remove ".dat" extension.

I THINK THAT YOU HAVE TO USE A K3520 STICK !
