Hi , I have been Spending hours on this issue and can not get a successful call back. when i call in it hangs up and i get an error with the cli and with this perl callback script which i saved in paste-bin. callback_daemon-1.0.prod_r1528-py2.6.egg= http://pastebin.com/GGHUmHnq | asterisk 13 A2Billing v2.1.0 http://pastebin.com/1pkexcaM

I am using Dial-plan
Code:
[a2billing-all-callback]
exten => h,1,Hangup
exten => _X.,1,Set(CALLERID(num)=${CALLERID(num):1})
exten => _X.,n,Ringing
exten => _X.,n,Wait(2)
exten => _X.,n,DEADAGI(a2billing.php,1,all-callback,) ;last parameter is the callback area code
exten => _X.,n,Hangup


i also have a2billing callback using his context but i have also tried the default which was a2billing-callback with the same results.

Thanks,
Allen

The main thing is the Daemon dies after trying to run the callback in the queue...

Hi,

Looks like i have came across right place.

I am using same versions and getting exact same issues.
So i updated python to 2.7 as mentioned in previous reply of yours.

But then its throwing another issues when we start callback daemon.

Quote:
[[email protected] callback_daemon-1.0.prod-r1528]# /etc/init.d/a2b-callback-daemon restart
Stopping a2b-callback-daemon: [FAILED]

ImportError: No module named callback_daemon.a2b_callback_daemon
Starting a2b-callback-daemon: [FAILED]


Any solutions?

Please let me know.

Version info:
Quote:
OS: CentOS release 6.6 (Final)
Asterisk 13.3.2
A2Billing v2.1.0




Thanks,
Arpit

not a pro at python, but i had made an install for both pythons to run side by side and installed by source..

i changed the bash in the scripts to use python2.7 and after python2.7 was installed i had to re follow the initial instructions
i used easy_install2.7 to install sqlalchemy & psycopg2
- cd /usr/local/src/a2billing/CallBack
- easy_install callback-daemon-py/dist/callback_daemon-1.0.prod_r1527-py2.5.egg

For RedHat :
- cp a2b-callback-daemon.rc /etc/init.d/a2b-callback-daemon
- chmod +x /etc/init.d/a2b-callback-daemon
For RedHat :
- chkconfig --add a2b-callback-daemon
- service a2b-callback-daemon start
- chkconfig a2b-callback-daemon on


if your system has both versions of python then u need to make sure all is using the correct python and install its depenacies under the correct version..
if your system only has 1 version i would just start at the beginning o the instructions

Hi,

Thanks for your response.

Yes, i reinstalled everything after installing python 2.7

I am able to do easy_install of callback_daemon-1.0.prod_r1528-py2.7.egg but older does not work.

If we keep same old python 2.6.6 and follow instructions mentioned below then its getting same issue which you faced.

Callback installation steps
Quote:
LOAD_LOC=/usr/src/a2billing
yum -y install python-setuptools.noarch
yum -y install MySQL-python
easy_install sqlalchemy
cd $LOAD_LOC/CallBack/callback-daemon-py
cp callback_daemon/a2b-callback-daemon.rc /etc/init.d/a2b-callback-daemon
chmod +x /etc/init.d/a2b-callback-daemon
cp dist/callback_daemon-1.0.prod-r1528.tar.gz /tmp
cd /tmp
tar xvfz callback_daemon-1.0.prod-r1528.tar.gz
cd callback_daemon-1.0.prod-r1528
python setup.py build
python setup.py bdist_egg
easy_install dist/callback_daemon-1.0.prod_r1528-py2.6.egg
chkconfig --add a2b-callback-daemon
service a2b-callback-daemon start
chkconfig a2b-callback-daemon on



callback service is starting, but when there is a callback entry and call is made then its crashing after first call and then we need to manually start it again.

Hi,

Can anyone please share some hints or ideas on this?
How do we make callback work?

Is there any issue with latest version of A2Billing related to callback or is it OS related issue?

Please let me know.


Thanks,
Arpit

Just if anyone face same issue:

I changed OS to Ubuntu 12.04 LTS and callback worked fine.
