Question

I have been trying to get a2billing to work for the past 4 days now, i followed 4 tutorials and they all gave me some insight into how things work.. but the a2billing is still not working..

my Asterisk works fine, freepbx i can make extension and place calls on trunks, internals perfect…

I installed a2billing.. the admin,user,agents.. all that works – i can log in add rates,trunks, the simulator get the correct routes,rates and trunks..

I can make a user log in using a sip device.. but for the love of god.. every single time i dial I get error q931_disconnect_code_21

ISDN Code says–
Cause No. 21 - call rejected.
This cause indicates that the equipment sending this cause does not wish to accept this call. although it could have accepted the call because the equipment sending this cause is neither busy nor incompatible. This cause may also be generated by the network, indicating that the call was cleared due to a supplementary service constraint. The diagnostic field may contain additional information about the supplementary service and reason for rejection.

Which means the host(a2billing and asterisk) knows about the call but activbely denied routing the call.. IN the simulator i use the same number that works in there on my sip.

I am on Ubuntu 10.4LTS – Asterisk was installed using apt-get -> /usr/share/asterisk but i also have a /var/lib/asterisk

i made a ln -s to /usr/src/a2billing/AGI/a2billing.php /usr/share/asterisk/agi-bin (the asterisk conf defines this as the agi location-and freepbx time,freebpx echo works)

Another problem is that a2billing has not made 1 single log file and i cannot determine what the heck is going on(the permissions are set write global and belong to asterisk).. asterisk logs are clean.. sip, trunks are all registered.

I connect to a2billing user, place call– silence. and just error q931(zoiper on iphone) if i use the freepbx extension i can talk with anybody iusing freepbx routes.

I followed this guide
http://www.data4ict.com/tutorials/a2billing/a2billing.asp

basically i skipped freepbx out of the picture, so its just asterisk direct to a2billing.. and all the steps and verifications are just like he shows (execpt i use /usr/share/asterisk instead of /var/lib/asterisk… ??.. step by step idiot tutorial and i still cant get it working.

I set all the version to 1_6, permissions are good- i even wrote test into the a2billing_agi.log and it shows the test string on the admin end.. but never writes anything to the log file.

apache2 runs runs as www-data:www-data
asterisk runs as asterisk:asterisk
freepbx (i disabled it for now but runs as asterisk)

I made links to both var and usr agi-bin folder back to placed the a2billing.php with the lib link

my current config is like the ones in the turorial extensions,sips,iax’as

A2Billing 1.9.4 (Cuprum)

Has anybody have any suggestion how to debug what is going on. Maybe if i can jsut get the logs to work that will help.. I am really bumbed out now .. 5days later.

Or is there a ready to go a2billing distro i dont know about maybe..

Answer 1

You have a problem with the PHPAGI not connecting properly back to asterisk.

Using FreePBX will be layered out, any extensions in freepcb will not apply in A2Billing unless you use custom extension routes.

A2Billing is not very easy to setup.

Also, try to debug Asterisk by typing in the console

asterisk -rvvvvvvvvvvvvvvv

And read what it logs back to screen, all the v set it to the higherst verbosity level, so it will tell you everything that happens step by step

Good Luck
