We are using A2Billing with Asterisk PBX.
We want you to help us configure sip to sip calls for accounts in A2Billing.
You need to give us step by step guide after you have done it.
Hello,
I propose system will be installed as following:
1. OS: Centos 6
2. Asterisk
3. Frepbx
4. Fail2ban
5. A2billing
All will be setup so that you can make call via a2b. I can build a demo in case you need to check it first.
Please let me know if you have any question.
Regards,
