Hi, I couldn’t use a2billing properly. Is there any billing module for freepbx?
No, but it would be a good idea. A2Billing is a complex and mammothesque beast that is overkill for small systems.
If you just want to “bill” your extensions, you don’t need calling cards, callback and stuff. And, uglier, you are forced to create the extensions (oops, “SIP customers”) in A2Billing, NOT in FreePBX, which is a pain in the æßß to maintain.
For small setups, A2Billing can turn your days and nights into an endless gory nightmare.
Are you looking for very precise Billing, specifically, or just a Call History?
