I have a SIP provider that gave me SIP details, when I integrate them to FreePBX direct, the inbound and outbound calls are working perfectly. However, there is no management of the call rates for users. And I have seen this can be achieved using an open source tool called ASTPP billing solutions. Has anyone here ever tried that and assist me with guideline or in case there is any open source call rates management for FreePBX is available?
Thank you.
They have all failed or lack support. If you are using this for business purposes I would either 1) Build something yourself
2) Use the supported and working Sangoma solution
It’s a paid license, but comes with support and is built specifically for the platform.
Another option would be to use A2Billing. The original project on GitHub is not maintained anymore, but there is fork maintained by @miken32 that works with FreePBX 17.
