Hi all,
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.
