I've downloaded and configured my first 3CX system, added a block of 20 DIDs and have multiple phones and iPhone clients installed and configured. Inbound and outbound calls and working with clear reception on the calls. However, I configured 3 ring groups each with their own incoming DID, however all 20 numbers in my DID block are ringing to the same ring group (Main Ring Group, a custom group I created). The Main Ring Group should only be receiving calls from 3 of the DIDs, but instead any number I call in the block rings to the main ring group. Any help would be greatly appreciated.
