Just wanted to brainstorm with the community because my search yielded no results. I've got a polycom soundpoint ip 600 that connects up to 3cx, can make and receive calls just fine but no ring tones are on the phone when sync'd with 3cx. I can however TFTP the device with the default 318 files from polycom and ringtones return. Yet when I register with 3cx, it loses its ringtones and dialtone. I suspect this is an issue with config files. Has anyone solved this one yet? I've tried updating the template on 3cx with no success.
