What can I do when my Snom C520 doesn’t ring
Q: What can I do when my Snom C520 doesn’t ring when there’s an incoming call?
A: You can try the suggestions below:
- Make sure there is a dial tone before dialing.
- Make sure the ringer volume of the phone is not set to off
- Make sure the DC power cable, Ethernet cable, AC power cord, and the power adapter are plugged in properly
- If other telephones in your office are having the same problem, the problem is in the wiring or IP PBX service. Contact your service provider (charges may apply) or system administrator.
- Other electronic products such as ham radios and other DECT phones can cause interference with your conference phone. Try installing your conference phone as far away as possible from these types of electronic devices.
- Unplug the AC power cord from the wall outlet. Wait for approximately 15 seconds, and then plug it back in. If you still cannot get a dial tone, please contact our customer service hotline designated above for assistance.
- See the user manual for more information
