Why does my Cisco Adapter ATA 187 reset unexpectedly?
- BBryan JonesJul 26, 2025
If your Cisco Adapter ATA 187 resets unexpectedly, verify that the Ethernet connection is stable. Check if the port or switch the phone is connected to is down or rebooting. Ensure the phone is properly configured for DHCP, and the DHCP lease duration is set appropriately (Cisco suggests 8 days). If using a static IP, verify the settings. If resets occur during heavy network usage, configure a voice VLAN. As a last resort, use the IVR to reset the phone settings to default.
