Chapter 6 Troubleshooting and Maintenance ATA 187 Resets Unexpectedly ATA 187 Resets Unexpectedly If users report that their phones are resetting during calls or while idle on their desk, you should investigate the cause. If the network connection and Cisco Unified Communications Manager connection are stable, a Cisco Unified IP Phone should not reset on its own. Typically, a phone resets if it has problems connecting to the Ethernet network or to Cisco Unified Communications Manager.
Chapter 6 Troubleshooting and Maintenance ATA 187 Resets Unexpectedly The ATA 187 sends messages with request type 151 to renew the DHCP address leases. If the DHCP server expects messages with request type 150, the lease will be denied, forcing the ATA 187 to restart and request a new IP address from the DHCP server. Checking Static IP Address Settings If the phone has been assigned a static IP address, verify that you have entered the correct settings.
Chapter 6 Troubleshooting and Maintenance Troubleshooting ATA 187 Security Checking Power Connection In most cases, a phone will restart if it powers up by using external power but loses that connection and switches to PoE. Similarly, a phone may restart if it powers up by using PoE and then gets connected to an external power supply. Troubleshooting ATA 187 Security Table 6-1 provides troubleshooting information for the security features on the ATA 187.
