Troubleshooting and Maintenance

Voice VLAN Setup Errors

Problem

If the Cisco Unified IP Phone appears to reset during heavy network usage (for example, following extensive

web surfing on a computer connected to same switch as phone), it is likely that you do not have a voice VLAN

configured.

Isolating the phones on a separate auxiliary VLAN increases the quality of the voice traffic.

Phones Have Not Been Intentionally Reset

If you are not the only administrator with access to Cisco Unified Communications Manager, you should

verify that no one else has intentionally reset the phones.
