Troubleshooting IP Phone Registration
To troubleshoot IP Phone Registration:
1. Record the error message on the IP Phone display, then go through
IP Phone Registration Troubleshooting.
2. If you cannot solve the problem using the IP Phone Registration
Troubleshooting Table, go through the General Troubleshooting Steps
on page 240.
Note: To rule out DHCP problems, and isolate network-related issues, we
recommend that you program the IP Phone with a static IP Address in Form
47 or from the phone itself; see page 287 for instructions.
