Verifying Cisco Unified CallManager Settings
The Cisco Unified IP Phone attempts to open a TCP connection to all the
Cisco Unified CallManager servers that are part of the assigned
Cisco Unified CallManager group. Take one of these actions to verify
Cisco Unified CallManager settings:
•
On the Cisco Unified IP Phone 7905G or 7912G, choose Settings > SIP
Configuration and look at the SIP Proxy 1–4 options. (See
“Configuring Settings on the Cisco Unified IP Phone.”
)
•
On any phone model, display the Network Configuration area of the
Cisco Unified IP Phone web page and look at the SIP Proxy 1–4 options.
(See
Appendix A, “Reference List of Parameters.”
If none of the Cisco Unified CallManager options contain IP addresses or show
Active or Standby, the phone is not properly registered with
Cisco Unified CallManager. See the
“Registering the Phone with Cisco
Unified CallManager” section on page 7-4
for tips on resolving this problem.
Cisco Unified CallManager and TFTP Services Are Not Running
If the Cisco Unified CallManager or TFTP services are not running, phones may
not be able to start up properly. However, in such situations, it is likely that you
are experiencing a system-wide failure and that other phones and devices are
unable to start up properly.
If the Cisco Unified CallManager service is not running, all devices on the
network that rely on it to make phone calls will be affected. If the TFTP service
is not running, many devices will not be able to start up successfully.
To determine the status of a service, perform the following steps:
Procedure
Step 1
From Cisco Unified CallManager Administration, choose Cisco CallManager
Serviceability from the Navigation pull-down menu located in the upper-right
portion of the main administration screen.
Step 2
Choose Tools > Control Center—Feature Services.
