Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager 8.5
OL-23092-01
Chapter 9 Troubleshooting and Maintenance
General Troubleshooting Tips
Phone call cannot be established The phone does not have a DHCP IP address, is unable to register to
Cisco Unified Communications Manager, and shows a Configuring
IP or Registering message.
Verify the following:
1. The Ethernet cable is attached.
2. The Cisco CallManager service is running on the Cisco Unified
Communications Manager server.
3. Both phones are registered to the same Cisco Unified
Communications Manager.
4. Audio server debug and capture logs are enabled for both
phones. If needed, enable Java debug.
Call established with the iLBC
protocol does not show that the
iLBC codec is being used
Call statistics display does not show iLBC as the receiver/sender
codec.
1. Check the following by using Cisco Unified Communications
Manager Administration:
–
Both phones are in the iLBC device pool.
–
The iLBC device pool is configured with the iLBC region.
–
The iLBC region is configured with the iLBC codec.
2. Capture a sniffer trace between the phone and Cisco Unified
Communications Manager and verify that SCCP messages,
OpenReceiveChannel, and StationMediaTransmit messages
have media payload type value equal to 86. If so, the problem is
with the phone; otherwise, the problem is with the Cisco
Unified Communications Manager configuration.
3. Enable audio server debug and capture logs from both phones.
If needed, enable Java debug.
