Troubleshooting Tips
If you are having trouble connecting a call and you suspect the problem is
associated with the voice port configuration, you can try to resolve the problem
by performing the following tasks:
• Ping the associated IP address to confirm connectivity. If you cannot ping the
destination, refer to the Network Protocols Configuration Guide, Part 1 for
Cisco IOS Release 12.0 T.
• Use the show voice-port command to make sure that the port is enabled. If
the port is offline, use the no shutdown command.
• If you have configured E&M interfaces, make sure that the values pertaining
to your specific PBX setup, such as timing and type, are correct.
• Make sure the VICs are correctly installed. For more information, refer to the
Cisco WAN Interface Cards Hardware Installation Guide.
Fine-Tune E&M Voice Ports
In most cases, the default values for voice port tuning commands are sufficient.
Depending on the specifics of your particular network, you might need to adjust
voice parameters involving timing, input gain, and output attenuation for E&M
voice ports. Collectively, these commands are referred to as voice port tuning
commands.
If you need to change the default tuning configuration for E&M voice ports, use
the commands shown in Table 6-6, beginning in privileged EXEC mode:
