•

A fast-busy tone indicates that the number you called is not valid or that
external circuits are busy. Verify the number or try your call again later.

•

If you place a call to another IP telephone, hear ringback, and the called party
answers but you cannot hear the speaker’s voice, verify that the
Cisco IP Phone and the other IP telephone support at least one common audio
codec (G.711 A-law, G.711 u-law, or G.729a).

•

If you use a Cisco PIX firewall, make sure that it is version 5 or later.

Resolving Problems

This section describes errors or unexpected results that you may encounter with
the Cisco IP Phone models 7905G and 7912G. It includes possible causes and
recommended actions, where appropriate.

Symptom

Parameters with values set through a phone’s web interface or LCD

screen revert to their original settings.

Possible Cause

You are using TFTP for configuring the phone (the UseTFTP

parameter is set to 1). Parameter values in a profile will overwrite values that
you set from a phone’s Network Configuration menu, its SIP Configuration
menu, or its web page.

Recommended Action

If you are using TFTP to configure phones, do not use

the web page or the phone menus to modify SIP or network parameter values.
Use the phone’s Network Configuration menu only to initially configure
phone.
