Information About Setting Up Cisco Unified IP Phones
Cisco Unified IP Phone configuration is limited for Cisco Unified SRST because IP phones retain nearly
all Cisco Unified CallManager settings during Cisco Unified CallManager fallback. You can configure
the date format, time format, language, and system messages that appear on Cisco Unified IP Phones
during Cisco Unified CallManager fallback. All four of these settings have defaults, and the available
language options depend on the IP phones and Cisco Unified CallManager version in use. Also available
for configuration is a secondary dial tone, which can be generated when a phone user dials a predefined
PSTN access prefix and can be terminated when additional digits are dialed. Dual-line phone
configuration is required for dual-line phone operation during Cisco Unified CallManager fallback.
