SIP Dial Rule Configuration Settings
The administrator uses SIP dial rules configuration to configure dial plans for phones that are running
SIP and associate them with the following phones that are running SIP:
• Cisco Unified IP Phone 7911, 7941, 7961, 7970, and 7971. These phones use the
7940_7960_OTHER dial rules patterns. Key Press Markup Language (KPML) allows the digits to
be sent to Cisco Unified Communications Manager digit by digit; SIP Dial Rules allow a pattern of
digits to be collected locally on the phone prior to sending to Cisco Unified Communications
Manager. If SIP dial rules are not configured, KPML gets used. To increase the performance of
Cisco Unified Communications Manager (increasing the number of calls that get processed), Cisco
recommends that administrators configure SIP dial rules.
• Cisco Unified IP Phone 7940 and 7960. These phones use the 7940_7960_OTHER dial rules
patterns and do not support KPML. If the administrator does not configure a SIP dial plan for these
phones, the user must press the Dial softkey or wait a specified time before digits are sent to Cisco
Unified Communications Manager for processing. This extra step for the user delays the actual call
from being processed.
• Cisco Unified IP Phone 7905 and 7912. These phones use the 7905_7912 dial rules patterns and do
not support KPML. If the administrator does not configure a SIP dial plan for these phones, the user
must press the Dial softkey or wait a specified time before digits are sent to Cisco Unified
Communications Manager for processing. This extra step for the user delays the actual call from
being processed.
If the administrator does not configure a dial plan for a phone that is running SIP, the user must press
the Dial softkey unless the phone supports KPML. If the administrator configures SIP dial plans, those
dial plans must get associated with a phone that is running SIP, so the dial plans get sent to the device.
