Additional Configurations for the Cisco Unified SIP
Phone 3911
Depending on your network configuration and topology, you may need configure
the Cisco Unified SIP Phone 3911 on the Cisco Unified Communications
Manager to include the following:
•
Configuring a SIP Phone Dial Plan, page 4-9
•
Enabling the Cisco Unified SIP Phone 3911 to Use DTMF, page 4-9
Configuring a SIP Phone Dial Plan
Key Press Markup Language (KPML) allows for the digits to be sent to Cisco
Unified Communications Manager digit by digit. Cisco Unified Communications
Manager defaults to the use (KPML) when SIP dial rules are not configured. SIP
Dial Rules allow for a pattern of digits to be collected locally on the phone prior
to sending to Cisco Unified Communications Manager. Cisco Unified SIP Phone
3911 does not support KPML. To ensure successful call completion, you must use
the 7940_7960_OTHER dial rules pattern to configure a SIP phone dial plan and
to associate the plan with the Cisco Unified SIP Phone 3911.
Enabling the Cisco Unified SIP Phone 3911 to Use DTMF
To access voice-messaging systems or to navigate interactive voice response
(IVR) applications from Cisco Unified SIP Phone 3911, you must have one of the
following configurations on your system:
•
Verify that you have a transcoding device that supports RFC 2833 on your
system and that the trunk that is going to the transcoder is configured for MTP
by using Cisco Unified Communications Manager Administration.
•
On Cisco Unified Communications Manager Administration, check the
Require DTMF Reception checkbox for each registered Cisco Unified SIP
Phone 3911. Cisco Unified Communications Manager will verify transcoder
support for RFC 2833 and allocate its own MTP resource as necessary.
