Key Press Markup Language (KPML) allows for the digits to be sent to Cisco
Unified CallManager digit by digit. Cisco Unified CallManager 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
CallManager. Cisco SIP phone 3951 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
SIP phone 3951.
To access voice-messaging systems or to navigate interactive voice response
(IVR) applications from Cisco Unified SIP phone 3951, 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. Configure the trunk that is going to the transcoder is configured for
MTP by using Cisco Unified CallManager Administration.
• On Cisco Unified CallManager Administration, check the Require DTMF
Reception checkbox for each registered Cisco Unified SIP Phone 3951. Cisco
Unified CallManager will verify transcoder support for RFC 2833 and
allocate its own MTP resource as necessary.
