Using Redial Key for “Last Number Redial”
The IP phones have an enhanced redial user interface that allows a user to quickly redial the last number that was dialed
out from the phone. You can:
• Press the Redial key twice to redial the last number dialed.
• Press the Redial key once, scroll the list of numbers, then press the Redial button again to dial the number that dis-
plays on the screen.
The “last number redial” feature for the Redial key is static and is not configurable.
Send DTMF for Remapping Conference or Redial Key
Previously, the “Conf” and “Redial” keys could be mapped to a speed dial to generate a call to a custom number when
the phone was idle. During an active call, pressing the “Redial” or “Conf” keys would put the current call on hold and
then dial the custom number. Now the “Conf” and “Redial” key remappings have the same behavior as the “Speed Dial”
key when the phone is idle. During an active call the phone will send the custom number as DTMF using the phone con-
figured DTMF method (inbound vs out-of-band RFC2833 vs SIP INFO).
This feature can be configured using the new “map redial as dtmf” and “map conf as dtmf” parameters.
When a user presses the “Redial” key, the mapped number will be sent out as DTMF during an active call if the current
“map redial key to” parameter is configured to a number and the “map redial as dtmf” parameter is set to “1”.
When a user presses the “Conf” key, the mapped number will be sent out as DTMF during an active call if the current
“map conf key to” parameter is configured to a number and “map conf as dtmf” parameter is set to “1”.
Enabling or Disabling the Sending of DTMF with Remapped Redial and Conf Keys
Use the following procedures to configure the remapping of the “Redial” and “Conf” keys on the IP phone.
Note:
You can use the Redial key during active calls.
Configuration Files
For specific parameters you can set in the configuration files, see Appendix A, the section, “Send DTMF for Remapping Conference or Redial Key” on
