Cisco Small Business SPA300 Series, SPA500 Series, and WIP310 IP Phone Administration Guide
• The user manually enters DTMF signals by using the dial pad.
• The user selects OK, acknowledging the transmission of the manual entry is
complete.
• The phone sends any DTMF signals defined by DTMF_string.
• The phone executes the next parameter. If there are no more parameters in
the dial string to execute, the phone exits to the main screen.
The wait does not timeout; the wait prompt window is not dismissed until user
confirms the wait prompt or the call is ended either by the user or ended by the
remote device.
DTMF_string—The DTMF signals that a user is sends to a remote device after the
call is connected. The phone cannot send signals other than valid DTMF signals.
Example
18887225555 ,,5552X2222
A speed dial entry triggers the phone to dial 18887225555. The space indicates
the end of the dial string. The phone waits 4 seconds (2 commas), and then sends
the DTMF signals 5552.
A message is displayed, prompting the user to manually dial DTMF signals. When
the user has finished dialing the DTMF signals, the user selects OK to confirm the
manual DTMF signal transmission is complete. The phone sends the DTMF
signals 2222.
Usage Guidelines
A user can transmit DTMF signals anytime, as long as the call is connected.
The length of the string, including the Xs or commas (,), that can be supported is
limited to the length of a speed-dial entry, dial screen entry, directory entry, and so
forth.
If the screen displayed is not a call appearance screen and a wait is initiated, the
phone displays the home screen and prompts the user to input more DTMF
signals. If this occurs while the user is editing an entry, the edits might be lost.
