7 Click the Save button.
8 Repeat steps 6 and 7 for each component you want to change.
After you complete the changes to the custom configuration, you must change the active
configuration to apply these changes to the MSC. For information on how to change the active

“Changing the MSC configuration” on page 629 .
DTMF Configuration
The DTMF configuration sets the length of the DTMF tones generated by Business
Communications Manager.
The system DTMF length may need to be adjusted because of detection errors. For example, some
cellular phone tones are closer to the short DTMF millisecond range. If a company is having
trouble with cellular phone connections, it may be necessary to change the DTMF length to 30
milliseconds.
To set the DTMF length:
1 On the navigation tree, click the Resources key and click the Media Services Card key.
2
Click the DTMF Configuration heading.
The DTMF Configuration screen appears.
3 In the DTMF length box, enter a value between 30 and 60.
This value is the length of the tone in milliseconds.
4 Press the Tab key to save your settings.
