iii) a) Go offline then online from the 3Com Desktop Communicator presence options to force the re-
registration of the client with the VCX server.

or

iii) b) Shutdown the 3Com Desktop Communicator client and restart the application.

This will cause the client to now function as the Outlook Edition.

Additional dial rule information

1. If “( )” are used, there is a leading “+” followed by the Country Code needed.
2. If local dialing is always long distance formatted, then “99999” need to be entered as Area Code in
the Regional Specific Settings (NOT empty or other number!).

Dialing in ITU format

Numbers will be formatted in ITU standard (+<Country Code><Area Code><Number>) according to
the values entered within the Regional Specific Settings of the 3Com Desktop Communicator when
using a “+” in front of the phone number.
If number starts with “+”, the 3Com Desktop Communicator will dial Outbound Line , International
Prefix or Long Distance Prefix entered in the Regional Specific Settings (when user has not already
entered them manually) followed by the number. Therefore it is important to secure correct Regional
Specific Settings entries and to save phone numbers in the correct ITU format.
With a leading 0 in Area and/or Country codes within the Regional Specific Settings, calls will fail
when ITU format (leading “+”) is used. Therefore always enter Area and Country codes within the
Regional Specific Settings without a leading “0”.
