Nortel Networks MOBILE COMMUNICATION CLIENT 3100 사용자 설명서

How the system handles calls depends on the configuration of your 
MCC 3100 for Windows Mobile. An Outgoing Call Service DN is 
mandatory for MCC 3100 for Windows Mobile call features.

In Direct Outbound mode, initiate calls directly from your mobile device to 
other parties through the enterprise telephony system. For more 
information, see 

In Call-me-First mode, your calls are completed in two steps. First, the 
enterprise telephony system calls you. After you answer, the system calls 
the other party. See
