Call scenarios
Common call scenarios for this CDP option are listed in “Call scenarios” on
page 194 . The following additional call scenarios are unique to this CDP
option:
• Normal Mode: An SRG analog phone calls an SRG IP Phone and a main
office IP Phone registered to the main office
.
In this scenario, the telephone registered to the SRG can either dial the
SRG DN or the main office DN for the SRG IP Phone. In Local Mode,
the SRG IP telephone is reached only with the SRG DN.
In Normal Mode, the display on the IP Phone displays the main office
DN (3xxx) for the IP Phone. In Local Mode, the SRG DN (4xxx) is
displayed.
Figure 73 on page 214 shows this scenario.
