Page 200 of 258 Dialing Plan configuration
553-3001-207 Standard 2.00 January 2006
Option 1: DN ranges in the main office and SRG are unique; DNs
for SRG IP Phone are the same in Normal and Local Mode
This is the recommended CDP configuration to offer seamless dialing.
In this configuration, the user dials the same DN for SRG IP Phones in either
Normal or Local Mode. The DNs for SRG IP Phones are configured to be the
same on both the SRG and main office. This allows seamless dialing from
both the SRG and main office. However, in this configuration, the DN range
for telephones registered at the SRG is unique from the DN range for
telephones registered at the main office.
The advantage of this configuration is that the system manages the routing for
the SRG IP Phones, so users in the SRG and main office do not have to be
aware of whether the SRG is in Normal Mode.
Figure 66 on page 201 shows this CDP option.
