Parameter Data Precedence

As shown in Table 1: Administration Alternatives and Options for 1603SW-I SIP IP
Deskphones, you can administer a given parameter in a number of ways. The precedence, from
lowest to highest, is:
1. LLDP
2. DHCP
3. Settings file
!
Important:
Set failover parameters in the settings file and not in SM or SES.
Important:
4. Personal Profile Manager (PPM) through SM
5. Manual administration, unless the system parameter USE_DHCP is set to 1 (Get IP
Address automatically by DHCP), or backup file data obtained through PPM.
For example, if the SIP outbound proxy server address is defined to have the precedence
information so that the value retrieved from DHCP server has a lower precedence than the
value retrieved from the settings file, and the value retrieved from the settings file is higher than
the value retrieved from PPM, then the following determination occurs:
If the most recent value the telephone has is from DHCP and new server address
●
information is retrieved from the settings file, the telephone will use the new value from the
settings file.
If later on, the telephone receives a new server address value from PPM, it will not use this
●
value because PPM's precedence as a data source for the server address is lower than
the current value (which came from the settings file).
