IP address and settings reuse

After a successful registration with a call server, the IP address of the deskphone and the parameter
values are saved in the non-volatile memory of the deskphone. The deskphone can reuse the saved
parameters if the DHCP or HTTP/HTTPS server is not available for any reason after the deskphone
restarts.
IP Address reuse was added to prevent infinite looping when separate DHCP servers are used for
voice and data VLANs, and a response is received from the DHCP server on the data VLAN, but not
on the voice VLAN.
Unless indicated otherwise, the values described here during IP address reuse are internally
provisioned or set by the process itself and not by manual administration.
• Routers in Use - if no responses are received from the routers indicated in the configuration
parameter ROUTER (set using DHCP Option 3 or by a local administrative procedure), and if
REUSE = 1, then ROUTER_IN_USE will be set to REUSE_ROUTER_IN_USE. With the
exception of the ROUTER configuration parameter, the other router-related parameters are
internally set system values.
• VLAN Check - During the VLAN check, if a reset is to be done and VLAN_IN_USE is not zero,
VLAN_IN_USE will be added to VLANLIST if it is not already on VLANLIST.
The VLAN detection process described in Automatically detecting a VLAN on page 52 is
followed if tagging is off or if tagging is on and L2QVLAN is > 0, and if REUSETIME > 0, and if
REUSE_IPADD is not "0.0.0.0". If VLANTEST expires, the value of VLAN_IN_USE is added to
VLANLIST if it is not already on VLANLIST.
If a DHCPOFFER is not received within REUSETIME seconds, or if a DHCPOFFER is received that
contains a value of L2QVLAN that is on VLANLIST, REUSE will be set to 1, IPADD will be set to the
value of REUSE_IPADD, NETMASK will be set to the value of REUSE_NETMASK, ROUTER will
be set to the value of REUSE_ROUTERS, and if the value of REUSE_TAGGING is 1, 802.1Q
tagging will be turned on with a VLAN ID equal to the value of L2QVLAN_INIT, DHCP will then enter
the "extended" REBINDING state, and operation will proceed as normal.
After a successful registration, the following system values are set:
• REUSE_IPADD will be set to the value of IPADD
• REUSE_NETMASK will be set to the value of NETMASK
