Create the Device Configuration file on the provisioning server 35
— y - the corresponding primary and secondary IP addresses. y=1
indicates the primary address and y=2 indicates the secondary
address.
— port_number - the SIP proxy signaling port (default is 5060).
SERVER_RETRIES[x] [number_of_retries] confirms the number of
retries for each domain.The default number of retries is 3.
— x - the domain number from 1 to 5.
— number_of_retries - the number of retry attempts to connect to
the proxy server.
DNS_DOMAIN [domain] is the DNS domain of the IP Phone 1120E.
DEF_USERS[x] [user_name] allows you to enter the default user name
for all domains. When the device configuration file gets downloaded, the
default user name is used when logging in.
— x - the domain number from 1 to 5.
— user_name - the default user name.
UPDATE_USERS [YES | NO] affects the default user names stored in
the IP Phone 1120E. If this flag is set to YES, the default user names
are overwritten each time a new device configuration file is downloaded.
— YES - the default user names are overwritten each time a new
device configuration file is downloaded.
— NO - the default user names are not overwritten each time a new
device configuration file is downloaded.
SIP_PING [YES | NO] The SIP_PING configuration value is used to
maintain server heartbeat detection and to keep a firewall pinhole open.
When used for server heartbeat detection, the IP Phone 1120E
periodically pings the SIP Proxy and awaits a response. When three
attempts to ping the SIP Proxy fail, the IP Phone 1120E begins a failover
process and attempts to connect to the next configured SIP Proxy IP in
the same domain.
When a NAT TRAVERSAL method is selected, the SIP_PING
configuration value also helps keep a firewall pinhole open.
Decide carefully whether SIP_PING usage is appropriate for your
environment. Even when SIP_PING is not used for NAT TRAVERSAL, it
is highly likely that you must keep SIP_PING enabled for server heartbeat
detection.
