• UPDATE_USERS [YES | NO] — affects the default user names stored in the

IP Deskphone. If this flag is configured as 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 Deskphone periodically pings the SIP

Proxy and awaits a response. When three attempts to ping the SIP Proxy fail, the

IP Deskphone 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.

Important:

Decide carefully whether SIP_PING usage is appropriate for your environment. Even

when SIP_PING is not used for NA

T TRAVERSAL, it is highly likely that you must keep

SIP_PING enabled for server heartbeat detection.

If the IP Deskphone is behind a firewall, it is very likely that you must keep SIP_PING

enabled, unless an alternate method of keeping the firewall pinhole open is used.

The default value is YES if not specified in the device configuration file. If SIP_PING is

changed in the Device Configuration file, the IP Deskphone must be rebooted for the

change to take effect.

- YES - enables pinging

- NO - disables pinging
