•
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 ser ver heartbeat detection, the IP Phone 1140E
periodically pings the SIP Proxy and awaits a response. When three
attempts to ping the SIP Proxy fail, the IP Phone 1140E 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.
ATTENTION
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.
If the IP Phone 1140E 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 Phone
1140E must be rebooted for the change to take effect.
— YES - enables pinging
— NO - disables pinging
