SERVER_TCP_PORT[x]_[y]
[port_number]
This parameter configures the signaling TCP ports for
each proxy.
- x — the domain number.
- y — the corresponding primary or secondary IP
addresses.
y=1 indicates the primary IP address and y=2 indicates
the secondary IP address.
- port_number – the SIP proxy signaling TCP port
(default is 5060).
SERVER_TLS_PORT[x]_[y]
[port_number]
This parameter configures the signaling TLS ports for
each proxy.
- x — the domain number.
- y — the corresponding primary or secondary IP
addresses. y=1 indicates the primary IP address and
y=2 indicates the secondary IP address.
- port_number – the SIP proxy signaling TLS port
(default is 5061).
DNS_DOMAIN [domain]
This parameter is the DNS domain of the
IP Deskphone.
SIP_PING [YES | NO] This parameter is the SIP_PING configuration value is
used to maintain server heartbeat detection and to keep
a firewall pinhole open in the case of UDP signaling. For
TCP signaling. the OS keep alive is used for failover
mode.
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 NAT TRAVERSAL, it is
highly likely that you must keep SIP_PING enabled for
server heartbeat detection.
