User's Manual

• SERVER_PORT[x]_[y] [port_number] — configures the signaling ports for each
proxy.
- x - the domain number.
- 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_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] — the DNS domain of the IP Deskphone.
• 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 NAT 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.
