device when communicating with an external SIP registrar utilizing MD5 encryption. Usually this field is
populated with the PIN of the account that is used with the service provider that supports the device.
SIP Signal Port This is the port that is used for SIP communication. The default value of
this port is 5060 but can be changed is necessary to accommodate worldwide operation. Many ISP
providers may block port 5060 and to be able to operate in such environments device users may want to
change the default SIP port to another value.
Proxy IP/URL Address This is the IP Address or the Domain Name of the SIP proxy server.
Usually providers utilize Domain Name SIP proxy entry to guarantee service failover and redundancy.
Enable Registration This filed will enable or disable device registration in the defined SIP
Registrar. SIP Registration is required to allow NAT traversal and proper call authentication and routing
by service providers. In most cases this filed will be checked if the users use external providers to handle
their device traffic.
Registration TTL (sec) This is the Registration Time-To-Live (TTL) parameter in seconds. This
parameter defines how long the registration will be active and what is the period between TTL requests to
the SIP Registrar. It is also used to ensure that the NAT traversal port is open to be able to accept inbound
calls. The default value of this field is:60
Allow Calls w/o Registration. This filed will allow calls without registration in a Peer-to-Peer scenario.
In most cases registration is required if the device is services by service providers.
Outbound Proxy IP/URL Address This is the IP Address or the Domain Name of the Outbound SIP
proxy server. Usually providers utilize Domain Name SIP proxy entry to guarantee service failover and
redundancy. The SIP standard for the Outbound SIP Proxy server and the SIP Proxy server to be different
servers.
Enable Auto Discovery Tornado M53/M55/M70/M60/M80 supports Patent-Pending SIP Auto
Discovery via LAN broadcasts to find out other devices that are located within its network. This
functionality is extremely useful to identify and setup device infrastructures without the use of external
SIP proxy servers. It is commonly used in business offices where devices are located within the same VPN
or LAN. Enabling Auto Discovery will make the device aware of other devices and make itself known to
other devices.
Auto Discovery Period (sec) This is the period in seconds that is used by the device to make LAN or
VPN broadcasts making itself known and requesting information about other devices. This is part of the
Patent-Pending SIP Auto Discovery protocol that the company has developer.
Encrypt SIP Messages This option will allow encryption of SIP messages. The encryption is
proprietary and is supported by SIP Proxy, SIP Registrar, and Gateways manufactured by Sysmaster.
