Most of the trunk settings will be given by the service provider, settings that are not mentioned by the provider you may leave them
blank or use default values.
 Enable : The trunk will be active and usable only if it’s enabled.
 Authentication : If the service provider doesn't require a username and password for this account to register to their server then
you can disable this option.
 Server Address : The SIP server domain or IP address.
 User Name
: Username provided by SIP Provider.
 AuthUser : AuthUser is the optional authorization user for the SIP server.
 Password : Password provided by SIP Provider.
 Contact : Contact user to use in an outbound call request through this trunk.
 Retry Interval : Once registration expired, retry interval is the number of seconds system will wait before attempting to send
another register request to the server.
 Identify By : Identify by the user name and domain or the Authorization username.
 Type : In practical applications, client mode SIP trunks are the most commonly used to connect to the SIP providers for low cost,
long distance and international phone calls, while server mode is only used when users want to do SIP trunking between IPPBXs.
 Registration Expiration : Expiration time of registration in seconds.
 Max Retry
