This section allows you to configure the gateway connection to the operator more accurately.
Registar Transport - a transport protocol that will be used to transfer packets over a tcp, udp or tls network.
Realm - host name or domain name.
From user - Username (login) in the FROM field.
From domain - Domain name in the FROM field.
Outbound proxy - proxy for all outgoing connections.
CLI number - the number that will be registered in the "FROM" field of the "INVITE" message, when the internal subscriber is calling trough this gateway.
Expire - Registration time in seconds.
Codecs - The list of supported codecs.

Distinct "To" - it is used when FS requires to be registered with the help of different Address-of-Record (AOR) header «To:».
Ping - Send connection parameters every x seconds, failure will cancel the registration.
Ping max / Ping min - - the gap between ping-min and ping-max is a «safe zone». For example, if you have a minimum value - 3, maximum - 6, as a reply you receive pings 3,4,5 and 6 - the gateway is considered as active. If out of 6 packages 4 consecutive are lost, gateway is considered as unavailable.Так например, если значение минимум - 3, максимум - 6 и ответ на пинги 3,4,5 и 6 - шлюз активный. In case 4 consecutive packages out of 6 are lost, the gateway is considered unavailable.
Ping min - required quantity of successful pings to declare gateway as active.
RFC-5626 - support of RFC-5626 standard.
