SIP gateway trunks are used for activating gateways which are themselves reached by SwyxServer via an SIP connection. This allows e.g. telephones in small branch offices to be operated with a local gateway in each case and with a local direct connection to the PSTN. In this way, sophisticated requirements of a company network can also be met when there are numerous small sites (e.g. many shops in a chain of stores).

Generally, gateways support extensive functions for routing, firewalls, security, VPN and intrusion detection; in other words, they provide an end device for branch offices that is tailored to meet company requirements.
