What is a SIP Gateway Trunk?
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.
