In the following example, a HG 3500 is used as an SIP trunking gateway. You could also use a virtual HG 3500 in an OpenScape 4000 SoftGate as an SIP trunking gateway. To do this, the AMO batch must be adapted to reflect the part number (AMO BCSU) and device type (AMO TDCSU).

This application scenario shows the connection to the SIP carrier. The service technician will use a standardized test plan with the support of system development to determine which features are possible using the respective SIP carrier.
