By connecting two ports, the device has to use NET or CPE connection with another side. The diagram shows how to connect DINSTAR E1/T1 VoIP Gateway with legacy E1/T1 to extend the phone system.

    SIP/IMS backup to fail-over with E1/T1
    Sometimes, companies use SIP for SIP calls. If in case of SIP failed, the companies have to use PSTN to make sure the call is stable and always “ON“. Digital gateways can be used as a backup or failover. If in case of SIP failed, the IPPBX still can make calls through Digital gateways.
