Connecting with legacy E1/T1 device or PBX/phone system
In the market, we still can see many legacy phone systems running. To get new features with IP communication, the device has to connect with the new IP system through E1/T1 ports. 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.
