How to Develop a Non-stop Voice Service?
The interruption of non-stop voice service is often a concern of the employees because interrupted service may cause the company to suffer
from business losses and a bad reputation. With the dual WAN design of the ISG50, the company can connect up to two ISPs via Ethernet or
PPPoE connections to avoid VoIP service breakdowns. In addition, the ISG50 not only offers voice services through the ITSP by a SIP trunk, but
also via a PSTN/ISDN connection to ensure continuous voice services. Furthermore, in case where the WAN IP address is dynamic, the SIP
server address can be automatically updated with the DDNS function so that the mobile clients can register with the ISG50 using the domain
name.
