An Essential Component of Remote Working

During the outbreak of COVID-19, the “social distancing” recommendations force most of employees of enterprises and organizations to work from home (WFH). Thanks to the latest technology, now it is easier for people to work from anywhere outside the traditional office environment. Obviously, it is not just a need for now, also for future, as more and more companies especially internet companies allow staffs work from home and work flexibly. 

How to collaborate each other from anywhere in a stable, secure and effective way?

DINSTAR SBC is an essential component which couldn’t be overlooked in remote working and work-from-home solution, ensures the connectivity, security and availability, offers a possibility to build a more stable and secure IP telephony system to help staffs collaborate even they are in different locations.

Employees working from home, or using a SIP client on their mobile phone can register through the SBC to the IP PBX, so the users can use their normal office extensions as if they were sitting in the office. SBC is providing far-end NAT traversal for the remote phones as well as enhanced security for the corporate network without the need to set up VPN tunnels. This will make the setup much easier, especially at this special time.

Network topology hiding: SBCs use network address translation (NAT) at the Open Systems Interconnection (OSI) Layer 3 Internet Protocol (IP) level and the OSI Layer 5 SIP level to keep internal network details hidden.
Voice application firewall: SBCs protect against telephony denial of service (TDoS)attacks, distributed denial of service (DDoS) attacks, fraud and theft of service, access control, and monitoring.
Encryption: SBCs encrypt the signaling and media if the traffic traverse enterprise networks and the Internet using Transport Layer Security (TLS) / Secure Real-Time Transport Protocol (SRTP).

IP trunk load balancing: SBC connects to the same destination over more than one SIP trunk group to balance call loads evenly.
Alternative routing: multiple routes to the same destination over more than one SIP trunk group to overcome overload, service unavailability.
High availability: 1+1 hardware redundancy ensure your business continuity Interoperability

Transcoding between various codecs and between different bitrates (for example, transcoding G.729 in enterprise network to G.711 on SIP service provider network). 
SIP normalization via SIP message and header manipulation. Even you are using different vendors’ SIP terminals, there won’t be compatibility issue with the help of SBC.
