VoIP Telephone Survivability Design
Enterprises are constantly deploying IP telephony. Once an enterprise makes the decision to incorporate a VoIP network deployment, a critical issue to consider is the survivability and high availability of external and internal company telephony communication system.
This issue becomes more crucial due to the IP network’s heavy task and the compatible to legacy PSTN network. When power was lost or internet was disconnected, every IT managers will face a big challenge for the telephone system’s survivability. Siptang VoIP/PSTN intelligent routing technology answers those challenges.
In regular network situations, this technology will keep work as a sip terminal. It keep detect the network connection, when the sip server is out of work, it will take up the backup mission. When the internet is broken or the sip server is down, it can detect them out. Even in the worst case, the power is lost, the PSTN intelligent routing tech will forward all out boundary calls to PSTN lines. PSTN lines will not be affected by the terminal’s power issues.
How to make the system to be compatible to the legacy PSTN network? The PSTN intelligent routing technology will take over the old phone number routing policy and redistribute those calls under whole network system’s requirement. It is very important to let the end users don’t feel any change to the number dial style.
The following diagram shows when VoIP is broken, the telephone system is still alive for all calls are forwarded to the PSTN line.
SHANG308 is the gateway which has intelligent routing technology. It connects the PSTN and VoIP network and can route the traffic automatically. SHANG308 is an ideal for corporate business as it facilitates a gradually and risk-free transition to IP telephony. Enterprises can also benefit from a variety of valuable applications such as PBX extension, remote office connectivity, long distance consolidation and call centers.
