How your SIP Trunking Carrier Can Manage Future Failure

Uninterrupted availability is the most significant characteristic of a SIP trunking carrier. In order to make SIP trunking even more reliable, providers need to interact with the network in order to insulate all the customer’s services from different types of system failures. In this article, we are going to take a deeper look at the ways of enhancing the reliability quotient through the addition of redundant call delivery paths to all inbound routes.

Redundancy everywhere:

Availability of SIP trunking can be assured only if there are redundant systems which would easily take over in case a primary element is impaired or lost. Geographical locations play a very significant role while locating the different processes and hardware. Power outages failed switches and lost connection to the network of other carriers can disrupt the path of calls even when your provider is completely safeguards itself from failure of their POPs. The SIP trunk providers often ignore the existing opportunities to create redundancy on their network by interpreting the regulations and optimal use of the network infrastructure.

Failover routes:

Calls cannot sop passing through in case the endpoints are down owing to a power failure or failed Internet connection. The SIP trunking carrier will be able to identify the unavailability of your system and immediately route the calls to other pre-determined backup, which can be configured at your account level. The calls will be rerouted to other locations or mobile phones, which can handle the calls until your primary call path gets restored.

The failover route need not be used frequently, but it can at least keep the work as a backup for facilitating your business operations in the event of a crisis. For instance, there are many providers who were able to carry on with their business operations after Hurricane Sandy by using the failed-over routes. Thus, it is imperative that you get the failover routes configured for SIP trunking service.

Outbound alternatives:

Just like the other technologies, infrastructure of a telephone service also faces problems. In the event of such a crisis, the well-designed systems will start sending calls to the affected routes. There are often problems when your SIP trunking reseller is dependent on a single carrier as you would be left with no other alternatives and have to wait till the services gets restored.

Changing the outgoing routes is really easy and cheaper routing depends on the ability of your systems to pick the best possible route on a real-time basis. There is no justification for the termination to get stuck due to a failed switch. You should have a quick uptime and this can be achieved only when your carrier does not rely on single point failure for all outbound traffic.

Inbound alternatives:

When your calls are delivered between you and your carrier, failover routes can get your calls through. But what happens if the call gets stuck even before reaching the carrier? All the major carriers in the world route the calls to the switches of other carriers by using the dedicated circuits. However, the contemporary scenario is such that phone calls nowadays travel through multiple carriers before it finally reaches the destination. So a snag in any of the switches somewhere will result in the calls getting stuck.

The traditional carriers need to move away from the current form of routing and have to explore various opportunities that exist in the network infrastructure – till that happens, we will have keep relying on the switches.
