Power Outages When Using a Virtual Switchboard — What Businesses Need to Know
Reading time: 4 minutes
During the course of work and service usage, businesses will occasionally encounter unexpected incidents such as power outages or network connection issues, leading to interruptions in virtual switchboard service. This affects work quality and the professional image a business projects to its customers and partners. So what should a business do when faced with such incidents? Let’s explore the article below with OMICall.

Forwarding Calls to Another Business Location
This solution is commonly used in call center switchboards when a business encounters an incident and needs to forward all calls to another external group, particularly when the business has multiple locations. It is essential to ensure that your telephone service provider has the necessary features to implement this option.
Choosing a Reliable Provider
Sometimes a virtual switchboard system is disrupted due to issues on the provider’s end. For this reason, businesses need to select a provider that operates with stability. In addition, businesses can request that the provider design and build a system that ensures the highest possible level of continuous operation.
It can be said that a virtual switchboard system is more reliable than a traditional fixed telephone system. However, it still carries the risk of going down since the entire network runs over the internet. A loss of internet connection or a power outage will also cause the virtual switchboard to stop functioning.
When a business’s internal telephone system is interrupted due to a power outage, the business needs to have a backup power supply system such as a generator or UPS. To restore normal system operation, power must be supplied to the entire internet connection infrastructure, including:
- Modem
- Router
- Switch
- VoIP phones
- And more
In addition, you need to identify your internet service provider to avoid being affected by power outages. When an incident originates from the internet service provider, you should contact them immediately so that the system can return to normal operation.
Having a Backup Internet Service Provider
The two main factors for a virtual switchboard system to function are power and internet. Therefore, to prevent system interruptions, in addition to having a backup power supply, businesses should also have a backup internet service provider.
Voice calls over IP only require a low-latency internet connection, so any type of broadband connection can work. Businesses can use a mobile network provider as a backup ISP. All that is needed is an LTE modem that can be switched on during downtime to restore the internet connection.
Switching to a Smartphone Application
One of the great benefits of a virtual switchboard system is that businesses can receive calls anywhere, as long as the phone has an internet connection. When using a virtual switchboard service, businesses should seek support from their provider in installing the application on a smartphone. This keeps the system running continuously even in the event of a power outage.
Forwarding Calls to an External Phone Number
The virtual switchboard system has the function of forwarding incoming customer calls to a phone number outside the system, based on business needs such as after-hours situations or power outages. In this case, the business simply needs to register an outgoing number on the system along with the numbers to receive forwarded calls, and notify the virtual switchboard service provider to configure the system according to the business’s requirements.
Forwarding Calls to Voicemail
In the event that a business loses power or internet connectivity, callers can still leave messages in the business’s voicemail. Voicemail is handled entirely by the virtual switchboard service provider. Additionally, if the business has set up voicemail-to-email, voicemail messages will be delivered directly to the business’s email inbox.
