Yes, you have a few options available to you if there is a landline fault: Mobile phones: a mobile phone is a solid backup, in case, something goes wrong with your landline, as they are portable and easy to use. VoIP: VoIP communication allows for voice calls to be made over the internet. As long as the fault hasn’t affected your internet service, you should be able to make and receive calls. Social media: in the absence of a landline, leverage your business’s social media presence to maintain a presence with customers and give them an alternative way to get in touch.
