What our customers say

Covid-19 Business Support Systems – remote working solutions

Cavendish is committed to supporting customers in the face of the current pandemic through the use of technology to enable ‘business as usual’ even with staff working in isolation from home. We offer a number of solutions for remote working and to allow your business to continue working as normal.

Microsoft Teams Direct Routing

Microsoft Teams Direct Routing

Microsoft Teams is everywhere at the moment. It is the go-to flexible office and homeworking application that comes free with Office 365 and as their advertising says, “socially distant but virtually unstoppable.”

Cavendish provides Direct Routing for Microsoft Teams allowing users to make both internal and external calls, completely integrated from within the Teams application that many employees are already familiar with. The Direct Routing comes with free calls to local, national, and mobile numbers and users can receive external inbound calls allowing for a location independent call centre capability. A seamless experience for all of your users, whether they are office based or homeworking.

  • Working from home as if you are in the office
  • Receiving calls from your main numbers
