1.3) Advantages of Remote working system

Increased productivity and greater work is satisfactory. For Employees, it also reduces travel time. So, they are low stress.

Voice calls, E-mails & Instant Messaging, are the right time.

Connect to any broadband connection in the world and interact with the office by accepting voice calls, mails, E-mails and Faxes - as though they were at home office.

Use a single mobile phone to work seamlessly inside and outside the office, switching between mobile and wireless Wi-Fi connections.

Integrate with office applications using voice commands to say, fetch latest sales figures.

Reduce costs by linking first to the office system and then to the public network from any location.

People who work at home office can also be easily integrated into the office telephony environment

Disadvantages of Remote working system

They are based on site staff to be available when you need it, so it is important that you are attentive to their needs. Even when traveling you should still leave your office to be aware of when and where changes can be achieved with time to consider the effect.
