Recommended Headsets for Customer Service Professionals

The headset should be a professional headset which is planned for the open office and long time use. The user experience is always personal and therefore the employees should be involved in the selection of headsets.

Keep following issues in your mind when doing the selection of headsets:

Wired headset is recommended because of endless speech time and better video – audio sync.
On-ear and over-ear models are both recommended. However, this depends on user preferences.
Noise reduction with switch on/off is recommended.
Red light signal when on the video/phone call is very useful
Mute is recommended feature in microphone. Mechanic mute on/off is very useful feature (microphone up = off).

We recommend following headset models:

1. Jabra Evolve 80 MS
2. Jabra Evolve 40 UC

Speed Requirements of Internet Connection

Internet connection must be fast enough. Vooler uses better and lower quality video based on the network speed. Notice that the bottleneck of the Internet speed might be in Internet backbone or your own connection. Below are listed the recommended speeds:

Speed from computer to server (upload)
- Recommendation: 2 – 4 Mbps / user in the same local network
- Minimum: 0.5 Mbps / user in the same local network
Speed from server to computer (download)
- Recommendation: 1 – 4 Mbps / user in the same local network
- Minimum: 0.4 Mbps / user in the same local network

Requirements for the Firewall

Vooler uses the Internet connection listed below. Normally they are accepted in home and company networks. However, if the organisation has stronger firewall protection, the connections below must be opened for Vooler. Without these connections the videos are not working. Ask your IT support to make the settings below in your firewall.

port 443/TLS	95.216.248.0/24	HTTPS
