How can we Help?

To ensure a smooth experience with Talkdesk, you can find below a list of requirements and best practices that you need to keep in mind when setting up your hardware, software, and network.

✔️ Getting Started: Checklist

1. Review the operating environments that the agents will use;
2. Make sure everyone is using a wired headset with the best configuration;
3. Connect via Ethernet and read the recommendations below for VPN/VDI usage;
4. Where will the Agents work? Depending on whether it's home or the office:
   • Make the necessary changes in the Firewall and QoS;
   • Follow our alternatives to Wi-Fi when Working from Home.
5. Test your connectivity using our Network Test Tool.

Please continue reading for more details.

💻  Supported Operating Environments 

When setting up the operating environment to work with Talkdesk, please review these requirements:

• Operating System (OS): Windows 10 / OSX 10.14+ / Linux 64bit (Debian 9 or Red Hat 8 based distros) / Chrome OS;
• RAM: Recommended 8 GB of RAM;
• CPU: Intel i5 / AMD Ryzen 5;
• Browser: Google Chrome configured as the default browser and updated to the latest version;
• Security: If you use any software or Proxy that can block applications, please include Callbar in the allowlist.
• Virtualization: avoid using the Callbar usage inside a VDI and read the recommendations below for VDI usage;

🎧  Headsets

When choosing headsets to handle calls with Talkdesk, please consider the following:

• We recommend using a wired headset with a 3.5 mm jack (analog) port;
• You can use a USB headset but this option will consume resources from your computer;
• We also do not recommend Bluetooth/Wireless headsets for professional long-term usage:
  • The battery level is a factor on these devices (the lower the battery, the lower the range);
  • Being a wireless device, it suffers from interference from other wireless devices in the area;
  • Bad reception or increased latency is common, which could falsely point to a network issue.
• If you use Windows OS, follow the recommended settings for Callbar.

🌐  Network

Internet Bandwidth

Make sure that enough bandwidth is reserved to work with Talkdesk:

• A good rule of thumb is a 1Mbps symmetrical connection per device;
• Avoid having other people using/sharing your bandwidth while you are on a call, especially if it involves activities that consume a considerable amount of bandwidth, such as:
  • Streaming multimedia content (4K/HD/Full HD Movies);
  • Online gaming;
  • Downloading large content (such as torrents).
• Disable recordings on any DVR / Set-top boxes, as these can consume bandwidth.

Connection best practices

Make sure to follow these guidelines regarding the type of connection:

• Ethernet is the preferred connection type. Use a Cat 5E cable, or above;
• Set the following DNS servers (if possible):
  • Primary DNS: 8.8.8.8
  • Secondary DNS: 1.1.1.1
• Avoid using VPN (Virtual Private Network). If you do need to use a VPN, split tunneling must be configured in order to ensure that all traffic from Callbar is routed directly to the internet instead of through the VPN;

• Avoid VDI (Virtual Desktop Infrastructure) or Remote environments.

Although practical from a systems administration perspective, virtual/remote desktop environments are still a suboptimal solution when it comes to real-time voice as users are much more prone to suffer call quality constraints. From a network perspective, it is something we advise against.

For best results, Talkdesk recommends that customers:

1. Move the agents from the VDI environment / thin clients to local dedicated desktop machines;
2. Configure Callbar to "Connect to External Device" and:
   2.1. Receive the calls on an External Phone, for example, the agent cell phone (possible call costs associated with this setup);
   2.2. Receive the calls on a SIP Phone.

Successful usage of Talkdesk's Callbar in a VDI environment may require significant tuning and additional testing at scale to be carried out by the customer's system administrator(s) / VDI provider(s).

Office and Home

If you and your agents are:

• Working from the Office: Make sure to implement the required Firewall and QoS configurations. 
• Working from Home: If you can't use Ethernet, please follow our Alternatives to Wi-Fi.

Using Wi-Fi as a Temporary Solution

As you can see in the above image, Wi-Fi is prone to packet loss, latency variation, and jitter.

If you are waiting for an Ethernet or PLC (powerline) adaptor and need to use Wi-Fi temporarily, please follow these guidelines:

• Use the latest standards (> Wi-Fi 5 IEEE 802.11ac) with MU-MIMO support and the 5 GHz band, as opposed to the 2.4 GHz. This will reduce the range but decrease the probability of environmental interference;
• Connect as few devices as possible to the same AP, to better concentrate and serve your own;
• Upgrade to a mesh AP network. It allows reachability from several points in the home and repeats the traffic between the cells. This way, the packets are not lost if a specific area is affected.

🎛️  Final Step: Testing your Network Connection

Finally, you can test the quality of your network connection by using the Talkdesk Network Test Tool.
