Technical Requirements for Contact Center

Computer Requirements

Minimum Requirements

Processor: 2.0GHz Intel Core i3 or better
Free Space: 20GB or 10% of main drive
USB Port: 2.0 (at least 1 free)
OS: Windows 10, MAC OS Mojave
Wired Internet Connection

Recommended Requirements

Processor: 3.0GHz Intel Core i5 or better
Free Space: 20GB or 10% of main drive
USB Port: 3.0 (at least 1 free)
OS: Windows 10, MAC OS Catalina
Wired Internet Connection

Note: Using a faster computer will provide a more reliable connection when non-Ytel programs (like your CRM or other web applications) use system resources heavily. Underpowered computers can exhibit choppy audio (“jitter”) that may result in a terminated connection.

Operating Systems

Contact Center requires Mac OS Mojave, Windows 10 or newer, or ChromeOS*.

Note: anti-virus, firewall, or other software-based system monitoring utilities may cause unintended performance issues and may need to be adjusted and/or disabled.

*ChromeOS requires the use of a wired USB headset. While Bluetooth headsets are supported on certain Chromebook models - the headsets must work natively and not require 3rd party drivers/software. Ytel recommends you use a wired USB headset for best performance. In addition, while Ytel produces and services do work on a variety of Chromebooks, not all makes, models, or manufacturers are supported. Ytel offers no guarantees regarding the functionality of its services on Chromebooks.

Headset Recommendations

We recommend a quality USB headset from such brands as Logitech, Plantronics, Panasonic, or Jabra. Look for features like:

  • Noise cancellation
  • In-line or on-ear audio controls
  • Mute functionality

Ytel does not recommend Bluetooth, wireless or analog headsets with a "traditional" mini pin connector.

Network Equipment

A clean, high-speed network is required.

Ytel recommends enterprise grade telecommunications equipment. Avoid "consumer grade" or ISP supplied routers. We suggest Juniper, Cisco, or Ubiquiti.  

Network hubs are not recommended. Switches costing $250 or less are generally not recommended.


Create firewall rules to open ports to/from Ytel.


  • Allow all traffic from your network to ours (TCP & UDP)
  • Allow all traffic from our network to yours (TCP & UDP)

Ytel Network

These are our IP addresses in case you want to adjust your firewalls:


Note: We employ remote non-intrusive diagnostic and monitoring tools that rely on ICMP. For best performance, please enable on your end.


Minimum Requirements

5 Mbps per agent on your network
Example: 50 agents = 250 Mbps*

Recommended Requirements

10 Mbps per agent on your network  
Example: 50 agents = 500 Mbps* 

Running Ytel Contact Center at minimum recommendations requires an expert network administrator to shape traffic.  Ytel’s web interface and softphone combined will consume approximately 500-1000 Kbps running WebRTC.  The Ytel products and services require uninterrupted communication between your workstations and our data centers.

*Note: Internet speed needs to be symmetrical.

30 Mbps Down
10 Mbps up
Wired Ethernet Connection

We use such providers as:

  • NTT America
  • Internap (INAP)
  • Level 3
  • Hurricane Electric
  • Public and private peering

If you are unable to establish business services with one of the named providers, choose a reputable provider with a direct connection to one of our preferred providers. We recommend against using consumer grade Internet providers.
