Terminology
The following terms are essential in understanding your network requirements for 8x8:
- Jitter: A measure of the time interval between data packets as they reach their destination. A low degree of jitter indicates a relatively steady stream of data packets.
- Packet loss: Data, such as a VoIP transmission, is sent over the Internet in the form of packets. Packet loss occurs when some of these packets do not arrive at their destination. For each packet loss, a small amount of speech is cut out. If the degree of packet loss is high, conversation audio can sound very choppy, delayed, or unclear.
- MOS score: The higher your MOS score, the better your VoIP experience will be. A MOS score is measured on a scale of 1 to 5, in which 5 represents the best possible call quality, and 1 represents the worst possible call quality. The range is subjective and based on normative data collected from experimental trials.
Firewall Guidelines
With regards to Firewall guidelines, It is advisable to either exempt 8x8 traffic from Deep Packet Inspection (DPI) and Intrusion Protection or ensure that appliances performing these operations can inspect the traffic without inducing measurable delay.
Default Recommendations
DNS
When using a Voice Only VLAN (a Virtual LAN with only Hard Phones, and no computers on it), 8x8 recommends that you set the 8x8 GTMs, 8.28.0.9 and 192.84.18.11 as the Primary and Secondary DNS servers in the VLANs DHCP Scope. An alternate option is to implement conditional forwarding of 8x8.com and packet8.net on your local DNS servers to 8.28.0.9 and 192.84.18.11, which are 8x8's DNS servers. It is not recommended to set conditional forwarding on your Data VLAN, and/or if you have only one network. If your network only consists of a single LAN (you are not using VLANs), 8x8 can set the DNS of your hard phones to the GTMs. This ensures proper Geo Routing of your 8x8 traffic to the closest 8x8 data center for each location.
8x8 UCasS 8x8 Work for Mobile and 8x8 Work for Desktop Clients use the 8x8 GTMs directly (with a fallback of the local DNS); thus, no additional work is needed to ensure proper routing of the traffic for UCaaS Clients.
8x8 does not recommend the use of DNS servers that make use of AnyCast, as the Geo Location can be unpredictable.
NTP
8x8's recommendation for NTP is to allow the default NTP setting of pool.ntp.org through the firewall. If your internal security requirements do not allow for external NTP, our advice is to use Option 42 in your DHCP scope to override the NTP setting to an NTP server of your choice. Should you not have an internal NTP server, use ntp2.packet8.net.
SIP-Application Level Gateway (ALG)
By default, 8x8 enables SRTP, which supersedes SIP-ALG functionality for a list of equipment that supports SRTP see our list of SRTP Compatible Equipment. 8x8 recommends for NON-SRTP Users that SIP-ALG be disabled on all your Layer 3 Network equipment, as SIP-ALG can cause issues with SIP messages. Please review and test to ensure that disabling SIP-ALG on your networking equipment will not impact other existing services on their network. For more information on SIP-ALG and possible solutions for disabling, see Disabling SIP-ALG in Your Router or Firewall.
SIP-ALG (Application Level Gateway) is a feature in which the layer three network equipment can manipulate the payload section of a SIP Packet to change the private addressing to be public address. As the phone or 8x8 Work for Desktop/8x8 Work for Mobile is not aware of the public address, all payload information references private addressing. Edge devices attempt to correct this by opening all SIP packets and manipulating the payload (body) of the packets by replacing private addresses with the public IP of the edge device and the Natted port. Unfortunately, many devices do not adequately manipulate these packets causing them to be invalid or contain incorrect information. For this reason, 8x8 recommends that this function be disabled for non-SRTP users.
Firewall Rules
Our recommendation is to create an OUTBOUND Policy "Internal to 8x8" rule in your firewall. This is a highly secure action as it is only opening outbound traffic towards a known destination (8x8 data centers). The list of 8x8 subnets (or Domains) is later in the document.
We recommend setting firewall session timers as follows to prevent premature NAT session changes that can cause de-registration, intermittent one-way audio, and phones not to pick up or ring when using certain firewalls:
- UDP session timer: 660 seconds
- TCP session timer (TLS connections only, port 5443): 300 - 700 seconds
Application and Browser-Based Interfaces
All 8x8 services are deployed within the IP address spaces listed in this document and identified by one of the domains listed in this document. Outbound requests made to these ranges on port 80 (HTTP) will be redirected to port 443 (HTTPS) and customers should allow both outbound ports to the IP/Domains.
To ensure the utmost security as you use your 8x8 services, beginning February 28, 2021, access to the 8x8 Configuration Manager for Contact Center, Agent Desktop, along with API calls to these systems, will require up-to-date web browsers or libraries compliant with TLS 1.2 or better:
The following browsers have been verified by 8x8 QA to support the changes occurring February 28, 2021:
- Google Chrome version 70 or later
- Mozilla Firefox version 48 or later
- Microsoft Edge (any)
- Apple Safari version 9 or later
Proxy Server
8x8 only supports using a proxy for TCP port 80 and 443 (HTTP/HTTPS) traffic, all other traffic (Video and Audio) should bypass your proxy. 8x8 has made every attempt to ensure that 8x8 Work for Desktop application will respect the proxy settings of the system 8x8 Work for Desktop is running on. 8x8's web applications (Contact Center Agent Interface, Configuration managers, Analytics, and so forth) are, by nature, proxy aware and will respect the proxy setting of the system/browser.
Physical Instruments
For all approved telephony devices (endpoints), Outbound requests made via HTTP over TLS (HTTPS) on port TCP 443 to all 8x8 domains listed in the Domains section of this document without restriction to specific IP address ranges.
Provisioning Note: Poly devices can make use of Poly Zero Touch Provisioning (ZTP) and Poly PDMS service. Each of these services require HTTPS traffic to be allowed to Poly. For more details see Whitelist Zero Touch Provisioning Services for Obihai and Poly Devices. Device Access to Poly’s IPs is not required for 8x8 services, it will assist/speed deployment for new devices.
Citrix
Customers using 8x8 Work for Desktop should refer to Citrix VDI Integration with 8x8 Work for Desktop & Web for more details.
Network Considerations and Recommendations
Below are Network considerations and recommendations that customers should review and adapt as appropriate, as they may not ally to all installations.
Requirements
| Parameters | Requirements |
|---|---|
| Poly Zero Touch Provisioning (ZTP) | Allow Poly Zero Touch Provisioning, alternative options can be found in Setting Up ZTP Override. |
| TLS | TLS 1.2 support is mandatory. |
| Wiring | At least Cat 5 (preferably Cat 6) wiring for networking devices, and IP phones that use a wired connection. |
| WiFi | Strong and consistent WiFi connection for networking devices, and IP phones that use WiFi. |
| PoE (recommended) | See Device Manufacturer Data Sheets. |
| Packet loss | 0% packet loss |
| Jitter | <20 ms jitter |
| Network latency | <100 ms latency to 8x8 data centers. VoIP services are known to work even in higher latency conditions up to 150-200 milliseconds. However, this must be maintained consistently with no packet loss. |
| Bandwidth requirement | Voice UCaaS and CCaaS:
Video Meetings Upstream:
Video Meetings Downstream:
Downstream max bandwidth in a conference of n people would be 2.5Mbps + (n-2)*200kbps + 40kbps Make sure you have 50% of your available bandwidth free to accommodate any spike in usage. Always assume that at least 35% of your users are on call at any time. However, depending on your company's use case, you may have a higher percentage. Note: When setting up devices to use an uncompressed voice CODEC, enable both G.711a law and G.711μ law capabilities available on the device. This prevents call quality loss by eliminating transcoding of international VoIP calls. This has no impact on bandwidth requirements, as either choice uses 80 Kbps per call. Transcoding does increase latency. To estimate the network bandwidth required to support a VoIP station:
When calculating total network load, be sure to include all applications that use the network, especially applications with high bandwidth requirements (such as video conferencing). |

Considerations
| Parameters | Considerations |
|---|---|
| If running a converged network for voice and data | Configure VLANs to separate the traffic. Ensure that the Phone VLAN has the following DNS and NTP in its DHCP scope:
Note: The recommended DNS does not resolve any other domain except 8x8.com and packet8.net. For more information on Poly and VLANs see Poly Devices VLAN Recommendations. |
| DHCP scope | Ensure that there are no rules specified to force any provisioning server or NTP server to deviate from default 8x8 values. For provisioning servers, you must disable Option 66/160. |
| Maximum Transmission Unit (MTU) | The network must support an MTU of 1500 bytes per packet. The MTU is the size of the largest protocol data unit that the layer can pass onwards. This is for Non-SRTP Communications only. |
| WAN failover | We highly recommend that you use dual WAN connections in a failover state by using WAN link redundancy (Active / Standby). Dual WAN connections in load balancing (Active / Active) may not be supported due to the multiple ways to implement, speak to your 8x8 engineer for supported options and/or recommendations. |
| VPN use cases | If your remote users or Internet egress use a VPN tunnel, make sure that the 8x8 traffic does not traverse it. Consider a Split Tunnel to have local Internet egress for 8x8 traffic. In addition, split DNS to resolve 8x8 domain queries locally. Speak to your 8x8 engineer for more information. |
| Internet Access Requirements |

| NAT Requirements |

QoS / Priority
The basic approach of handling QoS for 8x8 traffic within your network is by DSCP markings as provided by the applications and approved devices. When configuring QoS, on circuits that support QoS, external to your network 8x8's recommendation is to identify 8x8 traffic based on source/destination network, (i.e., not by DSCP markings, ports, channels, etc.). RTP will make up 90+% of your traffic. That way, any of your traffic that is sourced/destined to any of the 8x8 networks should be treated with the highest priority.
If the majority of your users are on Wi-Fi rather than Ethernet, make sure you follow the best practices in Wi-Fi deployment to ensure plenty of coverage.
8x8 Meetings does not currently mark the meetings traffic; our recommendation is to set priority (EF) on the predictable port of UDP 10000.

8x8 Datacenter IP Ranges & Domains
Note: In the process of connecting to Secure HTTP servers and setting up TLS connections, the certificates used in the connections will be validated by the issuing authority. Ensure you allow access to any/all issuing authorities.
Provisioning Note: Poly devices can make use of Poly Zero Touch Provisioning (ZTP) and Poly PDMS service. Each of these services require HTTPS traffic to be allowed to Poly. For more details see Whitelist Zero Touch Provisioning Services for Obihai and Poly Devices. Device Access to Poly’s IPs is not required for 8x8 services, it will speed deployment for new devices.
IP Ranges
Below is a list of IP Ranges that are used by 8x8 products and applications. Access Control List (ACL) and Quality of Service (QoS) flags indicate if the subnet should be included in your ACL and/or QoS Lists. There is an export option at the top of the list. When a Port range of * is referenced it refers to All Ports listed above in the Data Center Ports section.
Domains
Below is a list of domains that are used by 8x8 products and applications. There is an export option at the top of the list. When a Port Used range of * is referenced it refers to All Ports listed above in the Data Center Ports section.
Contact Center as a Stand Alone Service
