Table of contents

To use RingCentral Engage Voice services, you must meet certain network requirements.

1. Connectivity and bandwidth requirements

  • A connection of at least 10/100 Mbps over wired Ethernet is required. Wireless connectivity is not recommended.
  • You must disable the IPv6 protocol on any applicable network interfaces.
  • For voice traffic, you must allocate at least 128 Kbps of dedicated bandwidth per agent in both outbound and inbound directions. This requirement doesn’t account for the extra bandwidth for enterprise data traffic.
  • All customer sites and points of network connectivity must use enterprise-grade network circuits with associated service-level agreements and support contracts from the relevant Internet Service Providers (ISPs). RingCentral doesn’t recommend using residential-grade network circuits or circuits without support contracts.

2. Whitelisting of domains, IP addresses, and ports

The following tables specify outbound and inbound whitelisting rules for domain names and IP addresses. Outbound rules pertain to traffic initiated from a RingCentral endpoint to the Engage Voice service in the RingCentral cloud. Inbound traffic rules for RingCentral Engage Voice need only be configured when you’re using web services, SIP trunks, or FTP jobs.

To support Engage Voice, you must whitelist the domains, IP addresses, and TCP/IP ports listed in Table 2.1.1, Table 2.1.2, Table 2.2.1, and Table 2.2.2 in your enterprise firewalls.
  • Table entries marked as deprecated are only relevant for legacy Engage Voice services, and should be ignored for new deployments.
  • Unless otherwise specified, all IP addresses correspond to Engage Voice cloud service addresses.
  • There are several differences between the domain names and IP addresses for Engage Voice cluster C01 (aws80, vacd.biz) and cluster C02 (aws82, virtualacd.biz).
  • The port tables indicate which enterprise firewall ports must be opened to allow enterprise clients to receive and transmit traffic between the client and the Engage Voice cloud.
  • In Outbound Rules tables, destination ports refers to port outbound firewall ports that are used for communication with cloud servers.
  • In Inbound Rules tables, destination ports refers to inbound firewall ports.
  • For Inbound Rules tables, we recommend opening only those ports needed for a specific Engage Voice deployment. For example, if you’re not using inbound webhooks from RingCentral, you need not open the corresponding ports.
  • Contact RingCentral Support if you need to determine which cluster or ports to use for a specific deployment.
