Browser calling for RingCentral allows users to make calls directly from your Zoho Desk without having to toggle between the help desk account and RingCentral software. WebRTC plugins are installed to give hassle-free browser calling and a real-time communication with the end user.
Let’s take a look at the following network connectivity components that are required to be included in the user network.
Firewall Configuration
Firewall includes a Wide-Area Network interface such as a DSL, Ethernet or a cable modem. Firewall configuration allows outgoing TCP and UDP port control to the public Internet from the browser that uses the RingCentral client. It also enables the opening of ports so that the client server has time to exchange information with the remote server.
Router
Router provides routing, traffic directing, packet forwarding and also provides support for ping and traceroute ICMP, bandwidth management, packet prioritization and smart packet inspection.
Firewall Access
Firewall access ensures that the outbound and inbound firewall port is opened between the internal user network and the ISP WAN for the applications such as, Call control, RTP media, telephone provisioning and registration, and Auxiliary services. This firewall access allows the call control and media path connectivity.
WebRTC plugins
WebRTC helps real-time multimedia applications to function without any installation of additional extensions, or plugins. It enables Real Time Communication to the end user independent of the browser being used. The following are the ports to be opened before enabling the browser option under RingCentral call preferences.
| Traffic Type | Protocols | Source Port Number | Destination Port Number |
| Signaling and (secured) Media (WebRTC) | HTTP/TLS/TCP, STUN/UDP | 5060, 6182, 8080, 8083 | 5060, 6182, 8080, 8083 |
