| Item | Requirement/recommendation |
|---|---|
Ports (server-side) | Signaling: 443 Presence: 443 Real-time Transport Protocol (RTP): 10,000-20,000 |
| Ports (client-side) | Softphone selects any available port from the ephemeral range—on most machines ports 1,024 to 65,535. |
| Protocol | Signaling: TCP Presence: TCP RTP: User Datagram Protocol (UDP) |
| Bandwidth | 100 kilobits per second (kbps) (symmetric) |
| Firewall configuration | Firewalls should allow outgoing UDP to the public internet from the browsers that will be using ContactPad with WebRTC, and allow return traffic in response. NewVoiceMedia WebRTC servers use dynamic IP addresses from a public range of IP addresses. We therefore strongly recommend that your firewall does not limit access to a specific range of IP addresses. The IP addresses used can be any of the IP addresses within the NVM platform. For a list of potential IP addresses, see https://ip-ranges.amazonaws.com/ip-ranges.json. |
| Browser | Google Chrome™, latest version |
| Salesforce integration | WebRTC is only supported in Salesforce console interfaces. For information about Salesforce console, see Salesforce help. |
| Backup phone | All agents should have access to an alternative phone as a backup for WebRTC. |
| Alternative phone | We recommend that agents have access to an alternative phone for non-ContactWorld related calls. |
