Network requirements for phone channel

Created by Fawzia Aleem, Modified on Tue, 18 Jun, 2024 at 4:33 PM by Fawzia Aleem

To use the built-in phone channel, here is a basic requirement you will need to get up and running:

Minimum 8kbps per agent per call. The more the better.
- You can benchmark your network connectivity either in pingtest.net or in speedtest.net. Our service provider recommends "A" rating from pingtest for seamless voice data transmission.

For an even better call quality experience, we recommend you to enable DSCP and whitelist the following IP address range for QoS:

IP Addresses

Range From	Range To
54.252.254.64	54.252.254.127
177.71.206.192	177.71.206.255
54.171.127.192	54.171.127.255
52.215.127.0	52.215.127.255
54.65.63.192	54.65.63.255
54.169.127.128	54.169.127.191
54.172.60.0	54.172.61.255
34.203.250.0	34.203.251.255
35.156.191.128	35.156.191.255

DSCP

Additionally, enabling DSCP by default in compatible browsers (currently Google Chrome) will tag WebRTC media packets, enabling differentiated handling on a LAN, so that real-time media can be prioritized above other network traffic. All of this will ensure a better overall call quality experience.
