Phones Pro network recommendations and setupLast updated on 03/22/2022
Learn about your recommended network options and which one to use for Phones Pro.
Things to know
Dialpad does not support virtual private networks (VPNs). If your company uses a VPN, set up a split tunnel and direct Dialpad traffic outside of the VPN.
You can use a virtual LAN (VLAN) for managing security and routing policies. You can also use a voice VLAN for security purposes. Note: You are required to set up a voice VLAN when workstations are linked together through IP phones.
For better voice quality, we recommend using either a high-speed DSL, cable, or fiber-optic connection with dedicated upload and download bandwidth for the voice of at least 100 kilobits/second for each voice line you plan to run.
Set wired connections
Wired connections provide the best quality experience. Your network should use cabling that meets the network speed specifications.
Set wireless connections
If you use a wireless connection, be aware of the following issues:
Multiple Wi-Fi bandwidth frequencies
Type of frequency for wifi connection
Phones Pro supports network routers, switches, and firewalls. Make sure your network hardware supports the following features:
