3rd Party Firewall Rules
This page is part of the Network and QoS guides.
Networking
Step one would be, can you see our servers? You can check here: https://core1-dal.vestednetworks.com/webtest/webtest.php
After you have confirmed that our servers are reachable via HTTPS/SSL ports, you will need to make sure some more VoIP specific ports are open on your network.
IP Addresses
The easiest way is to allow any ports to and from the following IP addresses to pass through your firewall.
If you cannot open all ports to the following addresses, you must open the ports listed below to the following IPs .
Allow
Voice/Video Traffic
- Primary Addresses: 216.58.152.240/28
- Secondary Addresses: 74.63.180.0/28
Fax Traffic
- ATA: ataserver.ipfax.net & ataini.ipfax.net
Voice/Video Ports
If you cannot open all ports to an IP address, you may need to open specific ports through your firewall.
The following ports must be allowed to pass through your firewall to ensure proper function of your phone systems.
Allow
SIP (SIP Handshaking)
- UDP/TLS/TCP, in/out: 5060, 5061, 5062
WebSockets (NOVA Web Softphone, Mobile App)

VoIP Bandwidth Requirements
Our default compression uses 90kbps up & down for one single call.
Example: 6 active calls is roughly 540kbps up & down reserved. This would be a normal use case for ~20 seats with an average use of 30%.
