In this article, we describe how to configure your firewall for SIP operation.

  • Open firewall ports

We recommend opening firewall ports towards your PBX server with any/any rules, or the following ports:

5060 TCP & UDP
5061 TCP
10000-20000 UDP
443 TCP
80 TCP

If you are using our Auto-Dialer please open
2052 TCP
2053 TCP

  • Allow monitoring for IP addresses

Allow ICMP ping and latency monitoring for the IP addresses below. Allowing it will enable the CommPeak team to provide you with optimum support. 

116.202.64.40
104.199.5.135
109.169.12.37
23.19.63.66
139.162.33.28
35.198.29.133
169.57.216.71
38.91.107.164
96.47.228.250
38.91.100.151
167.88.61.171 

Make sure to add the IP address of your PBX server as well.

TIP

You can find the IP address of your PBX server at My CommPeak > Labs > PBX Instances.
