IP Addresses & Ports
The following protocols and ports are used by our systems:

The following ports are used by the ThreePBX Mobile App:

- UDP - 4998, 10000-65535(for RTP/RTCP packets)
As a general matter, you will not need to do anything with these IP addresses, because the provisioning servers will take care of SIP Device configuration. We will provide you with domain names that will resolve to these servers as necessary.
In certain situations, however, it may be necessary to allow these ports in your firewall. We recommend utilizing the subnet ranges, as there may be more than one server on one Geo Node that can serve the same function. The following are Subnet Ranges and IP addresses that are in use by our systems:
- 70.42.44.0/24 - New Jersey
- 75.98.50.0/24 - Dallas
- 216.24.144.0/24 - Las Vegas
- 199.21.246.224/27 - Minneapolis
- 50.112.101.114, 54.245.113.67, 52.32.130.83, 75.101.128.37 - Instant Fax Servers
New IPs for failover
