Networking,QualityofService,andFirewalls
This section describes important information for Evolution PBX regarding networking,
Quality of Service, and Firewalls. Evolution PBX, SIP, and VoIP use certain TCP and UDP
ports for communication. Typical LANs do not interfere with these protocols but
connecting devices over the Internet may require forwarding one or more of the ports
defined below. Refer to your router or firewall manufacturer for information about how
to forward ports on your device.
Port Description
22 TCP port 22 is used for SSH, a remote terminal configuration protocol. Intuitive Voice Technology
uses this port for remote diagnostics and custom configuration requests. Forwarding this port from
the Internet to Evolution PBX is optional but may be required for many support and configuration
requests.
69 UDP port 69 is used for TFTP (Trivial File Transfer Protocol) configuration file loads. Remote VoIP
telephones and devices that are automatically provisioned require this port to be open. Forwarding
this port is required if automatic configuration is desired for remote devices (devices must be
supported by Evolution PBX as a specific device. See the section Phone Extensions for more
information about specific devices).
80 TCP port 80 is used for standard Web traffic (http). Forwarding port 80 allows access to the
Evolution PBX Web interface. Intuitive Voice Technology uses this port for remote diagnostics and
custom configuration requests. Forwarding this port from the Internet to Evolution PBX is optional
but may be required for many support and configuration requests.
5060-
5061
TCP and UDP ports 5060 and 5061 (sometimes 5062-5063 are referenced as well) are used for SIP
(Session Initiation Protocol) to provide call signaling and registration information. 5060 must be
forwarded from the Internet to Evolution PBX for remote devices to register and make calls over
the Internet (5061-5063 may be required). These ports are also mandatory for VoIP service
provider accounts.
10000-
20000
UDP ports 10000 to 20000 are used for RTP traffic (Real-time Transport Protocol). RTP is the
protocol that transmits the audio for a telephone call. 10000-20000 must be forwarded from the
Internet to Evolution PBX for remote devices to register and make calls over the Internet. The
whole range may not be required depending on what type of telephone you are using and how
many calls you will make over your Internet connection. These ports are also mandatory for VoIP
service provider accounts. Check with you VoIP service provider to verify the ports that they
require to be forwarded (some service providers may require 8000 to 10000 rather than 10000 to
20000).
