UCi2i VC Endpoint Firewall Requirements

Due to the implementation of our secure video network, there are a few firewall rules that may be required depending on your network configuration to allow communication with the UCi2i infrastructure. This is to provide our customers with the best technology on the market.

Note: you can download this guide in PDF from the bottom of this page.

What this means to you

In order to take full advantage of our service, we MAY require you to make some changes to your firewall to allow communication from your current hardware/software to our Firewall Traversal Servers. Please note that many firewalls work without any modification at all.

If you wish to test your firewall before deploying our managed video service, then call test@dial.vc (more instructions here). and you’ll be prompted to speak “1…2…3” and this recording will loop back to you. If you can see and hear this then you’re good to go. 

What addresses and ports does video conferencing use?

Please see below firewall port requirements. In order to provide resiliency, we will require you to open ports to multiple addresses.

Complete Firewall Port List

To enable the UCi2i service a complete list of the ports required is below. Should, you require information on the individual protocol requirements then please see the next section for a breakdown of services.  

Defined Services Firewall List

SIP Proxies

Please ensure that the correct ports are open depending on the video conferencing system you are using. There are different port requirements for SIP depending on what signalling method your system is using. The media requirements are the same regardless of the signalling method. Note these outbound exceptions are required to establish a UDP/TCP session. There are absolutely no inbound pinholes required.

H323: Using Assent Firewall Traversal

If your video conference system supports Assent traversal, you MAY need to open the ports below in order to register to our firewall traversal server.

H323: Using H.460.18/19 Firewall Traversal (used by all Polycom/Lifesize devices)

If your video conference system is not a Cisco Telepresence device and supports H.460.18/19 firewall traversal, you will need to open the ports below in order to register to our firewall traversal server.

Browser-based Video Calling (a.k.a. WebRTC)

We offer browser-based video calling - all major browsers are supported. This is typically known as WebRTC but we offer more than that as WebRTC is limited to Google Chrome, Firefox and Opera. We also provide service to any browser that also supports Adobe Flash. To allow this feature to work, the following ports will need to be opened:
