Network Configuration Guide

The hostnames and IP addresses used by our services can be found in the download link below. This information can be referenced whilst you are configuring your firewall if you have a restrictive outbound policy.

Network Configuration Guide

Network Requirements

• RTP voice traffic must be presented from the same public IP as the SIP signalling traffic. Where sites have multiple internet links please use failover instead of load balancing.
• Phones must have a working DNS server.

Network Recommendations

• The web UI of any phone should be disabled. If access is required then please ensure it is promptly disabled after using.
• SIP ALG should be disabled on any device performing network address translation (NAT).
• Phone should have private (RFC 1918) addresses and access the internet via a NAT device.
• Default credentials should always be changed.
• High risk or international calls should only be allowed if necessary.
• The NAT timeout should be set to 3600 seconds.
• Routers should allow fragmented UDP packets. This helps services such as busy lamp field.
• Avoid configuring any port forwards on your router or firewall that would allow access to a phone from the internet.

Call Recording Copy

If you are using the call recording copy service in Uboss you will need to allow inbound connections from our servers that initiate the copy. The source IP address will be from within this range.

83.137.182.0 /23 (83.137.182.0 - 83.137.183.255)

Webex

Webex have a dedicated help page that fully details any URLs or IP addresses that may need to be open. We have listed some in the network configuration guide, but for reference please see this page.
