Before You Start - CyberData 011186 Configuration Manual

3.0 Before You Start

This configuration guide documents the integration process of a CyberData SIP Intercom.
Network Advisories
Zoom uses a Fully Qualified Domain Name (FQDN) for the SIP server and Outbound Proxy
addresses. The CyberData Intercom needs to perform a DNS A query to resolve the IP address of
Zoom's Outbound Proxy FQDN. It is necessary to ensure the configured DNS server(s) have an
A record for the Outbound Proxy address.
In addition, be sure to verify the following ports are available for the intercom to use:
• TCP 5060-5061, 5091 (SIP)
• UDP 10500 (RTP)
The intercom will need to traverse the public internet in order to operate with Zoom in the cloud.
The intercom's paging extension uses SIP port 5060 to receive SIP messages. The Nightringer
extension uses SIP port 5061 to receive SIP messages. Both extensions will send SIP messages
to port 5091, the port used by Zoom's Outbound Proxy.
SIP ports 5060-5061 and RTP port 10500 are the default values on all noted firmware levels.
Alternatively, SIP ports for the paging and Nightringer extension are configurable on the SIP
page of the web interface.
The RTP port setting on the SIP page is used for both extensions.
The CyberData Discovery Utility can be used to locate CyberData devices on your network.

Note: DHCP addressing mode is enabled on default on all noted firmware levels.
