Port reference information for your Business Digital Voice with Webex service
Business Digital Voice with Webex is a hosted unified communications solution operating in the United States of America.
The service has multiple components including voice, video, desktop and mobile applications, web applications, and service quality tools. These components require communication between devices on the customer’s local area or wireless network connections and servers in the Business Digital Voice with Webex infrastructure. For this communication to function properly, customer security devices, such as firewalls, must not block IP addresses and TCP/UDP service ports used by the Business Digital Voice with Webex service.
The following topics of this guide provide information necessary to properly configure a customer’s firewall to allow all communications between customer devices/applications and Business Digital Voice services.
If a router and/or firewall is “SIP Aware”, that is, it has SIP ALG or similar enabled, we recommend that this functionality be turned OFF for correct operation of the service. See the relevant manufacturer's documentation for more information on how to disable SIP ALG on specific devices.
