Table 1: Phone Based Registration Network ports
Note that either HTTP or HTTPS is used on a per customer basis. The choice depends on:
Security requirements, e.g. HTTPS only.
Device support (some older devices do not support HTTPS – refer to the Cisco IP Phone security guide for list of devices that support secure communications.
Certificates for HTTPS¶
When using HTTPS for connectivity the VOSS Automate certificate must be installed on Cisco Call Managers that make use of the Phone Based Registration Service.
The VOSS Automate Platform certificate needs to be copied from the VOSS Automate server and uploaded to CUCM.
Log in to VOSS Automate using Firefox or Chrome. In the URL click on the ‘Lock’ symbol and choose to view the Certificate. Find the ‘Copy To’ or ‘Export’ option depending on your browser and save the certificate file to your PC.
Log in to VOSS Automate using the “Cisco Unified OS Administration” login. Browse to Security > Certificate Management and upload the Certificate with the Certificate Purpose set to ‘tomcat-trust’. Restart the Cisco service as per the instructions.
The CUCM Hostname configured on CUCM under System > Server must be able to resolve via DNS otherwise the Phones will not authenticate. If the Hostname does not resolve then change the hostname to the IP Address instead.
