Frequently Asked Questions

Is the Cisco 7945G compatible with Cisco Webex Calling?

The Cisco 7945G is a legacy CUCM phone and is not natively supported on Cisco Webex Calling. For Webex Calling deployments, consider newer Cisco IP Phone 8800 or 9800 series models.

Yes — the Cisco 7945G supports both SCCP (Skinny Client Control Protocol) and SIP, providing flexibility for different Cisco UC platform configurations.

What is the difference between the 7945G and 7965G?

The 7965G offers 6 line keys compared to the 7945G's 2 lines, and includes additional programmable buttons — making the 7965G better suited for users managing multiple lines or shared call appearances.
