I recently purchased a new 8861 3pcc K9. It is asking for an activation code. I purchased this phone for my small business and I'm the only user. I can NOT figure out how to find this code or get past this. Thanks in advance for your help.

I was able to now get past the activation code prompt. Now, on the display I have my user ID with an X beside it and the line button is lit up in yellow instead of green. Still no dial tone or not able to use it but, can access settings. Any ideas on what might be the issue now? I appreciate your time sir.

I have a CISCO 8861 that requires an activation code. I inserted several codes but I still get the error message "invalid activation code".
I entered the last code on another handset and it took directly, but on the CISCO 8861, it always gave me the error message "invalid activation code".

Did you check the phone model, is it MPP or Enterprise? Please verify that you are using MPP (3PCC) phones in Webex calling. If it is not an MPP phone, then yes you should convert the phone to MPP firmware before you use it in the Webex calling. Please check the following URL to help you with MPP conversion. ( _converter_wxc)

Regarding Webex Calling, you can add a phone either by using its MAC address or activation code. Please confirm that you have configured it in the Webex Control Hub against a user or a workspace with the correct phone model, and then retrieve the activation code and input it again.

Additionally, please ensure that the phone is using MPP firmware and not the enterprise firmware. If you know the IP address of the phone, simply browse the IP and check if the GUI shows MPP firmware. Alternatively, you can verify the product code; if it shows CP-8861-3PCC-K9, it indicates MPP firmware.

Thank you for the answer !
I also tried to add via the MAC address, but no change on the handset, I also performed a factory reset afterwards but nothing changes. It always asks me for the activation code.
Is it absolutely necessary to upgrade the firmware?

Multiple vulnerabilities in the web-based management interface of certain Cisco IP Phones could allow an unauthenticated, remote attacker to execute arbitrary code or cause a denial of service (DoS) condition.

The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit the other vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerability.

A vulnerability in the web-based management interface of Cisco IP Phone 6800, 7800, and 8800 Series Multiplatform Phones could allow an unauthenticated, remote attacker to inject arbitrary commands that are executed with root privileges.

This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system of an affected device.

A vulnerability in the web-based management interface of Cisco IP Phone 6800, 7800, and 8800 Series Multiplatform Phones could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition.

Cisco has released free software updates that address the vulnerabilities described in this advisory. Customers with service contracts that entitle them to regular software updates should obtain security fixes through their usual update channels.

Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license:
-user-license-agreement.html

Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.

The Cisco Support and Downloads page on Cisco.com provides information about licensing and downloads. This page can also display customer device support coverage for customers who use the My Devices tool.

When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page, to determine exposure and a complete upgrade solution.

In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.

Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC: -cisco-worldwide-contacts.html
