Some third-party vendors or IT asset resellers use their own SKUs (stock keeping units) when selling surplus software licenses. “86614” could be an internal inventory code for a “New” (unused) Cisco IP Communicator license pack.

More specifically, the error occurs during the TFTP (Trivial File Transfer Protocol) configuration download phase. The softphone sends its MAC address (or a generated one) to the CUCM. The CUCM looks for a matching device profile. If it doesn’t find one, or if the security credentials mismatch, it throws error 86614.

If you do not have a support contract, the "new" setup file must come from your organization's internal software repository or a trusted archived source.
