Is It possible to change the default sip firmware on cp-7811 to multiplatform firmware upgrade so we can use it with 3rd party platform

Conversion from Enterprise to 3PCC is now available but it's no longer free (unless you have a Flex subscription for WebEx Calling):  Cisco Cloud Upgrader

This path (Enterprise to MPP) was never free, because it was just made available recently with this migration program.

The path that was free (with the initial MPP releases) was only one way, and it was MPP to Enterprise. There was no Enterprise to MPP at that time.
