August 1, 2022, was end of Add-on/Expansion sales (ie. licensing)... This would fall in that category... I don't think what you are wanting to do is viable. The existing system will run as is until the end of license date, but MiVoice Call Recording is a dead product. I have another larger customer in a similar situation... we have yet to come up with a viable solution as their phone system is discontinued as well.
Mitel Interaction Recording is the official replacement platform for this... but if you are migrating away it might not be a viable solution either.
