CUCM Version 10.5 - (Test) License still available?

[Thomas Biesterfeldt]

Hi all, 

I have request from customer who is currently using CUCM version 
10.5. 
I would like to integrate the customer's CUCM into a contact center solution via JTAPI.
For development and testing I need a CUCM version 10.5 license. Is there a possibility to get it - even it's already "out of sale".

Thanks for your support!

Thomas
