Access to RisPort on CUCM 11.x

I used to access the RisPort service on a CUCM 10.x at the address https://@ip/realtimeservice/services/RisPort

But on a CUCM 11.x (11.0.1.20000-2) this address does not work (HTTP Status 500).

So how to access to RisPort service on a CUCM 11.x ?

The RisPort WSDL is deprecated. Use the RisPort70 WSDL and the following address format:

https://<ip>:8443/realtimeservice2/services/RISService70

Thank you for the answer. The Risport is deprecated since which version? The RisService70 is available since which version?

It looks like the switch began with CUCM 9.x, when developers were encouraged to use RisPort70 because RisPort would eventually be deprecated.  They were fully deprecated as of version 11. 

RisPort70 first appeared in CUCM 7.0, I believe
