SAP PI 7.31 single stack to call web service using TLS 1.2

Hello folks,

I have been met with the requirement to call a web service using TLS 1.2. We are on a single stack 7.31 SP16. I am using a SOAP receiver channel.

The guys exposing the web service tell me that I am using TLS 1.0 (extract from their log:  TLSv1 AES256-SHA ... )

Does SAP PI 7.31 SP16 not support TLS 1.2 when calling a web service or do I need to make some changes or maybe use HTTP Axis protocol?

Hope you can help

Regards, Mikael
