Expressway E and C TLS connection failed

asmlicense

Hello Cisco world,

I am trying to build a connection between E and C, but the sip connection fails. Corporate has internal (ex. test.local) and external (ex. test.com) domain. And according to domains, internal and external DNS. I also have Microsoft CA. 

Expressway C hostname: expc.test.com

Expressway E hostname: expe.test.com

Trusted CA certificates are valid in both E and C with test.local. 

in Generate CSR for EXPe, I include only "Unified CM registrations domains" as test.com.

in Generate CSR for EXPc, I include nothing. There is just FQDN. 

I can upload server sertificates certificates successfully, but tls connection is not active.

Hi,

Can you verify the certificate requirements as per the following guide ( page 15 onwards )

I have gone through the official document of expressway 8.6. It was almost the same which you suggested.

By the way, OpenSSL works.
