On-premises SBC with Office 365 Exchange UM RRS feed

  • Question

  • I have been seeing a problem with respect to initial tls handshake. The certificate installed on SBC is signed by third party CA(go daddy). SBC initiates tls handshake as there is any incoming call from PBX. Further, there is also sever hello and certificate request from Exchange online. Subsequently, SBC advertises the certificate as well as the key exchange information. However, there is no response further from Exchange after this.

    Has anyone tried this before? or ran in to something similar?
