Microsoft Office 365 Exchange UM with Legacy PBX
AudioCodes Mediant Gateway 36 Document #: LTRT-40512
4.13 Configure Certificates
As noted earlier in Section 3 on page 13, communication between the gateway and Office
365 Exchange Online UM requires the use of a digital certificate signed by a Certificate
Authority (CA). The gateway is supplied with a self-signed certificate, which cannot be used
because it is not signed by a supported CA.
Before certificate configuration takes place, ensure that the DNS (see Section 3.2 on
page 13 ) and NTP (see Section 4.2 on page 22) settings have been configured correctly. If
this is the case, proceed as follows.
