Looking at documentation guide "Cisco Expressway Certificate Creation and Use " it does not specify what certificate authorities can be used. in previous guides like "webex Telepresence for VCS expressway" it details what Root CA's will work.
Now I know this is more pointed at webex so logistically any cert authority should work as long as the client machine trusts the CA.
Other presentations list that the Cert must be X.509V3 compliant. (attached)
There are also requiremetns for SAN.
is there any one good source for demystifying what is exactly required to deploy expressway core and edge certificates the right way the first time around?
