Anybody using Namecheap for their domain and certs and having issues with the SIP domain not being valid in IX Workplace when TLS is activated?
From my experience, they don't support addind URI:sip:example.com in the Subject Alternative Name.
If in the CSR, I have stuff like:
commonName = iposrv.example.com
emailAddress = admin@example.com
[v3_req]
keyUsage = nonRepudiation, digitalSignature, keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth, clientAuth
subjectAltName = @alt_names
[alt_names]
DNS.1 = iposrv.example.com
DNS.2 = example.com
URI.1 = sip:mtl-lab.com
When they generate the cert, and I open it with Windows, I see the cert as valid, but now the SAN looks like this:
DNS=iposrv.example.com
DNS=
Why does it automatically add
front of example.com?! Also don't know why they removed DNS:example.com and URI:sip:example.com, so now IX Workplace complains the SIP domain is invalid.
