I recently bought a new certificate to run our companies phone service. In the mail I received four different certificates:
- Root CA Certificate - AAACertificateServices.crt
- Intermediate CA Certificate - USERTrustRSAAAACA.crt
- Intermediate CA Certificate - SectigoRSA…
- Your COMODO SSL Certificate - pbx_…
I followed these steps:
Certificate Management -> delete old certificate -> Upload Certificate
I upload the private key
In “Certificate” I upload “* Your COMODO SSL Certificate - pbx_…”
In “Trusted Chain” I upload “* Intermediate CA Certificate - USERTrustRSAAAACA.crt”
I press “Generate Certificate”
I choose “apply config”
I choose the new certificate as default
I go to System Admin - HTTPS Setup - Settings - Install Certificate
I go to the UCP and try to make a call. It shows green and a text says “registered” but when I try to make a call nothing really happens.
Is there anything I’m missing here? The phone system worked with the old certificate last week, and I haven’t done any hardware changes since then.
