Ready the Data Center for an SBM Deployment
Communicate Information to the SBM Administrator
■ Either:
• A .pfx certificate/private key file
Certificate filename: _______________________
Private key password: ______________________
• Instructions on how the certificate should be requested:
– Generate a request manually
– Request a certificate automatically
Credentials for the user who requests the certificate only the CA
administrator has decided that the SBM administrator will
generate the certificate in this way:
Username: ___________________________________
Password: ___________________________________
■ Optionally, CA certificate chain file
This file is required if your domain does not use group policy objects
(GPOs) to push the CA certificate to domain computers.
Filename: ___________________________________________
■ Information about SIP trunking:
• The SBM is using SIP trunking only.
• The SBM is using SIP trunking with one or more backup PSTN
connections.
• The SBM is not using SIP trunking.
If the SBM is using SIP trunking only, then you do not need to communi-
cate the rest of the information, which applies to the Media Gateway
settings.
■ Transport protocol for the Media Gateway, either:
• TLS (recommended)
• TCP
This is the protocol that the gateway uses to listen for communications
from the Lync solution.
■ Local listening port for the Media Gateway only if it is not standard
Non-standard listening port: ____________________________
This is the listening port that the CS Administrator defined for the PSTN
gateway when adding the SBM as a survivable branch appliance. Figure A-
46 shows the default ports for TCP and TLS marked with 1.
