Appendix B: Enterprise Voice Planning Checklist

Communications Server 2007

 

Determine the number and distribution of users.

 

Select your deployment option: PBX integration, departmental, greenfield, or remote user.

 

For PBX integration, make sure that your IP-PBX is either enabled for Enterprise Voice or can be enabled through a software upgrade from the vendor. (If you have a TDM PBX, you cannot implement PBX integration.)

 

For departmental deployment, decide whether to deploy Communications Server in front of or behind your existing PBX.

 

Select type of Media Gateway to deploy: basic, basic hybrid, or advanced.

 

Determine where to locate gateways.

 

Determine size and number of gateways that will be required.

 

If you choose to deploy the Basic Media Gateway, plan hardware requirements for Mediation Server. (Note: If you implement PBX integration, you must deploy a Mediation Server between Communications Server and your PBX.)

 

Determine what normalization rules will be required to translate PBX dial plans into Enterprise Voice Location Profiles.

 

Analyze the various call authorizations currently used by your organization and plan how to convert them to Phone Usage Records.

 

Analyze required call routes for your organization and plan how to convert them to Enterprise Voice Routes.

 

Determine which users will be moved from the existing PBX to the Enterprise Voice infrastructure.

 

Plan how to normalize user primary phone numbers in Active Directory.

 

Determine which administrators will deploy and configure Exchange 2007 Unified Messaging.

 

Determine whether Exchange 2007 UM will be deployed in the same or a different forest as Communications Server 2007.

 

Obtain valid phone numbers for users, subscriber access, and auto-attendant.
