Unified Communication Consultant providing Office Communications Server 2007 (R2) architecture, design, migration strategy, integration and implementation (contract services) for various Microsoft Enterprise Partner's to their client base.
- Implementation and configuration planning for 64-bit hardware conversion and technical guidance with direct SIP Trunking configuration from OCS to existing Cisco Call Manager, (versions 6.5 and 7.1), PBX infrastructure. Custom implementations (based on specific Customer requirements) allowed for client computers to make phone calls world-wide, leveraging OCS Normalization rules and current VOIP infrastructure for SIP-TDM conversion telephone calling. Engagements included deployment of the OCS R2 features and functionality (including voice and video services) to securely extend beyond the corporate network boundaries across the internet using PKI. Internal infrastructure planning also included the corporate network device configurations required to optimize voice and video traffic, queuing and prioritization based on specific packet marker values; therefore standardizing on available network bandwidth for voice and video connections. Result: The custom configurations allowed the desktop computer and the desktop VOIP phone to share the same telephone number, without changing the established telephone operation procedures. Outbound calling could be made from the computer's Communicator client and inbound calls would continue to ring the desktop phone and voice-mail. Custom integration also provided OCSR2 new management functionality of dial-in (internal) numbers used to bridge audio for external Conference participant invited to attend. The custom integration of OCS R2 within established Cisco environments produced:
o extension of Active Directory to enable end-user, feature and functionality for OCS and other Presence-aware systems within the Customer's environment;
o scalable architectures with next-steps for growth across the enterprise;
o well-defined administrative roles between IT and Telecom operations teams;
o immediate cost savings, by leveraging internally hosted resources instead of using externally hosted services (based on typical hosting, cost-per-instance model).
Messaging Solutions Architect
Exchange 2010 Migration Consultant providing messaging architecture, design, migration strategy, integration and implementation (contract services) for various Microsoft Enterprise Partner's to their client base.
- Cross-Forest migration planning and configuration to converge multiple Exchange Organizations for growing, global enterprise. Existing and proposed corporate acquisitions require that IT move forward with Windows Forest consolidation. The overall effort was divided into application, account and workstation work-streams to collapse three separate Source forest's into a fourth, Target forest. I built the new redundant Exchange 2010 infrastructure with DB fail-over and hardware load-balancing of multiple Exchange 2010 servers running identical roles. The system configuration off-loaded both internal and external SSL connections from Exchange servers to the HLB device. Because of budgetary constraints, leveraged ADMT 3.0 tool and PowerShell scripting to create move-requests of mailboxes from Exchange 2007 and Exchange 2003 organizations to the Target Exchange 2010 Organization. The user migration process leveraged input files with associated Active Directory parameters to manage and control the number of users migrated to a specified schedule. Result: Worked with IT team to create migration processes that required high degree of manual intervention and coordination to off-set project constraints. Used batch processing to move mailboxes and .pst files, Server-to-Server to mitigating impact to end-users, WAN utilization, and business continuity during critical financial processing time of the year. The customized migration steps resulted in the least amount of impact with the following Project requirements:
o end-users retained existing SMTP addresses after messaging consolidation;
o mobile device synchronization maintained during cross-forest transition;
o accommodated Customer project requirements to use no 3rd party, automated migration tools (only free, Microsoft utilities);
o accommodated Customer requirements with a solution minimizing impact to Wide Area links during year-end financial processing.
