Cisco Unified Communications (Call Manager) WAN Design

Greetings/Good Morning/Dobra Den, Urgent assistance required in the initial design and planning for rolling out Cisco Call Manager over a WAN from central office to 4 remote sites. Call Manager V.7 already installed in central office, initially need advice on office setup to prepare for rollout and remote site integration. WAN will be by VSAT so bandwidth optimisation critical, design stage of WAN network almost complete which includes remote site interconnection via microwave links. Will finalise satellite bandwidth requirements after receiving your input on Cisco requirements. Initially a list of questions to ask the administrator/local supplier in order to glean the required current configuration to initiate design. Possibility later of actual hands on by remote access during implementation stage. Network schematics are available should you wish to be involved. Payment terms flexible as you wish, hourly or milestone based. Although I have broad experience in RF systems, VSAT's and TDMA PABX's, assistance required on Call Manager - appreciate you help and involvement.. Looking forward to hearing from you.
