My company is prepare to deploy a Voice IP system on CME with CUE 2.3. We was leased an E1 line with 30 channels and bought a Cisco 2821 for this job. I just have a little theory and no experience about this solusion so i need a task list step-by-step to deploy such as E1 parameter for ISP do,power infrastructure (with grouding), dial plan, tftp profiles for IP Phones...which have to do first. Could anyone who has experienced share the task list or templates for me? Thanks in advance!
