Best Practices

The following are best practices from this chapter:

• Collocate Mediation Servers with a Front End Server when possible to reduce the hardware requirements for each deployment.

• Create multiple trunk associations between different pools to the same gateway for additional resiliency.

• Carefully follow the steps provided by a Survivable Branch Appliance vendor before placing the SBA in service.

• Use a unique dial plan for each location that has different dialing habits.

• Use translation rules on a trunk configuration only if the opposite end of the trunk is not manipulating digits.

• Configure the required network objects before attempting Call Admission Control, Media Bypass, or E911 setup.

• Use test cases to verify an Enterprise Voice configuration before publishing changes.

• Use a Survivable Branch Appliance or Survivable Branch Server in each remote office without a resilient WAN connection to the central site.

• Plan a Response Group workflow with diagram tools before attempting to create the workflow.
