The subjects we need to cover with enterprise voice are the following:
- Dial Plans
Pool dial plan: Can be created at the service level for any PSTN gateway or Registrar in your topology. To define a pool dial plan, you must specify the particular service (PSTN gateway or Registrar pool) to which the dial plan applies.
Site dial plan: Can be created for an entire site except for any users, groups, or contact objects that are assigned a pool dial plan or user dial plan. To define a site dial plan, you must specify the site to which the dial plan applies.
Global dial plan: Is the default dial plan installed with the product. You can edit the global dial plan, but you cannot delete it. This dial plan applies to all Enterprise Voice users, groups, and contact objects in your deployment unless you configure and assign a dial plan with more specific scope.
- Voice Policy
Identify any site-level voice policies you might need.
Identify any per-user voice policies you might need.
Decide which call features to enable for each voice policy.Here a list of call features:
- Call forwarding enables users to forward calls to other phones and client devices. Enabled by default.
- Delegation enables users to specify other users to send and receive calls on their behalf. Enabled by default.
- Call transfer enables users to transfer calls to other users. Enabled by default.
- Call park enables users to park calls and then pick up the call from a different phone or client. Disabled by default.
- Simultaneous ringing enables incoming calls to ring on an additional phone (for example, a mobile phone) or other endpoint devices. Enabled by default.
- Team call enables users on a defined team to answer calls for other members of the team. Enabled by default.
- PSTN reroute enables calls made by users who are assigned this policy to other enterprise users to be rerouted on the public switched telephone network (PSTN) if the WAN is congested or unavailable. Enabled by default.
- Bandwidth policy override enables administrators to override call admission control policy decisions for a particular user. Disabled by default.
- Malicious call tracing enables users to report malicious calls by using the Microsoft Lync 2010 client, and then flags such calls in the call detail records. Disabled by default
