Communications Server 2010 voice policies define the following for each user, site, or organization that is assigned the policy:
- A set of calling features that can be enabled or disabled to
determine the Enterprise Voice functionality available to users
- A set of PSTN usage records that define the call permissions
Planning for Voice Policies
To plan the voice policies you will need for your Enterprise Voice deployment:
- Determine how you will configure your default Global voice
policy. This policy will apply to all Enterprise Voice users who
are not explicitly assigned a site-level or per-user 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.
- Determine what PSTN usage records to configure for each voice
Voice Policy Scope
Voice policy scope determines the hierarchical level at which the policy can be applied. In Communications Server 2010, you can configure voice policies with the following scope levels (listed from the most specific to the most general).
- User voice policy: can be assigned to individual users,
groups, or contact objects. This is the lowest level policy. Note
that for the purpose of assigning a voice policy, a contact object
is treated as an individual user.
- Site voice policy: applies to an entire site, except for
any users, groups, or contact objects that are assigned a User
voice. To define a Site voice policy, you must specify the site to
which the policy applies. If a User voice policy is not assigned,
the Site default is used.
- Global voice policy: is the default voice policy
installed with the product. You can edit the Global voice policy to
meet the specific needs of your organization, but you cannot rename
or delete it. This voice policy applies to all Enterprise Voice
users, groups, and contact objects in your deployment unless you
configure and assign a voice policy with more specific scope. If
you wish to disable this policy entirely, make sure that all sites
and users have custom policies assigned to them.
You can enable or disable the following call features for each voice policy:
- 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 on hold and then
pick up the call from a different phone or client. Disabled by
- Simultaneous ringing enables incoming calls to ring on
additional phones (for example, a cell 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 re-route enables calls made by users who are
assigned this policy to other enterprise users to be re-routed 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 (such as bomb threats) using the client UI, and that in turn
flags the calls in the call detail records (CDR). Disabled by
PSTN Usage Records
Each voice policy must have one or more associated PSTN usage records. For information about planning PSTN usage records, see PSTN Usage Records.
|PSTN usage order is critical because in matching users to routes, the server compares PSTN usages from top to bottom. If the first usage matches the call route, that route is used. If not, the server looks at the next PSTN usage on the list and continues until a match is found. In effect, the subsequent PSTN usages provide backup in the event the first one on the list is unavailable.
