Lync 2010 Voice Routing (Part II)

Create Lync 2010 Voice Policies

To Create a Voice Policy:

Open a browser window, and enter the Admin URL to open the Lync Control Panel. In the left navigation bar, click Voice Routing and then click Voice Policy.
On the Voice Policy page, click New and select a scope for the new policy:
- Site policy applies to an entire site, except any users or groups that are assigned to a user policy. If you select Site for a policy scope, choose the site from the Select a Site dialog box. The site does not appear in the Select a Site dialog box if a voice policy has already been created for a site.
- User policy can be applied to specified users or groups.
If the voice policy scope is User, enter a name for the policy in the Name field.
(Optional) Enter additional descriptive information for the voice policy.
To enable or disable each of the Calling features for this voice policy, select or clear the following check boxes:
- 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 default.
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 (CDRs). Disabled by default.

Create a Lync 2010 Voice Route:

Open a browser window, and enter the Admin URL to open the Lync Control Panel.
In the left navigation bar, click Voice Routing.
Click the Route tab.
Click New to display the New Voice Route dialog box.
In the Name field, type in a name for the voice route.
(Optional) In the Description field, type in additional descriptive information for the voice route.
To specify the patterns you want this route to accommodate, you can use either the Build a pattern to match tool to generate a regular expression, or manually write the regular expression.

To use the Build a pattern to match tool to generate a regular expression, enter values as follows. You can specify two types of pattern matching:
1. Starting digits for numbers that you want to allow: Enter prefix values that this route must accommodate (including the leading + if needed). For example, type +320 and then click Add. Repeat this for each prefix value that you want to include in the route.
2. Exceptions: If you want to state one or more exceptions for a prefix value, highlight the prefix and click Exceptions. Type in one or more values for the matching patterns that you do not want this route to accommodate. For example, to exclude numbers starting with +320237 from the route, enter a value of +320237 in the Exceptions field and then click OK.
To manually define the matching pattern, click Edit in the Build a pattern to match tool and type in a .NET Framework regular expression to indicate the matching pattern for destination phone numbers to the applied route. More information about how to write regular expressions is available through ".NET Framework Regular Expressions" at http://go.MS.com/fwlink/?LinkId=140927.

If you do not want the ID of the phone making the outbound call to appear to the call recipient, select Suppress caller ID. If this option is selected, you must specify an Alternate caller ID that will appear on the recipient’s caller ID display.
To associate one or more PSTN gateways or SIP trunks with the voice route, click Add and select a gateway or SIP trunk from the list.
To associate one or more PSTN usage records with the voice route, click Select and choose a record from the list of PSTN usage records that have been defined for your Enterprise Voice deployment.
For optimum performance, arrange the PSTN usage records. To change a record’s position in the list, highlight the record name and click the up or down arrow.
(Optional) Type a value into the Enter a translated number to test field and click Go. The test results are displayed under the field.
Click OK to save the voice route.

Lync 2010 Trunk Media Bypass

To Configure Media Bypass on a Trunk:

Log on to the computer as a member of the RTCUniversalServerAdmins group, or as a member of the CsVoiceAdministrator, CsServerAdministrator, or CsAdministrator role. Open a browser window, and enter the Admin URL to open the Lync Control Panel.
In the left navigation bar, click Voice Routing and click Trunk Configuration.
On the Trunk Configuration page, use one of the following methods to configure a trunk:

Double-click an existing trunk (for example, the Global trunk) to display the Edit Trunk Configuration dialog box.
Click New, and select a scope for the new trunk:

Site trunk: Choose the site for this trunk configuration from the Select a Site dialog box, and then click OK. If a trunk has already been created for a site, the site does not appear in the Select a Site dialog box.
Pool trunk: Choose the service for this trunk configuration (for example, a PSTN gateway at a specified site) from the Select a Service dialog box, and then click OK. If a trunk has already been created for a service, the service does not appear in the Select a Service dialog box.

Give a value in the Maximum early dialogs supported box. This is the maximum number of forked responses a PSTN gateway, IP-PBX, or ITSP Session Border Controller can receive to an INVITE that it sent to the Mediation Server. The default value is 20.
Select one of the following Encryption support level options:

Required: To help protect traffic between the Mediation Server and the gateway or PBX, secure real-time transport protocol (SRTP) encryption must be used.
Optional: SRTP encryption will be used if the service provider or equipment manufacturer supports it.
Not Supported: SRTP encryption is not supported by the service provider or equipment manufacturer and therefore will not be used.

If you want media to bypass the Mediation Server for processing by the trunk peer, select the Enable media bypass check box.
Select the Centralized media processing check box if there is a well-known media termination point (for example, a PSTN gateway where the media termination has the same IP as the signaling termination). Deselect this check box if the trunk does not have a well-known media termination point.
If the trunk peer supports receiving SIP REFER requests from the Mediation Server, select the Enable refer support check box. Deselect the check box if the trunk peer does not support receiving SIP REFER requests from the Mediation Server.
(Optional) Associate and configure translation rules for the trunk:

To choose one or more rules from a list of all translation rules available in your Enterprise Voice deployment, click Select. In Select Translation Rules, click the rules that you want to associate with the trunk and then click OK.
To define a new translation rule and associate it with the trunk, click New.
To edit a translation rule that is already associated with the trunk, click the rule name and then click Show details.
To copy an existing translation rule to use as a starting point for defining a new rule, click the rule name and click Copy, and then click Paste.
To remove a translation rule from the trunk, highlight the rule name and click Remove.

Make sure the trunk’s translation rules are arranged in the correct order. Highlight the rule name and then click the up or down arrow to change a rule’s position in the list.
Click OK when you are finished configuring the trunk.
On the Trunk Configuration page, click Commit, and then click Commit all.
