Configure Call Control Discovery
The call control discovery feature leverages the Service Advertisement Framework (SAF) network service, a proprietary Cisco service, to facilitate dynamic provisioning of inter-call agent information. By adopting the SAF network service, the call control discovery feature allows Cisco Unified Communications Manager to advertise itself along with other key attributes, such as directory number patterns that are configured in Cisco Unified Communications Manager Administration, so other call control entities that also use SAF network can use the advertised information to dynamically configure and adapt their routing behaviors; likewise, all entities that use SAF advertise the directory number patterns that they own along with other key information, so other remote call-control entities can learn the information and adapt the routing behavior of the call. The following procedure configures the call control discovery feature in your network.
Procedure
Step 1 |
If you have not already done so, configure the Cisco IOS router as the SAF forwarder. See the documentation that supports your Cisco IOS router; for example, see the Cisco IOS Service Advertisement Framework Configuration Guide or the Cisco IOS Service Advertisement Framework Command Reference. Cisco Feature Navigator allows you to determine which Cisco IOS and Catalyst OS software images support a specific software release, feature set, or platform. To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn . |
||
Step 2 |
Configure the SAF security profile for the SAF forwarder ( ).You can configure more than one SAF security profile in Cisco Unified Communications Manager Administration. A SAF forwarder, which is a Cisco IOS router that you configured for SAF, handles the publishing requests for the local Cisco Unified Communications Manager cluster and the service advertisements from remote call-control entities. |
||
Step 3 |
Configure the SAF forwarders in Cisco Unified Communications Manager Administration ( ). Cisco recommends that you configure a primary and backup SAF forwarder for failover support. |
||
Step 4 |
Configure SAF-enabled SIP and/or H.323 intercluster (non-gatekeeper controlled) trunks ( ).The local Cisco Unified Communications Manager cluster uses SAF-enabled trunks that are assigned to the CCD requesting service to route outbound calls to remote call-control entities that use the SAF network. The Cisco Unified Communications Manager cluster advertises the SAF-enabled trunks that are assigned to the CCD advertising service along with the range of hosted DNs; therefore, when a user from a remote call-control entity makes an inbound call to a learned pattern on this Cisco Unified Communications Manager, this Cisco Unified Communications Manager receives the inbound call from this SAF-enabled trunk and routes the call to the correct DN. |
||
Step 5 |
Configure the Hosted DN groups. Cisco recommends that you group the hosted DN patterns by location; for example, hosted DN patterns that represent different zip codes for a city may get grouped together. ( ).Hosted DN groups are a collection of hosted DN patterns that you group together in Cisco Unified Communications Manager Administration. You assign a hosted DN group to a CCD advertising service in Cisco Unified Communications Manager Administration, and the CCD advertising service publishes all the hosted DN patterns that are a part of the hosted DN group. You can only assign one Hosted DN group to one call control discovery advertising service. |
||
Step 6 |
Configure the Hosted DN patterns. ( ).Hosted directory number (DN) patterns are patterns that represent directory numbers that belong to a call-control entity; for example, hosted DN patterns that you configure in Cisco Unified Communications Manager Administration are a range of directory numbers that belong to the local Cisco Unified Communications Manager cluster that you want to advertise to remote call-control entities. The CCD advertising service publishes the hosted DN patterns to the active SAF forwarder. |
||
Step 7 |
To publish the hosted DNs for the local Cisco Unified Communications Manager cluster, configure the Call Control Discovery Advertising service. ( ). You can configure as many CCD advertising services as you want. The call control discovery advertising service, which resides in Cisco Unified Communications Manager, allows the local Cisco Unified Communications Manager cluster to advertise its hosted DNs and the PSTN failover configuration to the remote call-control entities that use the SAF network. |
||
Step 8 |
Configure a partition that is used specifically for call control discovery. ( ).
|
||
Step 9 |
To ensure that the local Cisco Unified Communications Manager cluster can listen for advertisements from the SAF network, configure one call control discovery requesting service. ( ). You can only configure one CCD requesting service. The call control discovery requesting service, which resides in the local Cisco Unified Communications Manager, allows the local Cisco Unified Communications Manager to listen for hosted DN advertisements from remote call-control entities that use the SAF network. |
||
Step 10 |
If you have not already done so, configure your remote call-control entity to use the SAF network; for example, configure Cisco Unified Communications Manager Express or other Cisco Unified Communications Manager clusters for the SAF network. |
||
Step 11 |
After you configure call control discovery, you may block learned patterns that remote call-control entities send to the local Cisco Unified Communications Manager. ( ). |
