In Cisco Unified Communications Manager Administration, use the Call Routing > Route/Hunt > Route Pattern menu path to configure route patterns. A route pattern comprises a string of digits (an address) and a set of associated digit manipulations that route calls to a route list or a gateway.

What is SIP route pattern?

Cisco Unified Communications Manager uses SIP route patterns to route or block both internal and external calls. The domain name or IP address provides the basis for routing. This method allows requests that are destined for these domains to be routed through particular SIP trunk interfaces.

What is a CUCM route group?

A route group allows you to designate the order in which gateways and trunks are selected. It allows you to prioritize a list of gateways and ports for outgoing trunk selection.

How does Cisco Unified Communications Manager determine which pattern to use?

When the Cisco CallManager encounters a dialed number that matches multiple route patterns, it uses closest-match routing to determine which route pattern most closely matches the number and directs the call using that route pattern.

What is the difference between route pattern and translation pattern?

The primary difference between route patterns and translation patterns is that translation patterns do not have a final path selection destination (route list, gateway, or trunk). Translation patterns exist only to manipulate digits; they do not perform call routing.

What is LRG in Cucm?

The Local Route Group feature helps reduce the complexity and maintenance efforts of provisioning in a centralized Cisco Unified Communications Manager deployment that uses a large number of locations.

How do I create a translation pattern in Cucm?

To configure a translation pattern, navigate to Call Routing > Translation Pattern, as shown in Figure 12-12. The translation pattern identifies the dialed digit string to match and the calling- or called-party transformation settings that should be applied.

What is a device pool in Cucm?

A device pool is configured with a name and a CUCM group. It includes roaming-sensitive settings and Device Mobility-related settings configured under Device Mobility Related Information.

How does Cucm digit analysis?

CUCM performs digit-by-digit analysis from a SCCP (Skinny Client Control Protocol) controlled phone. As soon as 911 is received, the call will be routed before the final 2 can be dialed. Normally, an overlapping dial plan entry will result in a 15 second wait before the call is routed.

What are translation patterns in Cucm?

Translation Patterns in CUCM are very similar to Route Patterns, but they do not have a Call Routing destination. Route Patterns point to Route Lists or gateways, while translation patterns are used to manipulate digits. Translation patterns are used to Block calls in the Line/Device Cisco Class of Service approach.

What is the difference between translation and transformation in Cucm?

Translation patterns can be configured in the Cisco Unified Communications Manager to manipulate digits for any type of call. Transformation patterns are configured when the calling or called number needs to be changed before the system sends it to the phone or the PSTN.

What is CSS Cucm?

In Cisco Unified Communications Manager Administration, use the Call Routing > Class of Control > Calling Search Space menu path to configure calling search spaces (CSS). A calling search space comprises an ordered list of route partitions that are typically assigned to devices.
