what is Route Group in Cucm?

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.

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.

How does Cisco Unified Communications Manager perform digit analysis?

Cisco Unified Communications Manager performs system digit analysis and routing; however, the Cisco Unified IP Phone needs to know when enough digits are collected before call processing takes place, so the administrator configures SIP Dial Rules and adds the SIP dial rule to the phone.

What is calling search space?

A calling search space comprises an ordered list of partitions that users can look at before users are allowed to place a call. Calling search spaces determine the partitions that calling devices, including IP phones, soft phones, and gateways, can search when attempting to complete a call.

How does Cisco Call Manager work?

For call set up, teardown and supplementary service work, CUCM uses SIP or SCCP to communicate with Cisco IP Phones. Use the Real-Time Transport Protocol (RTP) to deliver audio, after a call has been made, media exchange occurs directly between the Cisco IP Phones across the IP network.

What is a Dial Plan Cisco?

Dial plans determine how the digits are interpreted and transmitted. You can use a dial plan to facilitate dialing or to block certain types of calls such as long distance or international. If the Cisco SPA IP phones are part of the Cisco SPA9000, dial plans are configured on the Cisco SPA9000.

What is translation pattern?

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. Translation patterns are processed as Urgent Priority by default in the CUCM call routing database.

What is Digit manipulation?

Digit manipulation is the ability of Cisco Unified Communication Manager to add or remove digits to comply with a specific internal dial or numbering plan used in PSTN. There are multiple ways to perform digit manipulation of the calling party numbers for outgoing call to PSTN.

How do I block a number on Cisco Call Manager?

To block calls in the same manner at the Cisco CallManager level, use translation patterns. To do this, the DNIS or called number can be specified in a route pattern, then applied to the gateway. In this case, the “****” that is used to block the call is the Route or Block this pattern option.

What is trunk in Cucm?
