Refer to Cisco IOS Telephony Services Version 2.1 for more information on ITS and Cisco IOS Software releases.Ĭisco 3725 Gateway with Cisco IOS Software Release 12.3(4)T with the IP Plus feature set is used in the configuration example, although most IAD 2400s, 1700, 2600, 2800, 3600, 3700, 3800 series routers are currently applicable. This document assumes Cisco IOS Telephone Services (ITS) 2.0 support in Cisco IOS Software Release 12.2(8)T or later. The information in this document is based on these software and hardware versions:Ĭisco IOS® Software Release 12.2(8)T or later with a minimum of IP Plus (IP/VOX Plus on the Cisco 1700 series) feature set. Cisco IOS Telephony Service version 3.0 is referred to as CallManager Express 3.0.

Prerequisites Requirementsīefore you attempt this configuration, ensure that you are familiar with how to configure a Cisco IOS Telephony Service on a router. This document provides examples of how to configure COR.
This means that if there is no COR configuration for incoming calls on a dial-peer, then you can make a call from this dial-peer (a phone attached to this dial-peer) going out of any other dial-peer, irrespective of the COR configuration on that dial-peer. Similarly, if you make a call to that FXS phone, then it is an outgoing call.īy default, an incoming call leg has the highest COR priority and the outgoing COR list has the lowest COR priority. Keys are assigned to dial peers with an incoming COR list.įor example, if you hook up a phone to one of the Foreign Exchange Station (FXS) ports of the router and try to make a call from that phone, it is an incoming call for the router/voice-port. Locks are assigned to dial peers with an outgoing COR list. COR is often described as a lock and key mechanism. Incoming and outgoing are terms used with respect to the "voice ports". If the COR applied on an incoming dial-peer (for incoming calls) is a super set or equal to the COR applied to the outgoing dial-peer (for outgoing calls), the call goes through. This functionality provides flexibility in network design, allows users to block calls (for example, calls to 900 numbers), and applies different restrictions to call attempts from different originators. COR functionality provides the ability to deny certain call attempts on the basis of the incoming and outgoing CORs that are provisioned on the dial-peers. The corlist command sets the dial-peer COR parameter for dial-peers and the directory numbers that are created for Cisco IP phones associated with the Cisco CallManager Express router. Each dial-peer can be provisioned with an incoming and an outgoing COR list. COR is required only when you want to restrict the ability of some phones to make certain types of calls but allow other phones to place those calls.ĬOR is used to specify which incoming dial-peer can use which outgoing dial-peer to make a call. The COR feature provides the ability to deny certain call attempts based on the incoming and outgoing CORs provisioned on the dial-peers. It is most commonly used with Cisco Survivable Remote Site Telephony (SRST) and Cisco CallManager Express but can be applied to any dial peer.
Class of Restrictions (COR) is a Cisco voice gateway feature that enables Class of Service (COS) or calling privileges to be assigned.
