This document explains how to change the Cisco CallManager IP address with which the Cisco Unity is integrated. The information in this document was created from the devices in a specific lab environment.
You need to change the IP address of the Cisco CallManager through the Cisco Unity Telephony Integration Manager (UTIM). Choose Switch Integration Tools and double-click on Telephone Integration Manager, which opens the UTIM. Service Providers today, such as AT&T, are offering alternative methods to connect to the PSTN via their IP network. Cisco Unified Border Element version 1.4 can perform payload-type value interworking for RFC2833 DTMF packets when the RTP payload-type values are mismatched between the inbound and outbound SIP call legs. Payload Type - prior versions of CISCO UBE required static dial peer configuration to set a payload-type value used for digit passing with RFC2833. This product contains cryptographic features and is subject to UnitedStates and local country laws governing import, export, transfer anduse.
Cisco IOS Software Release 12.2S is designed for Enterprise campus and Service Provider edge networks that require world-class IP and Multiprotocol Label Switching (MPLS) services.
Release 12.2S enable advanced Ethernet LAN switching, Metro Ethernet, and Broadband Aggregation services through enhancements in High Availability, Security, MPLS, VPNs, and IP Routing and Services. Dynamic Multipoint VPN (DMVPN) combines multipoint Generic Routing Encapsulation (mGRE) tunnels, IPsec encryption, and Next Hop Resolution Protocol (NHRP) routing to provide users a streamlined method of configuring large hub-to-spoke IPsec VPNs and enables dynamic discovery of tunnel endpoints. The topology shown in Figure 1 and the corresponding bullets explain how this feature works. VPN Routing and Forwarding (VRF) Instance Integrated Dynamic Multipoint VPN (DMVPN) enables users to map site-to-site DMVPN IPsec sessions into Multiprotocol Label Switching (MPLS) VPNs. It is not uncommon to situate a remote DMVPN spoke behind a NAT box, where a Port Address Translation (PAT) is enabled. Figure 3 illustrates that it is typical for spokes in a DMVPN cloud to be given the same physical address by the NAT boxes sitting in front of them. Dynamic Multipoint VPN (DMVPN) Spoke-to-Spoke Functionality allows dynamic on-demand direct spoke-to-spoke tunnels to be created between two DMVPN spoke CPEs without traversing the hub.
Cisco IOS Software headends that terminate SafeNet clients need to be able to support multiple groups of SafeNet clients using different wildcard preshared keys. Key Rollover for Certificate Renewal provides Policy Based Routing for IPv6 equivalent to IPv4.
Port Security with Sticky MAC Address converts dynamically learned MAC addresses to configured addresses automatically. SPAN Destination Port Permit List allows configuring a list of ports that are allowed to be SPAN destination ports. As IP traffic continues its explosive growth across today's networks, enterprise and service providers must be able to characterize this traffic and account for how and where it flows.
The challenge, however, is finding a scalable, manageable, and reliable solution to provide the necessary data to support these opportunities. In addition to measurement and billing, NetFlow also performs strategic analysis on their point-of-presence (POP) traffic for network planning, acceptable usage policy enforcement, or service-level management (SLM). Cisco has developed a robust ecosystem of NetFlow partners who have developed value-add functionality and reporting specialties, including accounting, traffic analysis, security, billing, network planning, and network monitoring.
This needs to be done if you migrate the IP address of a Cisco CallManager with an existing Cisco Unity integration and needs to continue with the same integration.


Most of these services utilize SIP as the primary signaling method and a centralized IP to TDM gateway to provide on-net and off-net services. The configuration described in this document details the important commands for successful interoperability. This component may be a H323, SIP or MGCP gateway, the protocol is optional and the choice is left up to the customer's network design. The Cisco Unified Border Element can be configured to fallback to a legacy PSTN connection (e.g. Please review the AT&T IP Flexible Reach Service Guide in detail to understand these limitations and restrictions. This feature allows users to configure a single multipoint GRE tunnel interface, a single IPsec profile, and no crypto access lists on the hub router to handle all spoke routers. Thus, this feature allows IPsec to be immediately triggered for the point-to-point GRE tunneling or when the GRE peer address is resolved via NHRP for the multipoint GRE tunnel. This feature allows spoke routers to have dynamic physical interface IP addresses (common for cable and DSL connections). This allows service providers to extend their existing MPLS VPN service by mapping off-net sites (typically a branch office) to their respective VPNs. When the DMVPN spokes need to send a packet to a destination (private) subnet behind another spoke, they query the Next Hop Resolution Protocol (NHRP) server for the real (outside) address of the destination spoke. As the spokes often times have no control over the addresses provided to them by the ISP, DMVPN was enhanced to work for spokes behind a NAT Box. This feature enables production-ready spoke-to-spoke functionality in single- and multi-hub environments in a DMVPN network. This leads to reduced latency and jitter for spoke-to-spoke traffic and improved bandwidth utilization.
As a result, all spoke-to-spoke traffic traversing the hub and requiring a dual encrypt and decrypt for all traffic putting an additional burden on the hub CPU. Each key is placed in a keyring, which is bound to a specific interface address, so that the headend knows which key the client may be using. The intended use of this feature is as a safeguard to prevent the accidental misconfiguration of a port.
This presents business opportunities that help justify and optimize the vast investment involved in building a network, ranging from traffic engineering (to optimize traffic flow through the network) and understanding network detailed behavior.
This information allows planning and allocation of network and application resources, including extensive near real-time network monitoring capabilities. NetFlow services data optimizes network planning, which includes peering, backbone upgrade planning, and routing policy planning. Changes in network behavior indicate anomalies that are clearly demonstrated in NetFlow data.
Customers can, therefore, use NetFlow to track IP traffic flowing into or out of their server farms for capacity planning or to implement usage-based billing.
It enables the accumulation of data on flows with unique characteristics, such as IP addresses, application, and CoS. Users can leverage Cisco NetFlow collector as a flow collector, or they can opt for a variety of third-party partner products. If your network is live, make sure that you understand the potential impact of any command. AT&T IP FlexReach is a service provider offering that allows connection to the PSTN and may offer the end customer a viable alternative to traditional PSTN connectivity via either analog or T1 lines.


Care must be taken by the network administrator deploying CISCO UBE to ensure these commands are set per each dial-peer required, to interoperate to AT&T SIP network. Deploying Fax over G.711 will require specific dial peer configurations that apply to the fax GW and Cisco Unified Border Element. Each spoke registers its real address when it boots and queries the NHRP database for real addresses of the destination spokes in order to build direct tunnels. Thus, the size of the configuration on the hub router remains constant even if spoke routers are added to the network.
IPsec sessions are terminated on the DMVPN PE device and traffic is placed in VRFs for MPLS VPN connectivity. The DMVPN hub maintains a NHRP database of the tunnel endpoints and the physical address of the spokes.
It also incorporates increased spoke-to-spoke resiliency and redundancy in multi-hub configurations. DMVPN networks deliver a lower cost per MByte of Bandwidth than native IPsec networks because the spoke-to-spoke traffic is not restricted by hub bandwidth utilization and at the same time it does not add any additional overhead to the hub bandwidth utilization. Understanding behavior allows customers to implement new IP Services and applications with confidence. NetFlow allows extremely granular and accurate traffic measurements and high-level aggregated traffic collection. It minimizes the total cost of network operations while maximizing network performance, capacity, and reliability. The data is also a valuable forensic tool to understand and replay the history of security incidents. A Graphical user interface displays and analyzes NetFlow data collected from FlowCollector files.
Specifically, work was done to extend the Next Hop Routing Protocol (NHRP) to look into the VRF Tables while building the database of spoke addresses in the hub. Because it is part of Cisco IOS Software, NetFlow enables Cisco product-based networks to perform IP traffic flow analysis without purchasing external probes--making traffic analysis economical on large IP networks. NetFlow provides proactive problem detection, efficient troubleshooting, and rapid problem resolution. NetFlow detects unwanted WAN traffic, validates bandwidth and Quality of Service (QoS), and enables the analysis of new network applications. NetFlow supports key technologies, including IPv4, IPv6, Multicast, and Multiprotocol Label Switching (MPLS). This allows users to complete near-real-time visualization or trending analysis of recorded and aggregated flow data.
The Cisco Unified Border Element provides demarcation, security, interworking and session management services.
This information is used to efficiently allocate network resources and to detect and resolve potential security and policy violations.
