Chapter 19 Cisco Voice Messaging,What s New in This Chapter. This chapter presents a high level design discussion and is focused on how the voice messaging products. fit into a collaboration system with Unified CM For detailed design guidelines for each product as well. as interoperability information for third party messaging and telephony systems refer to the Cisco Unity. Connection design guides available at, http www cisco com en US products ps6509 products implementation design guides list html. What s New in This Chapter, Table 19 1 lists the topics that are new in this chapter or that have changed significantly from previous. releases of this document, Table 19 1 New or Changed Information Since the Previous Release of This Document.

Cisco Unified Enhanced Survivable Remote Site Various sections throughout this chapter November 19 2013. Telephony E SRST,Voice Messaging Portfolio, The Cisco Unified Communications messaging portfolio consists of two main messaging products. Cisco Unity Connection and Cisco Unity Express Each product fits different requirements yet each one. contains overlapping features and scalability with regard to the others They also have the ability to. interwork with one another using Voice Mail Networking to achieve voicemail interoperability as well. as higher scalability as discussed later in this chapter. When considering these products it helps to think of the messaging types that the products apply to in. order to understand the messaging options they include and to determine which options could fit your. deployment requirements The following definitions help describe these messaging types. Voicemail only refers to a telephony voicemail integration where there is no access to the voicemail. via any messaging client, Integrated messaging refers to voicemail with telephony access as well as voicemail only access via. a messaging client, Unified messaging refers to voicemail with telephony access as well as voicemail email and fax.
access via a messaging client, Table 19 2 shows which Cisco products support these types of messaging. Cisco Collaboration System 10 x SRND,19 2 OL 30952 03.

Voicemail only Yes Yes,Integrated messaging Yes Yes. Unified messaging Yes No, Note For further details on Unified Messaging with Cisco Unity Connection see Single Inbox with Cisco.
Unity Connection page 19 43, Based on the above messaging types and definitions the two messaging product options are. Cisco Unity Connection, This option combines unified and integrated messaging voice recognition and call transfer rules. into an easy to manage system for medium sized businesses with up to 20 000 users In addition. multiple Cisco Unity Connection clusters can be joined using a digital or HTTPS network system. Additionally if required two HTTPS or digital network systems can be joined using Voice Profile. for Internet Mail VPIM networking to support more than 100 000 users Cisco Unity Connection. can support up to 100 000 users in a digital network or HTTPS network Cisco Unity Connection is. also available with Cisco Business Edition Cisco Business Edition 6000 supports up to a maximum. of 1 000 users With Cisco Business Edition 7000 the normal Cisco Unity Connection capacity. planning rules apply For more information on Cisco Business Edition see Design Considerations. for Call Processing page 9 30,Cisco Unity Express, This option provides cost effective voice and integrated messaging automated attendant and. interactive voice response IVR capabilities in certain Cisco Integrated Services Routers for small. and medium sized businesses and enterprise branch offices with up to 500 users. For a complete comparison of product feature refer to the Cisco Messaging Products Feature. Comparison available at, http www cisco com en US products sw voicesw ps2237 products data sheets list html. For more information on scalability of voice messaging products refer to the section on Voice. Messaging page 27 41 in the chapter on Collaboration Solution Sizing Guidance page 27 1. This chapter focuses on the design aspects of integrating Cisco Unity Connection and Cisco Unity. Express with Cisco Unified Communications Manager Unified CM Cisco Unified CM provides. functionality for Session Initiation Protocol SIP trunks which support integration directly to Cisco. Unity Connection without the need for a SIP proxy server. For information on earlier releases of Cisco Unity Connection Unity Express and Unified CM or. Unified CM Express refer to the appropriate online product documentation available at. http www cisco com, As mentioned the design topics covered in this chapter apply to voicemail only unified messaging and.
integrated messaging configurations Additionally this chapter discusses design aspects of deploying. Cisco Unity Connection with Microsoft Exchange 2003 2007 or 2010 Cisco Unity Connection and. Unity Express have no dependencies on an external message store. Cisco Collaboration System 10 x SRND,OL 30952 03 19 3. Chapter 19 Cisco Voice Messaging,Messaging Deployment Models. For additional design information about Cisco Unity Connection including integrations with other. non Cisco messaging systems refer to the Design Guide for Cisco Unity Connection available at. http www cisco com en US products ps6509 products implementation design guides list html. For additional design information about Cisco Unity Express including integrations with other. non Cisco messaging systems refer to the applicable product documentation available at. http www cisco com en US products sw voicesw ps5520 index html. Messaging Deployment Models, This section summarizes the various messaging deployment models for Cisco Unity Connection and. Cisco Unity Express For a complete discussion of the deployment models and design considerations. specific to Cisco Unity Connection and the various messaging components refer to the Design Guide. for Cisco Unity Connection available at, http www cisco com en US products ps6509 products implementation design guides list html. For Cisco Unity Express refer to the applicable product documentation available at. http www cisco com en US products sw voicesw ps5520 index html. Cisco Unity Connection supports three primary messaging deployment models. Single site messaging,Multisite deployment with centralized messaging.
Multisite deployment with distributed messaging, Cisco Unity Express also supports three primary messaging deployment models. Single site messaging,Multisite deployment with distributed messaging. Multisite deployment with distributed messaging with Cisco Unified CME. Note The Cisco Unity Express supports centralized voice messaging for up to 10 Unified CMEs For more. information refer to the Cisco Unified Communications Manager Express documentation at. http www cisco com en US products sw voicesw ps4625 index html. Although the call processing deployment models for Cisco Unified CM and Unified CME are. independent of the messaging deployment models for Cisco Unity Connection and Unity Express each. has implications toward the other that must be considered. Cisco Unity Connection messaging redundancy is available in an active active configuration For more. information refer to the Design Guide for Cisco Unity Connection available at. http www cisco com en US products ps6509 products implementation design guides list html. All messaging deployment models support voicemail integrated messaging and unified messaging. installations,Cisco Collaboration System 10 x SRND. 19 4 OL 30952 03,Chapter 19 Cisco Voice Messaging,Messaging Deployment Models. Single Site Messaging, In this model the messaging systems and messaging infrastructure components are all located at the.
same site on the same highly available LAN The site can be either a single site or a campus site. interconnected via high speed metropolitan area networks MANs All clients of the messaging system. are also located at the single or campus site The key distinguishing feature of this model is that there. are no remote clients,Centralized Messaging, In this model similar to the single site model all the messaging system and messaging infrastructure. components are located at the same site The site can be one physical site or a campus site interconnected. via high speed MANs However unlike the single site model centralized messaging clients can be. located both locally and remotely,Distributed Messaging. A distributed messaging model consists of multiple single site messaging systems distributed with a. common messaging backbone There can be multiple locations each with its own messaging system and. messaging infrastructure components All client access is local to each messaging system and the. messaging systems share a messaging backbone that spans all locations Message delivery from the. distributed messaging systems occurs via the messaging backbone through a full mesh or hub and spoke. type of message routing infrastructure, Distributed messaging is essentially multiple single site messaging models with a common messaging. backbone The exception to this rule is the PBX IP Media Gateway PIMG and T1 IP Media Gateway. TIMG integrations PIMG and TIMG integrations are not discussed in this design document For. further information regarding PIMG or TIMG refer to the Cisco Unity Connection integration guides. available at, http www cisco com en US products ps6509 index html. The distributed messaging model has the same design criteria as centralized messaging with regard to. local and remote GUI clients TRaP and message downloads.

Centralized messaging and distributed call processing Yes No1. Distributed messaging and distributed call processing Yes Yes. Centralized messaging with cluster over the WAN Yes No. Distributed messaging with cluster over the WAN Yes Yes. 1 Support for centralized voicemail messaging with Unified CME is available with Cisco Unity Express however this is not. applicable to Unified CM call processing deployment models. This section covers the following topics, Cisco Unity Connection messaging and Unified CM deployment models. Cisco Unity Express deployment models, Each topic defines a messaging and Unified CM deployment model combination and then highlights.
each Cisco voicemail messaging product applicable to that model as well as the design considerations. for that model combination Not all combinations are discussed for each product Some examples are. provided with best practices and design considerations for each product The intention is to provide an. understanding of the base messaging deployment models and the interaction with Unified CM without. detailing all possibilities, For further details on site classification and a detailed analysis of supported combinations of messaging. and call processing deployment models refer to the Design Guide for Cisco Unity Connection available. http www cisco com en US products ps6509 products implementation design guides list html. Cisco Collaboration System 10 x SRND,19 6 OL 30952 03. Chapter 19 Cisco Voice Messaging, Messaging and Unified CM Deployment Model Combinations. Cisco Unity Connection Messaging and Unified CM Deployment Models. This section discusses some of the various combinations of messaging and call processing deployment. models for Cisco Unity Connection, Centralized Messaging and Centralized Call Processing. In centralized messaging the voice messaging server is located in the same site as the Unified CM. cluster With centralized call processing subscribers may be located either remotely and or locally to the. cluster and messaging server s See Figure 19 1 When remote users access resources at the central. site such as voice ports IP phones or PSTN gateways as in Tail End Hop Off TEHO these calls are. transparent to gatekeeper call admission control Therefore regions and locations must be configured .
