Product overview

Cisco® Unified Customer Voice Portal (Unified CVP) helps businesses and organizations deliver a connected digital experience, enabling you to deliver contextual, continuous, and capability-rich journeys for your customers across time and channels. This award-winning product provides IP-based self‑service and call routing. It combines open-standards support for speech with intelligent application development and industry-best call control to deliver personalized self-service to callers, either as a standalone Interactive-Voice-Response (IVR) system or transparently integrated with a contact center.

Business value

With Unified CVP, businesses and organizations can provide incoming callers with automated, intelligent self-service using touch-tone input or speech recognition. Callers can access and modify their accounts, place orders, get status updates, retrieve information, and resolve problems, all without speaking to a live agent. This paradigm results in dramatic savings in agent costs. However, if an agent's services are required, Unified CVP can queue the call and then transfer it to an agent, along with information about the caller and the self‑service session. With this solution agent, productivity improves, and customers enjoy a smooth service experience.

Unified CVP is an IP-based system, but it easily interoperates with traditional telephony networks through voice gateways. The architecture of Unified CVP provides distributed call treatment with centralized application management, allowing calls to receive self-service and queuing at the most efficient (or desirable) location, while still enabling consistent branding and caller experience and easy application updates.

When self-service or queuing is complete, Unified CVP uses Session Initiation Protocol (SIP)-based call control to instruct the network where to route the call, potentially reducing or eliminating telephony carrier transfer costs. The ability of Unified CVP to route calls across customer service sites enables resource virtualization, allowing businesses and organizations to lower their costs significantly by reducing the number of agents required to maintain a given service level. For example, a customer might call a local office and if no agents are free, Unified CVP can easily route the call to a different site where an agent is available.

Unified CVP is especially powerful when used as part of the broader portfolio of Cisco Unified Communications solutions because it takes full advantage of the superior capabilities of Cisco routers and Session Border Controllers (SBCs).

Streaming audio is also supported (with Real-Time Streaming Protocol [RTSP]) when using the Cisco IOS® Gateway VoiceXML browser, allowing play of live audio sources.

Collect caller input

Unified CVP can collect information from callers in a variety of ways (for example, yes or no, menu choices, forms, and data types), enabling faster, more intuitive self-service sessions.

Barge and type ahead

Knowledgeable callers can save time by skipping through prompts and announcements they are already familiar with.

Opt out

Callers have the option to press zero to speak with a live agent.

G.729 codec

Support for this audio codec helps ensure that network bandwidth is used more efficiently.

Post-call surveys

Support for caller surveys following the self-service session enhances customer satisfaction and provides valuable feedback to the business or organization.

Courtesy callback

Callers in queue can request a call back when an agent becomes available, reducing time spent on hold and lowering caller frustration.

Speech (Automatic Speech Recognition [ASR] and text-to-speech [TTS])

  ASR and TTS are optionally supported through Nuance, providing a faster, more intuitive self‑service session.
  Media Resource Control Protocol (MRCP) Version 2 is supported, allowing support for optional, advanced speech-based features. For additional information, visit the Cisco Developer Network at:

Video contact center

Unified CVP supports audio-based self-service and queuing for calls, which optionally become video calls when routed to a contact center agent. This support provides rich caller-agent interactions while saving costs and bandwidth during the self-service portion of the call.

Video in queue

The Unified CVP video-in-queue feature allows a video caller on Cisco Unified Communications Manager (UCM) to view a High-Definition (HD) video prompt and navigate a video menu using Dual-Tone Multi-Frequency (DTMF) keys while in queue for a video agent. This feature allows businesses and organizations to provide personalized, high-touch services to customers at remote and branch-office sites such as a local bank office or a retail store.

Note: Video-in-queue functionality with Unified CVP is supported only for existing Cisco MediaSense customers on the Cisco IOS®-based VoiceXML gateway. For a list of supported video endpoints, consult the latest hardware and system software specification for Unified CVP at:

Cisco Virtual Expert Management

For additional information, visit:



Unified CVP supports integration with email servers to send email messages based on caller self-service input, allowing callers to benefit from this additional service channel.

Short Message Service (SMS)

Unified CVP supports integration with SMS servers to send messages based on caller self-service input, allowing callers to benefit from this additional service channel.

Basic outbound

Built-in outbound functions enable Unified CVP to make an outbound call from a polled data file, providing simple outbound functions without the complexity and expense of a complete solution.

Outbound with Cisco Unified Contact Center Enterprise

If full outbound functions are required, Unified CVP can be deployed with the Cisco Unified Contact Center Enterprise Outbound option.

Call control and CTI

Transfer to agent, IVR, Private Branch Exchange (PBX), Automatic Call Distributor (ACD), or carrier network

In addition to its self-service and queuing capabilities, Unified CVP possesses powerful SIP-based call control to instruct the IP network where to route the call. This control can include call transfer to an agent, IVR, ACD, PBX, or a carrier network, providing a wealth of customer service options. Cisco professional services and authorized Cisco Advanced Technology Partners can assist with integrations to specific devices and carrier networks.

Bridge transfer

Unified CVP can bridge transfer calls to an alternate number in case the primary number for an agent is not reachable or if no response is received from remote PBX. The original call is maintained on the bridge and the alternate number dialed by the application. When the call is answered, the caller will be bridged to a remote agent. The caller can always press the termination character to come out of the current call and dial another secondary number without disconnecting the initial call.

Computer Telephony Integration (CTI)

Unified CVP can transfer the call to an agent along with CTI information about the caller and the caller’s self-service session. This feature improves agent productivity and results in a smoother customer service experience. CTI data can be passed through either Cisco Unified Intelligent Contact Management (ICM) or directly to SIP-enabled devices through the SIP message header.

Carrier interoperability

Testing and certification have been performed with Unified CVP and the following telephony carrier-call transfer mechanisms:

  Two B-Channel Transfer (TBCT)
  ATT's IP Trunking

Session Initiation Protocol (SIP)

  Information about the call and caller can be provided to the agent in the SIP header, speeding problem resolution.
  Support for Cisco Unified SIP Proxy improves solution redundancy by enabling dynamic reroute around an endpoint that is down.
  Unified CVP supports SIP trunks with mu-law and A-law encoding.
  Unified CVP supports SIP trunks with TLS.
  Unified CVP supports a range of SIP RFCs to enable powerful, comprehensive, and efficient control over calls. Some of the major RFCs supported include:

    RFC 3261: Session Initiation Protocol (SIP)

    RFC 3811: SIP UPDATE method (Unified CVP receives and responds)

    RFC 3515: SIP REFER method (Unified CVP sends)

    RFC 3891: SIP REPLACE method (no special handling)

Dynamic routing

Unified CVP can route calls based on trunk group and endpoint availability, improving call-completion rates and providing trunk reporting.

Location-Based Call Admission Control (LBCAC)

LBCAC enables you to control the audio quality and video quality of calls over a wide area network (IP WAN) link by limiting the number of calls that are allowed on that location at the same time. Enhanced LBCAC bandwidth calculations are more accurate, and the feature can now select a local VoiceXML gateway for Voice-Response-Unit (VRU) treatment at the branch office during warm transfers from an agent.

Agent greeting

A configurable, automated agent greeting can be played to callers, standardizing the caller experience. The agent greeting helps to keep agents’ voices fresh by saving them from having to repeat the same greeting on every call.

Agent whisper

A configurable announcement can be played to an agent right before the caller is connected, providing information about the type of call being delivered (for example, "sales" or "tech support") and other guidance. This feature gives agents information about the caller, speeding problem handling and improving first-call resolution.

MicroApp integration

MicroApps created with the Cisco Unified Contact Center Enterprise (UCCE) script editor are integrated with the CVP VoiceXML server. This process consumes a VoiceXML server port during MicroApp execution.



Unified CVP is extremely scalable, supporting deployments from as small as 24 ports (a single T1) to as large as 15,000 ports. The CVP Java Virtual Machine uses a 64-bit architecture, enabling Unified CVP to support up to 3000 calls per virtual machine.

VoiceXML browsers

Unified CVP uses a server-based Virtualized Voice Browser (VVB), allowing it to play announcements, collect information, and queue calls using open-standards VoiceXML. VVBs can be deployed essentially anywhere on the network, allowing self-service and queuing to occur at the most efficient and cost-effective location. Unified CVP can also use the VoiceXML browser built into certain Cisco IOS voice gateways, although this support is gradually being phased out in favor of the VVB. The CVP port license includes entitlement for either the VVB or the Cisco IOS Voice Browser. Customers can currently use both the VVB and the Cisco IOS Voice Browser in the same deployment.

VVB on a Kernel-Based Virtual Machine (KVM)

Cisco VVB is supported on the Kernel-Based Virtual Machine (KVM) that is available natively on Cisco 4000 Series Integrated Service Routers. This allows a small-to-medium-sized edge deployment to use the VVB natively on the router hardware by removing the need to host an add-on Cisco UCS-E module. For more information, visit:

Load-balancer support

Unified CVP supports Citrix NetScaler and other third-party load balancers that meet defined criteria to provide load distribution and high availability with resources such as speech-recognition servers. For more detailed interoperability information, visit: or consult the latest CVP design guide at:

Cisco Unified Computing System (Cisco UCS®) server support

  The cost per server is lower with Unified CVP.
  Virtual-machine co-residency allows server consolidation, reducing power, rack space, and cooling requirements.

Cisco ASR 1000 Aggregation Services Router support

The router consolidates the Unified CVP voice browser with other network functions on a single server, reducing hardware and support requirements.

Virtual CUBE (Cisco Cloud Service router)

Unified CVP is certified with the virtual Cisco Unified Border Element (vCUBE), enabling a broader range of deployment options and making it possible for businesses to deploy Unified CVP with less router hardware. For more information, visit: and the Compatibility Matrix for your solution at:

Secure Hash Algorithm 256 (SHA 256) security

CVP supports SHA 256 Secure Sockets Layer (SSL) certificates that significantly improve solution security.

Network queuing

The ability of the application to treat and queue calls on network gateways helps businesses and organizations achieve higher customer service levels by virtualizing resources across multiple sites. For example, a customer might call the local Boston office and if no agents are free, Unified CVP can easily route the call to a different site where an agent is available.

Network-based recording

You can use Cisco Unified Border Element (CUBE) and Cisco Unified Communications Manager with Unified CVP to enable network-based recording of calls.


The distributed architecture of the application provides robust failover capabilities. For example, if a network gateway is taken out of service, subsequent calls can be immediately routed to a different gateway for treatment.

VMware support

Support for VMware and a co-resident Peripheral Gateway (PG) provides more Unified CVP deployment options on fewer boxes. VMware ESXi 5.5, 6, and 6.5 are supported.

System compatibility

  Unified CVP and Cisco Unified Contact Center Enterprise (UCCE) support IPv6 endpoints in dual-network mode, enabling easier migration from IPv4.
  Windows 2012 and Informix 12.10 (for CVP reporting server) are supported.

Simplified configuration and administration

Representational-State-Transfer (REST) APIs for service fulfillment (for example, media files and VoiceXML scripts) and service assurance (such as syslog configurations and Simple Network Management Protocol [SNMP] alerts) provide easy manageability of VoiceXML applications and media files across the network and simplify the configuration of syslog and SNMP alerts. Unified CVP service assurance APIs support SNMP Version 3.


Reporting database

A built-in reporting database enables businesses and organizations to create their own Unified CVP reports using third-party tools.

Cisco Unified Intelligence Center

Customers can optionally purchase Cisco Unified Intelligence Center with Unified CVP to create customizable reports that show a holistic view of their customer interactions.
