Chapter 2 Deployment Models
IPT: Single Site
This system can be installed using the traditional Unified CCE model (not Unified System CCE), which
would allow for several different options. For example, two Unified CCE System PGs could be installed
along with a single Unified CVP.

Unified System CCE or traditional Unified CCE must be deployed in a redundant fashion. Simplex
deployments are supported only for lab or non-production deployments. For information on Unified
CCE redundancy, see to the chapter on

type of voice gateways, or the number of voice gateways and trunks. Cisco campus design guides and
Cisco Unified Communications design guides are available to assist in the design of these components.

Another variation in this model is to have the voice gateways connected to the line side of a PBX instead
of the PSTN. Connection to multiple PSTNs and a PBX all from the same single-site deployment is also
possible. For example, a deployment can have trunks from a local PSTN, a toll-free PSTN, and a
traditional PBX/ACD. For more information, see

This deployment model also does not specify the type of signaling (ISDN, MF, R1, and so on) to be used
between the PSTN and voice gateway or the specific signaling (H.323 or MGCP) to be used between the
voice gateway and Unified CM.

The amount of digital signal processor (DSP) resources required for placing calls on hold, consultative
transfers, and conferencing is also not specified in this model. For information on sizing of these
resources, refer to the latest version of the Cisco Unified Communications Solution Reference Network

The main advantage of the single-site deployment model is that there is no WAN connectivity required.
Given that there is no WAN in this deployment model, there is generally no need to use G.729 or any
other compressed Real-Time Transport Protocol (RTP) stream, so transcoding would not be required.

Unified CCE: Unified CCE System PG
In this deployment model, the agent PG that is deployed is a Unified CCE System PG. Only a single
peripheral is needed to handle both the Unified CM and any Unified IP IVRs that may exist. This
peripheral unifies the appearances of the multiple PIMs and also handles load balancing calls between
multiple Unified IP IVRs. Alternatively, this model may be configured to use Unified CVP. When
Unified CVP is used, its connectivity to Cisco Unified Presence handles load balancing by distributing
the incoming calls among Unified CVP Call Servers. In this deployment, the VRU PIMs (up to 10)
communicating with the Unified CVP Call Server(s) reside on their own PG and not under the
Unified CCE System PG.
