The Importance of an Open, Interoperable Approach
• CPE, in which the customer owns and manages the hardware and software
• Managed CPE services, in which the customer owns the solution, but the service provider manages it
• Fully hosted unified communications, in which the service provider hosts dedicated equipment within its network operations center (NOC) for a predictable monthly cost
• CaaS, or managed cloud services, in which the service provider or system integrator maintains and owns the software, which is delivered over the cloud, and the customer pays a license fee to use it
• Hybrid or blended model, that has a mix of on-premises and managed services
Which Deployment Option Is Right for Your Business?
• If your company views technology as a competitive differentiator: The traditional CPE model is ideal for you if technology is a strategic part of your value proposition and you want to do handle everything yourself. You purchase and integrate the tools and build the knowledge, skills, and processes to manage your converged network and the new unified communications and collaboration solutions that run on it. Your IT staff, in essence, becomes a service provider for your organization.
• If your company wants to focus less on IT and more on core competencies: Managed CPE is something you should consider if you want to own the unified communications infrastructure and software, but you want your IT staff to be able to take on other strategic initiatives, or your IT staff is lacking the required expertise. A service provider with unified communications and collaboration expertise can help you transform your organization and lower your OpEx because the service provider manages the hardware and software. This arrangement eliminates on-premises management and maintenance costs such as full-time help desk and server support, freeing your IT staff to focus on other tasks.
• If your company in a hurry and is risk averse: Fully hosted unified communications may be the deployment model for you if you want to build competitive advantage with leading unified communications and collaboration technologies fast, but you are unsure that your IT staff can handle an enterprisewide initiative. You'll have all the benefits of unified communications with none of the capital outlays and IT support (Figure 3).
When the service provider purchases and hosts dedicated hardware and software, you can take full advantage of the benefits of unified communications without the upfront capital equipment and licensing costs of installing the applications on site. Your service provider handles it all. You have to deal with only one supplier, one bill, and one help desk for your telephony and unified communications needs.
Hosted unified communications also mitigates risk and allows you to concentrate on differentiating your core business from your competitors'. All these benefits are provided for a predictable per-user, per-month fee that becomes a standard business expense.

• If your company is CapEx-constrained and uncertain about the future: Consider CaaS if, like many companies today, you need to do more with less: fewer people, less budget, and less lead time. A software-based delivery model provides unified communications and collaboration services through private clouds. Cloud services deliver rapid time-to-value and are typically paid for as they are used - some providers bill by the second - and you pay for only the required capacity and features. This utility-based pricing model eliminates the cost of directly buying, installing, and maintaining the needed hardware and software (Figure 4).
With CaaS, your company can quickly scale the benefits of unified communications and collaboration across the enterprise and then scale down, depending on your needs, all without your having to manage the infrastructure. CaaS, or managed cloud services, offers the potential to provide the same level of support for converged applications as a CPE solution. CaaS is also a green deployment model, not only because collaboration technologies reduce travel, but also because your company will not be increasing its carbon footprint.
One potential drawback to the CAAS model is that the service provider determines the capabilities, so you may not have all the features available to you that you would if you owned and managed the system yourself. However, if you work with a systems integrator, you can have input into functions.

• If your company is seeking investment protection and flexibility: A blended or hybrid model may be your best option if you have older private branch exchange (PBX) and IP equipment and want to introduce new unified communications and collaboration capabilities without introducing more complexity for your IT staff. With an open and interoperable platform, you can use cloud and premises benefits for particular components. Blended models also help ensure state-of-the-art capabilities because solution providers typically use the most current versions of software and hardware.
You can integrate standalone applications across departments (federation) even if other departments have different deployment models. You can deploy some applications on premises and some in the cloud, working together (application integration), You can also take functions of the same applications and deploy some in cloud and some on your premises (componentization); for example, presence federation can be enabled between on-premises and cloud-delivered unified communications (Figure 5). More important, you can evolve your blended deployment model as your needs evolve and change or as new collaboration technologies become available.
