Hosting Cisco Call Manager and Unity Connection

I have a customer who wants me to host their Cisco Call Manager and Unity Connection in my datacenter, because they don't want it on site anymore.  I have experience setting up on premise VOIP for customers, but not hosted.  I do host a lot of other applications for them in the datacenter, but a hosted Cisco VOIP solution is one of them.  If I entertain this idea, does Cisco offer a multi-tenent Call Manager and Cisco Unity Connection solution, where I could potentially host call manger and unity for multiple customers/businesses on the same server?   Essentially like a new instance for each business?  Let me know.  thanks.

I agree with that benefit, but one Callmanager system is totally capable of handling a multitenant design. The links I provided show how Cisco has already though of this and validates the design to comply so that Service Providers can get proper support from TAC.

I guess you can install Callmanager and Unity outside those boundaries, I just don't know very well how would the support be handled by TAC engineers, I mean, not sure if the Cisco Representative will get difficult when selling you the support contract.

A solution, yes:

A special edition of Communications Manager and/or Unity Connection, no.

However, this is what it says in the link:

 Hosted Multi-tenant Unified Communications Services
This model allows service providers to host all the equipment in their data center with virtual partitioning to support multiple tenants. Typically a router, switch, and phones are the only equipment located with the customer, with all calls traveling over a bundled broadband or WAN connection from the service provider.

Check the topology in the admin guide:

Sounds about right?

So if I'm understanding correctly, which I don't know that I am:)  I really couldn't have multiple businesses on the same CUCM and Unity Connection Servers right?  I have a customer who wanted us to host their CUCM and Unity Connection server, because the hardware they have onsite is EOL.  This does not seem cost effective to the customer, if each customer has to have their own CUCM and Unity Connection server in the hosted environment.  The only benefit would be it that the servers are not at their location anymore and they are not responsible for them.  Would you agree?
