Does Multi-Tenant Edition Support Call Centers?

Our Multi-Tenant edition is not able to support Call Centers for a few reasons:

1. Thrashing Databases causes stress
2. It will be complicated to know whose data is whose
3. Call Centers can cause huge resource spikes e.g. Call ALL and Call Recording, that inside an Multi-Tenant might be fatal and certainly unmovable
4. Call Centers often need to access the database for items such as setting up Click2Dial, Pop-up, Data Synching. To do that in the Multi-Tenant is not sustainable
