For the scalability, I rate it a seven out of ten. 

It is a scalable solution.

I have found Cisco TelePresence to be scaleable. We are able to scale up the number of members on a call.

We have eight locations that are using this solution.

Scalability depends on your architecture. Scalability depends on servers as well. If you use any of the bridge communication like Cisco WebEx or something like that which creates a bridge between the end device and the conferencing solution, you can scale it up to any number that the bridge supports. 

Our users are generally SMBs.

TelePresence is scalable. If we want to scale with this kind of deployment we can add a conference in the DMS.
