In regards to the EventingConnector, is there a way to setup subscriptions for all extensions at once or do we have to do it for each extension one by one?

There is a user field that is mandatory when filling out a subscription and filling this out for 16,000 extensions can be tedious.

"user (in the filter) Mandatory The address for which you are interested for call events"


Also I just wanted to reaffirm that Breeze can handle 15k Subscriptions per CM, so with 2 CMs, it could do 30k Subscriptions? Our Breeze is using a Medium size profile.

Subscriptions currently have to be done one at a time. Your understanding of capacities is correct.
