Hello
I hope this has not already been answered
We currently have an Avaya IP Office solution and ATT is our phone provider
We have O365 A3
a. With our current setup if we allowed teams to connect via the ATT SBC can we make and receive calls in teams and with our current Avaya Workplace app and our Avaya SIP and H.323 phones or do we have to upgrade to O365 A5?
b. If this is possible what would it take?
i. We are working to implement an E911 solution (red sky or SentryNG911) do these work in a hybrid environment with teams?
ii. How much is the extra cost to use teams exclusively as an E911 solution and does it have to be intrado for teams?
I saw this document

We have about 900 Users
200 capable of using the softphone component in avaya
We have a contract with Avaya for the next three years so we would like a hybrid solution for the time being and when we terminate our avaya contract we would like to move fully to using teams as our PBX
