SIP trunk between Webex Calling and Avaya on-premises

[Rita9741]

Is it possible to create a communication between Avaya systems in branch 1 and Webex Calling in branch 2 using SIP Trunk? 

I can't find much documentations

Yes with the Local Gateway feature implemented on a SIP SBC from Cisco or one of the other supported OEMs.
