I need to know the difference between AES TSAPI advance license for small, medium and large switches?
What scale do i need for AVP duplex CM license?and for small AVP S8300 server?

For information on which license is needed for a particular size/type of Communication Manager, you should contact Avaya Client Services or an Avaya Business Partner. They will be able to advise you.

I already tried that with my partner but his reply is not clear can you differentiate between them?

Sorry, I do not know how Voice Portal would impact on the TSAPI Advanced license requirements.

AVP stands for avaya virtual appliance not voice portal.

I still thing that your business partner is the correct channel for this question.

i finally got the info found in the document
Avaya Aura® Application Enablement
Services Overview and Specification


The TSAPI advanced license is intended for applications that launch calls (predictive dialing
applications) or route calls. The TSAPI advanced license is based on the number of
Communication Manager servers you want to license and the size of the Communication Manager
platform: Small (S84xx), Medium (S85xx), and Large (S87xx and S8800).
