RE: CRM Dynamics 365 on premises integration with Avaya
Hi Mohammad,
You have probably found your answer by now, but in case you are still in search for a solution, the easiest way of doing that would be to embed a web application into Dynamics that is capable of consuming Avaya CTI events and also communicate with the CRM system
We at Geomant have created our own API on CRM, which follows the guidelines of Open CTI, and also create our own application, Desktop Connect, that can add Avaya voice functionality into Dynamics CRM (2013, 2016, Online, 365) basically every system starting from 6.0. Desktop Connect, can be consumed as a service from the cloud or installed onpremise.
