In a new deployment, we need VMIVR-IVR-SESS licenses.
When the trial version of this license ended, ivr was unable to worked and answered calls.
After that i have installed this demo license again and the problem solved but i dont know why we need this license.
I just find this explanation but in this deployment we are not using features like email, fax, dn access. I dont know what VXML is.
"You do not need to purchase IVR session licenses if you are only planning on using voicemail and auto attendant with basic IVR applications.
IVR session licenses are only required if your application contains advanced IVR features such as email, fax, database access or VXML scripts.
Is there any answer why we need this license?
