The SDK contains some abbreviations which are not explained anywhere. Could someone please specify what the following abbreviations mean?

* AMM
* ACS
* UCCP
* WCS

Context often helps in this situation as many acroynms have multiple expansions.
AMM might be Avaya Meetings Manager
ACS might be Avaya Client Servcices

For context please check the link I added in the post (https://www.devconnectprogram.com/site/global/products_resources/avaya_client_sdk/programming_docs/current/javascript/communication/tech/configuring_the_sdk.gsp)
