Description

UACSTA, short for User Agent Computer Supported Telecommunications Application, standardizes a very powerful and flexible set of application services to observe and control voice and non-voice media calls as well as control and observe non-call related features. It is not supported on all models or phone providers.

Below is the original question from customer:

This is possible and supported by some VoIP phone providers, but we have been unable to find uaCSTA in the Yealink phones. May I know if yealink support uaCSTA?


Resolution
