However, using CheckAppLic for UC, voicemail and other licenses did not work for me. The response for UC, voicemail and other UC-related licenses was always "ok: false" in my case. I have tried various variations for the "lic" parameter (e.g. "Voicemail", starting with a capital letter), but that didn't work either. The same request works for licenses such as "App(softphone)" though.

Request:

{"api":"PbxAdminApi","mt":"CheckAppLic","cn":"admin","lic":"voicemail","src":"foobar"}

Response:

{"api":"PbxAdminApi","src":"foobar","mt":"CheckAppLicResult","ok":false}
