title: How make use of the Voice API to make calls using Huawei 3g Modems?
body: <p>Some Huawei 3g modems like mine (E1752) has ability to make and receive calls. I believe onboard there is PCM channel that can be used while making or receiving the calls but I do not have any more information on that.</p>
  
  <p>I am using their app called the Mobile Partner which is a fairly complete app which supports making and receiving calls. But I want to build my own app which will run on Mac OS X. But I am not able to locate any documents detailing the Voice API and the onboard PCM channel. If anybody is aware of this please let me know.</p>
