Call Hold is not working

[rahulkrv]

When request to hold the call, it terminates the call
// holds or resumes the call

public sipToggleHoldResume() {
try {
if (this.oSipSessionCall) {

    var i_ret;

    this.callInfo['message'] = this.oSipSessionCall.bHeld ? 'Resuming the call...'
      : 'Holding the call...';
    console.log(this.oSipSessionCall)

    i_ret = this.oSipSessionCall.bHeld ? this.oSipSessionCall.resume()
      : this.oSipSessionCall.hold();

    this.callInfo['message'] = this.oSipSessionCall.bHeld ? 'Hold' : 'Unhold';

    if (i_ret != 0) {
      this.callInfo['message'] = 'Hold / Resume failed';
    }

  }
} catch (e) {
  console.log("error hold", e)
}

}

Any work on this? Looks like the project is abandoned about 3 years.
