Hi Jurik,
Thanks for the fix and update, code looks correct to me just a simple typo mistake.
/* ApplyFilter(AGC, NoiseReduce, EchoCancel, AAGC, CN) */
/* Set all vars on 0 */
var AGC = 0;
var NoiseReduce = 0;
var EchoCancel = 0;
var AAGC = 0;
var CN = 0;
/* if-clauses for all checkboxes */
if (document.IaxVoicePhoneCtrl.chknoise.checked)
NoiseReduce = 1;
if (document.IaxVoicePhoneCtrl.chkagc.checked)
AGC = 1;
if (document.IaxVoicePhoneCtrl.chkcn.checked)
CN = 1;
if (document.IaxVoicePhoneCtrl.chkaagc.checked)
AAGC = 1;
/* call function ApplyFilter with declared vars */
iaxWebPhone.ApplyFilter(AGC,NoiseReduce,EchoCancel,AAGC,CN);
