right now I'm doing this but it doesnot work.
`call = phoneNo => {
if (!this.isRegistered()) return;
this.oConfigCall.display_name = '54321';
if (this.oSipStack && !this.oSipSessionCall) {
this.oSipSessionCall = this.oSipStack.newSession('call-audio', this.oConfigCall);
if (this.oSipSessionCall.call(phoneNo) !== 0) {
this.oSipSessionCall = null;
}
} else if (this.oSipSessionCall) {
this.oSipSessionCall.accept(this.oConfigCall);
}
};`
Can someone help me?
