Dear Fabio I am using call Observer for handling GSM call events with AO and calling hold/unhold/Hangup with help of ETel API, I used the following code in RunL(), { CTelephony::TCallStatus status = iCallStatus.iStatus; switch (status) { case CTelephony::EStatusRinging: { Call_Hold();// function call for call hold } break; case CTelephony::EStatusDialling: { Call_Hold(); break; case CTelephony::EStatusAnswering: { symbian_ua_endcall(); // call hangup } break; case CTelephony::EStatusConnected: { symbian_ua_endcall(); } break; case CTelephony::EStatusIdle: { // for checking there should be any hold call // if no call it well show ?No current Call? pjsua_call_reinvite(call_id, PJ_TRUE, NULL); // function call for call unhold } break; default: { break; } } I want to achieve call waiting like beep tone during Ringing event rather than holding the call, please guide me.

But please provide your experience in handling such things. Technically speaking you need to write an Inbound Voice Call Observer, that connect to the Etel Server, receive incoming call notification, and pause PJSIP.
