Activate / Deactivate Call Waiting

[utongbullet]

How can I activate/deactivate call waiting through code? I initially tried by dialling with the Telephony API but that doesn't work. Looking around for any articles about network service requests but I can't seem to find any. Some help would be appreciated. Thanks.

Hi,

For this I think you need to have access to etelmm.h

I can't find more information about etelmm.h other than it being a restricted header and that I would need to be a partner to use it. Does anyone else have a clearer answer? I only need to enable call waiting, not disable it.

Thanks for the header file. I found EMobilePhoneSetCallWaitingStatus listed as one of the enums in ETELMMCS.H. Could someone point me in the right direction on how to use this? thanks.

Hi,
You can find the relative usage in the etelmm.h . I would suggest you to look into RMobilePhone class (if you have it there since it is an internal class) for related API.

If you do not have access to the Etelmm API, then you could also do the task with AT commands..

RCommServ commServer;
	commServer.Connect();

	_LIT(KCsyName, "dataport");
	User::LeaveIfError(commServer.LoadCommModule(KCsyName));

	_LIT(KDataPort, "DATAPORT::0");
	TBuf<20> port(KDataPort);
	TInt ret= comm.Open(commServer, port, ECommShared);
	if(ret == KErrNone){
		_LIT8(buf8, "ATQ0DT*43#\r\n");
		comm.Write(iStatus, buf8);
	}

Am I doing this right? I found this example and changed the AT command to dial *43#.

a full example for AT command sending could be found from the Wiki: http://wiki.forum.nokia.com/index.ph...T_Commands.zip
