ETel Core can be used to produce a simple telephony application. It handles placing of a call, answering a 
call and ending a call. It does not use GSM specific information such as signal strength and network 
name. The functions of the ETel Core API which are supported are listed below:

The P800 and P900 series do not use the standard Symbian MMS API. 

The steps described below are documented in the UIQ SDK. It is important that the developer is familiar 
with the “Aifbuilder” and “MakeSIS” tools which are used for preparing applications to execute on the 
mobile phones. 

Each Symbian OS UI variant has a shell program that allows the user to run application programs. For an 
application to be run from such a shell program, at least two files are needed: 

Class RCall
(functionality associated with a 
specific call)

Class RLine
(functionality associated with a 
specific line)

Class RPhone
(functionality associated with a 
specific phone)
