Abstract

In one aspect of the invention, a method for call transferring in a communication system includes establishing a first call connection between a mobile station and a first telephonic device. The mobile station is operable to communicate with a first client, and the first telephonic device is operable to communicate with a second client. The first client is operable to communicate with the second client. The method also includes placing the first telephonic device on hold, and establishing an alerting call connection between the mobile station and a second telephonic device. The second telephonic device is operable to communicate with a third client, and the third client is operable to communicate with the first and second clients. The method further includes instructing the first client to produce ring back tone for the mobile station, and transferring the first telephonic device to the second telephonic device.
