Abstract

Methods, systems, and computer program products for establishing transcoding free connections between UMA and UMTS call legs are disclosed. According to one method, a media gateway determines whether codec configurations used by UMA and UMTS legs of a call are compatible. In response to determining that the configurations are compatible, media gateway determines whether rate control is necessary to establish a transcoding free connection. In response to determining that rate control is necessary, the media gateway issues rate control requests on the UMA and UMTS legs as appropriate. The media gateway determines whether the rate control requests are successful. In response to determining that the requests are successful, the media gateway establishes a transcoding free connection between the UMA and the UMTS legs of the call.
