Abstract
A method for a call control node (MSC-S) for setting up transmission of voice data from a calling party (BSC) towards a called party (BSC) via at least one media gateway node (MGW-, MGW-) is provided, said call control node (MSC-S) acting as a terminating call control node being adapted for communicating with the at least one media gateway node (MGW-) and with an originating call control node (MSC-S), the method comprising receiving first information from the originating call control node (MSC-S) indicative of at least one media gateway node (MGW-, MGW-) usable for transmitting the voice data, receiving second information from the originating call control node (MSC-S) indicative of a codec (PCM) to be used from the calling party (BSC) towards the at least one media gateway node (MGW-, MGW-) usable for transmitting the voice data, determining whether the voice data is transmittable by the at least one media gateway node (MGW-, MGW-) towards the called party (BSC) encoded by said codec (PCM)determining whether a common media gateway node (MGW-) is usable by both the originating call control node (MSC-S) and the terminating call control node (MSC-S), sending first backward information to the originating call control node (MSC-S) indicative of the said codec (PCM), and sending second backward information to the originating call control node (MSC-S) indicative of the common media gateway node (MGW-).
