  • Patent number: 7486694
    Abstract: A media-gateway controller for call set-up processing when different codecs are used and a method therefor are provided. A storage unit stores a codec conversion table indicating a relationship between a first codec and a second codec in conversion from the first codec to the second codec. A receiver receives first call setting data including codec data of a caller from the caller and receives first call response data including codec data of a callee from the callee as a response to second call setting data having been transmitted to the callee. A data transformer searches the codec conversion table for a first codec using the caller's codec data as an index and adds a second codec corresponding to the searched first codec to the first call setting data to generate the second call setting data.
