Priority order of video codecs used in the 3G-324M negotiation. Priority 1 is the highest priority.

  • None
  • H.263
  • MPEG4
  • H.264

When video transcoding is enabled in the General section of the Routing profiles configuration page, this parameter specifies the priority order in which 3G-324M video codecs are selected by the video transcoder. In this case, video codec selection on the 3G-324M side does not depend on results of negotiation from the IP side.

When video transcoding is disabled in the General section of the Routing profiles configuration page, the Video Gateway uses this setting in conjunction with the IP side negotiation to offer a list of video codecs that do not require transcoding.
