Note for Releases Prior to 8.0

The GPU transcoding solution currently does not support more than one non-G711 transcodable codec per leg on a trunk group. Therefore when configuring Packet Service Profiles, do not configure multiple non-G711 codecs on a single leg (This Leg/Other Leg parameters) when specifying the Codecs Allowed For Transcoding within Packet To Packet Control. Refer to Packet Service Profile - CLI or Packet To Packet Control - Codecs Allowed For Transcoding (EMA).

Note for Releases 8.x/9.x

Following issues exist in 8.x/9.x releases:

  • If  the first transcodable codec in the SDP offered by SBC is G.711, and the answer comes for non-G711 codec, then the SBC continues to use CPU resources for non-G711 transcoding.
  • If the first transcodable codec in the SDP offered by SBC is non-G711 and the answer comes for G711, then the SBC continues to use GPU resources for G.711 transcoding.
