Transcoding Support

Based on the transcoding resources available, which vary by platform, different codecs may be transcoded from- and to-.

Platform	Supported Codecs (by way of codec-policy in the add-on-egress parameter)
Acme Packet physical platforms Hardware-based transcoding for virtual platforms (PCIe Media Accelerator) The Acme Packet 4900 and the Acme Packet 6400 do not support 40 and 60 packetization times for the EVS codec.

^Footnote 1 Hardware-based EVS SWB and EVS FB transcoding is supported for decode-only.

^Footnote 2 * These codecs require Fax Tone Detection.

^Footnote 3 A telephone-event requires DTMF tone generator and detector.
