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)	AMR AMR-WB CN EVRC0 EVRC EVRC1 EVRCB0 EVRCB EVRCB1 EVS^Foot 1 G711FB G722 G723 G726 G726-16 G726-24 G726-32 G726-40 G729 G729A GSM iLBC Opus SILK PCMU PCMA T.38 T.38OFD telephone-event TTY, except on the Acme Packet 1100

Note that the pooled transcoding feature on the VNF uses external transcoding ESBC, as defined in "Co-Product Support," for supported ESBC for the Transcoding-SBC (T-SBC) role.

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