Optional If the recorder you use supports only specific codecs, in the Audio Codec section, select the Codec Prioritization check box.
AWE supports only PCMU, PCMA, and G729 audio codecs, and DTMF dynamic codecs such as Dynamic 101. Therefore, you must select codec prioritization and select preferred codecs if you use a WFO recording server.
Optional Select the Allow Preferred Codecs Only check box.
Optional If you require media transcoding, select the Transcode When Needed check box
For transcoded calls, you must configure the transcoded codec as G729AB and/or G711 or set codec prioritization as G729AB or G711MU. For SIPREC, one side of the call is transcoded, and the other side must be on G729AB or G711 or vice-versa. Media streamed to the Recorder must be on either a G729AB or G711 codec.
Optional In the Available column, select the preferred audio and DTMF dynamic codecs that the recorder supports, and click >.
Optional If the recording tone is enabled, select the telephone-event, G729, and PCMU preferred codecs.
Recording tone is not supported for the PCMA preferred codec.
