Codecs

An ordered list of Codecs is displayed. Telephony Services (TS) will try to negotiate the connection to use the first Codec on the supported list. By default, no Codecs are selected. You must select one Codec for the mapping to be valid.

Codec List

Interaction Administrator will only store an ordered list of those Codecs (vocoders) that are checked. The Up and Down buttons are available to order this list. The options available are:

• G.711 mu-law

• G.711 a-law

• G.729AB

• G.723.1

• GSM 06.10

• G.726 32k

• G.722 (G.722 is supported between SIP endpoints, but is not supported for playing prompts or voicemail messages. If audio passes through a media server, it is passed through as G.722, but any plays or recordings are done using a narrowband codec.)

Only the G.711 and G.729 AB Codecs allow the frame size to be modified.

Note:
While you can use the Opus codec to create recordings with higher audio quality and dual-channel audio, you cannot use Opus as a codec for Voice over IP endpoints.
