Supported Codecs

The IP Profile object in the Web UI is used to define a set of VoIP Parameters used in either a SIP or H.323 channel group. Once the IP Profile object has been configured, a list of vocoders can be added to it through the Vocoder Profile object. The codecs added through the Vocoder Profile will be the list of codecs that will be used during the offer/answer process. During the negotiation process, the IMG 2020 will start with the topmost Vocoder Profile entry under the IP Profile object and work its way down the list until codec negotiation with the far end gateway is satisfied. The user can set the priority of each vocoder profile entry by moving the entry up or down the list. Refer to the topic for information on setting the priority.
