Assigning the codec

Last Updated : Dec 08, 2021 |

Procedure

  1. Enter change ip-codec-set n or change ip-media-parameters n, where n is the IP codec set number.

    The system displays the IP MEDIA PARAMETERS screen.

    Note:

    The codec set that has to be configured in the IP Network Region must be linked to this IP MEDIA PARAMETERS screen.

  2. Fill in the following fields:
    • Audio Codec: G.711 a-law and u-law (for 10, 20, 30 ms packets), G.729/G.729a/G.729b/G.729ab (for 10, 20, 30, 40, 50, 60 ms packets), and G.723 (for 30, 60 ms packets) depending on the audio codec used for this codec set.

      Note:

      When using G.729 codecs, for outgoing packets, the legacy IP DECT system (ADMM) either uses G.729A or G.729AB.

    • Silence Suppression: y or n depending on the codec you have set.

      The ADMM system does not support silence suppression for G.729 or G.729A codecs.

    • Frame Per Pkt: 2.

    • Media Encryption: none, srtp-aescm-128, or srtp-aescm-256.

  3. Select Enter to save your changes.
