A priority list of the codecs is configured in the AMO CGWB for HG 3500, and accordingly in the AMO STMIB for HG 3575. During codec negotiations, the gateways use the codecs configured in this way.
Examples:
  • Gateway is a DMC endpoint
  • Master connections for HFA and IP trunking

Example

  • HG 3500 (STMI)
