  • If you want to prevent media from using a codec that requires more bandwidth, you should set the maximum bandwidth per session low enough to discourage such use. Call Administrator Control determine the bandwidth limits for each WAN link. Please read the follow the article about Bandwidth utilization by codecs:

  • It depends on the ultimate destination of the call. If it is going to an external gateway (to the PSTN for instance) it will use G711 for a user who is LAN connected to the gateway. Otherwise it will use RTAudio.

    No problem, you need to setup Call Admission Control (CAC)
