Configuring Voice Quality for Unregistered Users
You can configure the device to dynamically switch voice coders to improve voice quality during a call with an unregistered user.
If it detects poor voice quality (based on MOS), it switches coders from G.711 to Opus for the unregistered user side. If it subsequently detects an improvement in the network (based on packet loss) during the same call, it switches back to G.711. The device switches coders, by changing between two IP Profiles - one associated with G.711, and the other associated with Opus.

This feature is applicable only to the SBC application. |

This feature is for Server-type IP Groups. |

When the device operates in HA mode, this feature is not supported for HA switchover (e.g., if coder changed to Opus before switchover, after switchover the call remains with Opus until it ends, even if voice quality improves). |
