What is PBX delivers audio and how to enable/disable the feature

 PBX Delivers Audio routes all audio traffic through the PBX. This helps in situations that the endpoints cannot talk directly between them or there is a network restriction that this option helps overcome. This does add additional audio to the PBX as all traffic needs to go through the PBX. This can cause audio issue if the server does not have the specs to handle the traffic or if the server and the endpoints use different codecs and the audio has to be transcoded
back and forth which does have an impact on quality.

When Call recording is on then audio is routed through the PBX anyway as it needs to be recorded.
For providers it is recommended that the option is always on as there are rare cases that the call might not have audio when connected to a remote extension
