Use this flag to control how the audio portion of a call on port 0 is treated.

The legacy behavior of treating audio on port 0 as on hold is possible only when this flag is disabled for both ingress and egress trunk groups. If this flag is enabled on just one trunk group, the offer/answer appearing on that trunk group inherits audio-less behavior.
