Override Preferred DTMF Audio

When DTMF audio tones are supported on both sides of the call, it is the preferred method of DTMF indication transport. To override this behavior, enable the translate non inband event parameter.

Note:

Enabling one or both of these exceptions can cost DTMF translation resources whether they occur in the network processors or on transcoding modules. The translate-non-inband-event exception is especially costing because it reserves transcoding for all calls that resolve to support for DTMFable to DTMFable codecs.
