1. A method comprising:
determining, at a computing device, a call security level of a call occurring at a first communication infrastructure; the first communication infrastructure associated with a first security level; the call security level determined from one or more of; a profile of a caller on the call; and audio on the call; and
in response to determining that the call security level and the first security level are misaligned, causing, via the computing device, the call to change to a second communication infrastructure associated with a second security level aligned with the call security level,
wherein determining the call security level from the audio on the call is based on one or more:
given semantics indicated in the audio;
a given topic indicated in the audio;
a given policy indicated in the audio; and
keywords indicated in the audio.
