<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Going out on a limb here, but if this ever occurs, something has gone horribly wrong. We should never masquerade a Snoop channel: that means someone has performed an ast_channel_yank and is now doing something godawful.
It may be worthwhile having an assert in here, or something that indicates that this should not have occurred - even if we do try to 'handle it gracefully'.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">It's perfectly legal for this to happen, an example would be redirecting the Snoop channel to the dialplan. It will continue to work and nothing funky will happen.</pre>

The operation creates a Snoop channel, sends it into a provided Stasis application, and returns a snapshot of it. Once in the Stasis application any normal operation can be done with it (such as recording or placing into a bridge).</pre>
