<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This "workaround" has probably caused more problems than it solved.
Unfortunately, I don't think this patch will always work.
If the SDP we receive in the first 183 contains a "sendonly" attribute, the remote address on the RTP instance will be 0. This will cause this code to treat a subsequent 183 as Ringing, even though we've received an SDP that negotiates an audio media stream.
As much as I hate 'levers' to control behavior, this may be a situation where it would be appropriate to have a configuration setting to either treat a 183 without an SDP as Ringing or not.
It could default to the existing behavior in 1.8-12; we could change the default to honoring the 183 in 13+.</pre>

Red blobs are a bonus in the review, but will not be offered in commit.</pre>
