Asynchronous Real-Time Transport Protocol (Async RTP) Question

I received an email from yesterday saying that they will no longer supporting Asynchronous Real-Time Transport Protocol (Async RTP) and I will need to check to see if that is what my PBX system is using.

I was unable to find any setting inside the FreePBX gui and was wondering how I can check to make sure I am not using the Async.

Thank you for you time.

I have same problem here
I called bandwidth tech support. no help at all.
I will post again if I found more info.

Here is the patch added to SVN a long time ago to support Async RTP.

I think it is of little relevance and can be pretty much ignored. Silence suppression is not on my default.
