On placing an audio call from android to desktop (using the latest android test builds), I'm hearing about a 1 second delay from the start of the call. Somewhere around 10 minutes into the call, this increases to about 2 seconds. The delay seems consistent if I measure it from android to desktop or vice-versa. I've been using a Samsung Galaxy S2 to both Mac and Windows over a local Wifi network. This has also been heard on a Nexus android phone.
Likely related to bug 843687; possibly even a DUP.

bug 842631 describes this a bit better - it's happening in the general gUM smoke test on Android. Nothing to do with the full stack. Let's dupe on that bug.
