Randell/Nils:

Thanks for your prompt responses. Here is our concern. We are in the process of 
adding support for WebRTC based clients in our conferencing solution.

Our conference service is hosted in a multi-cluster (and multi-tenant) 
supporting multiple thousands of WebRTC clients. Even though the bandwidth 
savings is going to be small for a single client, considering our volume it's 
going to be some what considerable bandwidth.

Anyway, I will file a bug in Bugzilla as you suggested.

Note: When we negotiate the same (maxaveragebitrate=24000; usedtx=1 and CN 
attribute in SDP), with Chrome, it only sends a SID packet (I assume) every 
400ms as per standard. That way we save considerable bandwidth.
