Currently if you enable ACM model (Account Settings > Advanced > MSRP > 
Connection Model) Blink will put a=active or a=actpass depending on the 
detected NAT type. If you are not behind NAT it will offer actpass.

We have plans to change this: Blink should never offer actpass, since it 
doesn't know what will the other endpoint be and TLS negotiation would 
fail. Also, the setting will be removed and when Blink receives an offer 
with ACM it will prefer it over the relay. For outbound connections 
Blink will always use a=active.

No ETA for this though.
