asterisk users - Mar 2015 - Upgrade to Fedora 21, now gv requires rtp ?

I just upgraded to fedora 21. I'm running asterisk 11.6.0. All works 
with Fedora 20.


-- Executing [s at DialOut:15] Dial("DAHDI/1-1", 
"motif/8447/+1212xxxyyyy at voice.google.com,,rTt") in new stack
[Mar  1 21:24:06] ERROR[2477][C-00000000]: rtp_engine.c:259
