chan_sip+native_bridge_rtp: no directmedia for ptime other than default ptime. 

During capabilities selection (joint capabilities of us and peer,
configured capability for this peer, or general configured
capabilities), if sip_new() does not keep framing information,
then directmedia activation will fail for any framing different
from default framing.
