Review request for Asterisk Developers, Corey Farrell and Matt Jordan.


Changes
-------

Update to using ast_format_none as the initial value for rtp->lastrxformat, rtp->lasttxformat, and rtp->f.subclass.format.


Repository: Asterisk


Description
-------

This prevents a crash on getting the codec rate for unset formats. This can be validly NULL if the RTP instance has never receieved an audio RTP frame which can occur in off-nominal situations.
